Trade Management & Adjustments — Reference Module

Educational reference only. Not investment advice. Options involve substantial risk of loss, including assignment and total loss of capital; you are responsible for your own decisions.

This module covers what to do with open US equity/ETF/index options positions: when to take profit, when to roll, how to defend a tested side, how to handle assignment, and how to keep the book balanced. It assumes the entry conventions used throughout this manual:

  • Premium selling entered ~30–45 DTE; take profit ~50% of credit (50–75% on iron condors); manage/roll by ~21 DTE; risk cap ~1–2x credit.
  • Debit / directional entered 45–90 DTE; take profits into the move and trail.
  • 1 contract = 100 shares. SPX is European-style, cash-settled, no early assignment. SPY / QQQ / IWM are American-style with early-assignment risk (especially around ex-dividend and on deep-ITM shorts).

1. The management philosophy

Define the exit before the entry. Every position should have, at the moment of entry, three pre-committed numbers written down: a profit target, a management date (~21 DTE for short premium), and a loss/defense trigger (credit multiple or thesis-invalidation). If you cannot state all three before you click, you are not ready to open the trade.

Why mechanical beats discretion:

Discretionary management Mechanical management
Decision made under P/L stress, in real time Decision pre-made, calm, before money is at risk
Loss aversion → hold losers, cut winners early Rules force the opposite (cut/roll losers, harvest winners)
Inconsistent, hard to evaluate or improve Repeatable; you can backtest and audit the rule, not the mood
Anchors on entry price and “being right” Anchors on probability and expected value

Manage winners early. A short-premium position is a decaying position: as time passes and the underlying behaves, the probability of keeping the credit rises and most of the easy profit arrives in the first half of the trade. Closing at ~50% of max profit captures the bulk of the edge in a fraction of the time and risk, then frees capital to redeploy. The last 50% of profit is the slowest, lowest-return, highest-gamma portion of the trade — you are paid little to hold it and exposed to a lot.

Cut or roll losers by rule, not by hope. A losing short option is your least convex position — adverse moves accelerate against you (negative gamma). The rule decides the action; emotion only delays it.

Core stance: harvest winners early (probabilities are decaying in your favor), and act on losers mechanically (roll for a credit if the thesis holds, close if it doesn’t). Never improvise around a number you already committed to.

2. Profit-taking rules (with the “why”)

The general logic: profit-take where marginal return per remaining day, per unit of remaining risk, collapses. For short premium that point is roughly half the credit; for directional debit trades it is somewhere in the move, taken in pieces.

Strategy type Profit target Rationale
Credit (vertical) spread ~50% of max profit Captures most of the theta with far less gamma/duration risk; recycle buying power.
Short strangle / short straddle ~50% of credit Same logic; undefined risk makes early exit even more valuable.
Naked short put / short call ~25–50% of credit Large/undefined-risk single legs (a naked call is unlimited; a naked put’s loss is bounded but large) — take money off fast; the tail risk you carry is not worth squeezing the last dollars.
Iron condor ~50–75% of credit Two short spreads on a range-bound thesis; condors tolerate a slightly higher target because both sides decay and the structure is defined-risk.
Calendar / diagonal ~25–50% of debit, or a vega/term-structure target Profit depends on IV and time spread, not just price; take it when the vol/term thesis has played out.
Debit vertical / long single option (directional) Scale out into the move; trail the remainder You are paying theta every day — convert paper gains to realized gains as the move happens; don’t round-trip a winner.

Mechanics for directional/debit “scaling into the move”:

  • Take a first tranche (e.g., a third to half) when the trade reaches your first target (a measured move, a key level, or a fixed return multiple of the debit).
  • Trail the remainder: roll your mental stop up to break-even after the first scale, then trail behind structure (prior swing, moving average) so a reversal can’t turn a winner into a loser.
  • Remember theta and gamma work against long options near expiry — directional trades opened 45–90 DTE should generally be harvested or rolled out well before the final weeks, not held for the last few cents of extrinsic value.

Why not “let it ride to max profit” on short premium? Max profit only arrives at expiration, which is exactly when gamma/pin/assignment risk is highest. You’d be holding the worst risk profile to earn the smallest remaining increment. The 50% rule is a deliberate trade of a little upside for a lot less variance and faster capital turnover.

3. Time-based management — the 21-DTE rule

Rule: for short-premium positions, make a management decision around ~21 DTE regardless of P/L — close the winner if it hasn’t already hit target, roll it out, or deliberately decide to carry a defined-risk piece a little longer with eyes open.

Why 21 DTE:

  • Gamma accelerates into expiration. In the final ~3 weeks, a short option’s delta becomes increasingly sensitive to price — small underlying moves cause large, fast P/L swings. The smooth theta decay you were harvesting gets dominated by jumpy gamma risk.
  • Theta-per-unit-of-gamma deteriorates. Early in the cycle you collect decay with relatively benign price sensitivity. Late in the cycle the same decay comes bundled with much sharper gamma — a worse deal.
  • You’ve already captured most of the edge. A 30–45 DTE trade managed at 21 DTE has typically realized the bulk of its expected decay. Staying in mostly adds tail risk, not return.

Decision matrix at ~21 DTE:

Situation at ~21 DTE Action
At or past profit target Close. Don’t wait.
Profitable but below target Close or roll out to the next cycle for a credit; redeploy.
Untested, near break-even Roll out for a credit (reset duration, lower gamma), or close flat.
Tested / under pressure Defend per §6 or close; do not simply let undefined risk drift into the gamma zone.

Defined-risk vs undefined-risk near expiry:

  • Defined-risk (verticals, iron condors, defined butterflies): you may let a clearly-winning, comfortably-OTM position run somewhat closer to expiry because your max loss is fixed and small. Even so, 21 DTE is the default decision point, and pin risk on the short strikes still applies.
  • Undefined-risk (naked options, short strangles/straddles): never knowingly hold into the gamma zone. A single gap can produce a loss far larger than the credit. Manage out, roll out, or convert to defined-risk by ~21 DTE.

4. Gamma risk near expiry

Short options become dangerous in the last 1–2 weeks because their behavior changes character: extrinsic value is nearly gone, so the option trades almost like the underlying when near the money, and gamma spikes for at-the-money strikes. Net effect for a short seller: maximum negative convexity exactly when you’re paid the least to hold it.

Three distinct hazards in expiration week:

  1. Gamma whipsaw. An ATM short can swing from “expiring worthless” to “deep ITM” on a single session’s move; your delta flips fast and hedging is reactive and expensive.
  2. Pin risk. When the underlying closes right at a short strike at expiration, you may not know whether you’ll be assigned. You can end up with an unexpected, unhedged stock position over the weekend that gaps Monday.
  3. Assignment risk on ITM shorts (American-style: SPY/QQQ/IWM, single names). Short ITM calls are prone to early assignment around ex-dividend (counterparty exercises to capture the dividend); short ITM puts can be assigned when extrinsic value is gone. SPX is European — no early assignment — which is one reason index traders tolerate holding it slightly longer.

Why most pros don’t hold short premium into expiration week: the remaining credit is small, the gamma/pin/assignment risk is large, and the risk-adjusted return of those final days is poor. The professional default is to be flat or rolled out before the final week, taking the trade off while it’s still smooth.

Heuristic: if the only thing left to earn is the last sliver of extrinsic value, the trade is over — collect it by closing, not by absorbing a week of gamma.

5. Rolling — the core mechanics

Rolling = close the existing position and open a new one, usually as a single combined order to control fill quality and net price. Across all roll types, two rules govern:

(1) Only roll for a net credit (or, for directional/debit repairs, only if it genuinely improves expectancy). (2) Don’t roll just to avoid booking a loss. Rolling is for extending a thesis you still hold or improving a position’s odds — not for refusing to be wrong.

A roll for a credit widens your break-even and reduces cost basis / increases max profit on the structure; a roll for a debit does the opposite and usually just postpones the loss while adding risk. If you cannot roll for a credit, that’s the market telling you the position is genuinely impaired — strongly consider closing.

5.1 Rolling OUT in time (same strikes, later expiry)

  • What: Buy back the current short option(s)/spread and sell the same strikes in a later expiration.
  • When: A short position is being tested or is near break-even around ~21 DTE, but you still believe the underlying will stay on your side; you want more time and to reset gamma.
  • Mechanics: Single order — close near-dated leg(s), open far-dated leg(s) at the identical strikes. Later expiry carries more extrinsic value, so same strikes typically yields a net credit.
  • Credit rule: Yes — roll out only for a credit. The extra credit pays you to take on more duration and lowers your effective basis/break-even. Repeated out-rolls for credit are how undefined-risk positions are “given more room” without paying to do it.
  • Caution: Rolling out does not reduce directional risk, it only buys time. If the underlying keeps moving against you, you’re still exposed — combine with an up/down roll (§5.2) or defend (§6).

5.2 Rolling UP / DOWN in strike

  • What: Move the strike(s) toward (defensive) or with (offensive) the underlying. Roll up = to higher strikes; roll down = to lower strikes.
  • When:
    • Defensive: a short put is being tested by a falling price → roll the put down (further OTM) to widen break-even, usually combined with rolling out so the move can be done for a credit (“down-and-out”).
    • Offensive / profit-protection: a covered call’s stock has rallied and the short call is deep ITM → roll up-and-out to reduce assignment likelihood and capture more upside (see §5.5).
  • Mechanics: Close current strike, open new strike (often in a later cycle). Moving a short strike further from the money generally requires going out in time to keep the trade a credit.
  • Credit rule: Yes. If you can’t move to safer strikes for a credit, the protection isn’t free — reassess vs closing.

5.3 Rolling the UNTESTED side toward price (strangle / iron condor)

  • What: With one side tested and the other side far OTM and nearly worthless, roll the untested short closer to the current price (and/or out in time) to collect additional credit.
  • When: Price has trended toward one side of a strangle/condor; the untested side has decayed to little remaining value, so it’s no longer doing much work.
  • Why it helps: The new credit reduces net risk and widens the break-even on the tested side without adding directional exposure on the threatened side. It’s the cleanest first defensive move because you’re harvesting a side that’s already won and recycling it as protection.
  • Mechanics: Buy back the cheap untested short, sell a new short closer to price (same expiry, or roll out). Keep the structure’s defined/undefined character intact (for a condor, you can also roll the whole untested spread in).
  • Credit rule: By construction this is done for a credit — that’s the entire point. Stop rolling the untested side in once it gets close enough that you’d be uncomfortable if price reversed (you can over-tighten and create a new tested side on the other end).

5.4 Going INVERTED on a short strangle

  • What: Rolling the untested side past the tested strike, so the strikes cross (in the example below, the put strike ends up above the call strike — the strangle is “inverted”).
  • Example: Short strangle with put @ 95 / call @ 105; price rips to 115. You roll the untested put up above the call — e.g., put now @ 108, call still @ 105 → strikes are inverted (108 put / 105 call).
  • When justified: Only as a late-stage defense on a tested undefined-risk strangle where (a) you still want to stay in rather than realize the loss, (b) you can do the inversion for a credit, and © the credit collected narrows your max loss. Inverting locks in a guaranteed intrinsic loss equal to the width of the inversion, but the extra credit can offset it and define a tighter worst case if price stays between the inverted strikes.
  • Mechanics: Roll the untested short across the price to the other side of the tested strike, collecting credit. Often combined with rolling out in time to make the credit work.
  • Caution: This is an advanced, undefined-risk maneuver. The inversion width is a locked loss; you’re betting the underlying settles back between the inverted strikes. If you wouldn’t re-open this exact risk fresh, don’t invert — just take the loss.

5.5 Rolling a covered call / cash-secured put

Covered call (you own 100 shares, short 1 call):

  • Up-and-out (rally, call going ITM, you want to keep the shares): roll the short call up to a higher strike and out in time for a net credit. Trade-off: you reduce near-term assignment risk and raise your effective sale price, but you cap less upside than before and tie the shares up longer. If you’d be happy to sell at the current strike, it’s often better to let assignment happen and book the gain.
  • Decision: roll up-and-out only if (a) you want to retain the shares, and (b) the roll is a credit. If neither holds, allow assignment (you sell shares at the strike — a planned outcome of a covered call).

Cash-secured put (you’re short 1 put, cash set aside):

  • Down-and-out (price falls toward/through the strike, you want to avoid or delay assignment): roll the short put down to a lower strike and out in time for a credit, lowering the price at which you’d be obligated to buy.
  • Decision: roll down-and-out only if (a) you’d rather not own at the current strike yet, and (b) it’s a credit. If you’re happy to own the shares at the strike, just take assignment and proceed to the Wheel (sell calls against the new shares — see §9).

Assignment trade-off summary: A covered call and a CSP are designed to be assigned at favorable prices. Roll to keep the position alive when you still prefer the stock outcome you originally wanted; accept assignment when the assignment is the outcome you wanted. Never roll a covered call/CSP for a debit purely to dodge an assignment you’d actually be fine with.

6. Defending a tested side (credit spread / iron condor)

A short strike is “tested” when price reaches or breaches it (short-strike delta climbing toward ~0.30–0.50+). Work the menu in order of least cost / least added risk first, and always ask the gating question before adjusting at all.

Gating question — is the thesis still valid? A range/neutral thesis is invalidated by a sustained, confirmed directional break (gap through the strike on volume, trend change, regime shift, news). If the move invalidates the thesis, do not adjust — take the loss and close. Adjusting only makes sense when you still expect price to behave; otherwise you’re adding risk to a broken idea.

        If no further credit available                6) If none works for a credit
        and thesis intact -> hold to defined             -> CLOSE
        max loss (defined risk only)

6.2 The defensive menu, ranked

# Move What it does Use when
1 Take profit / roll untested side in (§5.3) Harvests the won side, collects credit, widens break-even First response on a strangle/condor — cheapest, no added directional risk
2 Roll tested spread out in time (§5.1) Buys time, resets gamma, collects credit Thesis intact, just need more room and time
3 Roll tested strikes further OTM (§5.2) Moves break-even away from price Combine with #2 to keep it a credit
4 Widen the tested spread Sells a further short / buys a further long to take in more credit and push break-even Defined-risk; you accept a larger max loss for a wider profit zone
5 Convert e.g., turn a tested put spread into an iron condor by selling a call spread for credit You now have a mild opposite lean and want extra credit to offset
6 Close Realize the loss, free capital Thesis invalidated, or nothing above can be done for a credit

6.3 When NOT to adjust

  • The directional move has invalidated the neutral/range thesis → close, don’t martingale.
  • You can no longer adjust for a credit → the market is pricing real risk; rolling for a debit just enlarges the loss.
  • The adjustment would push you past your per-position risk cap (~1–2x credit) or break portfolio limits (§11).
  • You’re adjusting only to avoid admitting the trade is wrong — that’s the textbook signature of a loss that compounds.

A good adjustment improves your position (more credit, wider break-even, better odds) on a thesis you still hold. A bad adjustment defers a loss on a thesis that’s broken. Know which one you’re doing.

7. Stops and loss rules

Hard price stops behave poorly on multi-leg option spreads. Options markets are wider and thinner than the underlying, especially intraday and on the wings. A price-triggered stop on a spread tends to:

  • Whipsaw — fire on a momentary quote spike, then watch the spread recover (you’re stopped out for nothing).
  • Fill badly — a stop becomes a market order into a wide bid/ask; you cross a large spread and realize a worse loss than the “stop” implied.
  • Mismeasure risk — the mark on a spread can swing on stale or skewed quotes even when the real, executable value hasn’t moved.

Use one of these instead:

Stop type Definition Best for
Credit-multiple stop Exit when the loss reaches a multiple of credit received, e.g. 2x credit (so a position taken in for $1.00 is closed near $3.00 mark loss, i.e. ~2x the credit lost). Aligns with the ~1–2x credit risk cap. Undefined-risk and wider defined-risk short premium
Delta / breach trigger Act when the short strike’s delta crosses a threshold (e.g., ~0.30→ watch, ~0.45–0.50 → defend) or price touches/closes through the short strike. Decision signal to defend (§6) rather than a blind exit
Thesis-invalidation stop Exit when the reason for the trade is gone (range broke, trend changed, event surprised). Tied to the chart/news, not the option mark. Directional trades and any position where “why” can be falsified cleanly

Implementation notes:

  • Prefer alerts that prompt a manual, limit-order exit over resting stop orders on spreads — you control the fill instead of crossing a wide market under duress.
  • A credit-multiple stop and a delta/breach trigger often coincide near the short strike; use the breach as the signal and the credit multiple as the hard ceiling.
  • Evaluate stops off realistic mid/executable prices, not the last print on an illiquid wing.

Defined-risk “let it ride to max loss” sizing logic: For small, far-OTM defined-risk positions (e.g., a tight credit spread or condor wing), the cleanest “stop” can be no stop at all — as long as you sized the position so that max loss is acceptable. If a single position’s max loss is a tolerable fraction of the account, you can skip the whipsaw-prone intraday stop and either defend by rule (§6) or simply accept the capped loss. This only works when you sized it that way at entry — it is a sizing decision, not an excuse to ignore a blown-out undefined-risk trade.

Undefined risk always gets a real stop (credit multiple / breach / thesis). Defined risk may be sized to ride to max loss. Decide which regime you’re in at entry.

8. Managing winners vs losers

Winners — take them at target, full stop.

  • Hit your profit target (§2)? Close, even though “it could go further.” The expected value of the remaining premium is small and the remaining risk (gamma/time) is not. You sized and structured the trade to capture the first, fattest part of the move — collect it and recycle the capital.
  • “It could keep going” is a reason to open a new trade with a fresh, full risk budget — not to overstay a trade whose risk/reward has already inverted.
  • Don’t move targets up on a winning short-premium trade; that’s discretion sneaking back in.

Losers — roll vs close is a two-question test:

Question If YES If NO
Do you still believe the thesis? (range intact / direction intact) Proceed to next question Close. Take the loss; don’t defend a broken idea.
Can you roll for a net credit (out in time, untested side in, strikes away)? Roll per §5/§6 — extend the trade, improve break-even, no added net debit Close. No credit available = market says the position is genuinely impaired.
  • Respect the risk cap. If defending would push the position past ~1–2x credit (undefined) or your defined-risk max-loss budget, stop defending and close — even if both questions were “yes.” The cap outranks the roll.
  • Don’t add size to a loser beyond what a credit-roll naturally implies. Doubling contracts to “average down” a short-premium loss is how a manageable loss becomes an account event.

9. Assignment response playbook

Assignment converts an option obligation into a stock position. Stay calm — it’s a known, mechanical event, not an emergency. (Reminder: SPX = no early assignment; SPY/QQQ/IWM and single names = American, watch ex-dividend on short ITM calls.)

9.1 Assigned early on a short put → you now own 100 shares (long stock)

  1. Was this acceptable? A cash-secured put assigned at your strike means you bought stock at a price you pre-approved. Often the intended outcome.
  2. Options now:
    • Sell calls against the shares (start/continue the Wheel): sell a ~30–45 DTE call at/above your cost basis to collect premium and define an exit. This is the standard continuation.
    • Close the shares if the thesis is gone or you don’t want the directional/overnight risk — sell the stock, book the result, move on.
  3. Watch overnight/gap risk on the new long stock until you’ve covered it with a call or exited.

9.2 Assigned early on a short call → you now are short 100 shares (short stock)

  1. Short stock is open-ended risk and incurs borrow — treat it as more urgent than a long-stock assignment.
  2. Options now:
    • Buy back / cover the short stock immediately if it was unintended (most common for a naked short call or a covered call where you’d rather keep shares but got assigned).
    • Sell puts against the short stock (the inverse Wheel) only if you deliberately want short exposure and to collect premium.
    • For a covered call, early assignment simply means your shares were called away at the strike — usually fine; if it was an ex-dividend early call and you wanted the dividend, you may re-evaluate, but don’t chase.

9.3 Assignment on ONE leg of a spread

  • A vertical’s short leg can be assigned while the long leg remains an option. You’ll wake up with stock + a long option, not the neat spread.
  • Response: you still hold the long option as protection. Exercise or sell the long leg and unwind the stock to flatten back to defined risk; or simply close the entire resulting position (sell/buy the stock and sell the long option). Don’t leave an unhedged stock position drifting.
  • Your max loss is still capped by the spread width — early assignment changes the form, not the defined-risk ceiling. Avoid panic-trading; reconstruct or close in a single clean step.

9.4 Pin risk at expiry (short strike ~ at the money on expiration)

  • If the underlying settles right at your short strike, you may not know until after the close whether you were assigned → risk of an unhedged weekend stock position that gaps Monday.
  • Avoid it: close any short option that is near the money going into expiration (don’t gamble on the pin). This is a primary reason for the §3–§4 “be flat before expiration week” stance.

9.5 The do-nothing / let-it-expire case

  • If all legs are comfortably OTM at expiration, the cleanest action is none — let them expire worthless and keep the full remaining premium. (Some traders still close for a few cents to be certain and to free buying power; either is defensible.)
  • Never let an option you’re unsure about (near the money, or ITM) “just expire” hoping it resolves your way — that’s pin/assignment roulette. Certainty OTM = fine to let expire; anything near the strike = close it.

10. Earnings / events while in a trade

Treat any scheduled binary event — earnings, FOMC, major economic prints, drug/legal/regulatory dates — as a pre-planned decision, not a surprise. Mark these dates on every position at entry.

General rule: Do not hold undefined short premium through a binary event unless that was the explicit plan. A gap can blow straight through any credit-multiple stop — stops don’t help across a gap. The trade either was an earnings/IV play (sized for it) or it should be flat/neutral before the event.

Position type Default action into a binary event
Naked short options / short strangle/straddle (undefined) Close or convert to defined risk before the event — unless this was a deliberate, properly-sized earnings/IV-crush play.
Defined-risk short premium (verticals, iron condors, defined butterflies) May hold through if max loss is acceptable and it’s part of the plan; otherwise close. The defined cap is what makes holding tolerable.
Long/debit directional Decide explicitly: hold for the catalyst (accept gap risk + IV crush working against long premium), or take profits/scale before and re-enter after.
Covered call / CSP Usually hold (you accept the stock outcome), but know that earnings can gap the underlying past your strike.

Extra considerations:

  • IV crush: implied vol typically collapses after the event. Good for short premium that survives the move; bad for long premium that needed a big directional pop to overcome the vol drop.
  • Roll past the event if you want to stay in a short-premium trade without holding through it — roll to an expiry after the event so you’re not exposed during the binary print (only for a credit).
  • Macro events (FOMC, CPI) hit the whole book at once — manage at the portfolio level (§11), not just position-by-position.

11. Portfolio-level management

Individual trades can each be “fine” while the book is dangerously concentrated or directional. Manage the aggregate.

11.1 Beta-weighted net delta

  • Beta-weight every position’s delta to a common benchmark (commonly SPY) so positions on different underlyings are expressed in comparable units, then sum to a single net number.
  • Target: keep the book roughly neutral or within a chosen directional band you’ve decided on deliberately (e.g., a small long or short tilt that reflects your market view and risk appetite). The point is that the tilt is intentional and bounded, not an accident of stacking same-direction trades.
  • Rebalance with the cheapest available lever: adjust/close an offending position, add an offsetting position, or use a small index hedge — bring net beta-weighted delta back inside the band.

11.2 Net vega and net theta across the book

  • Net theta: for a premium-selling book, theta is your income engine — know your daily theta and keep it sized to the account, not ballooned by over-deploying.
  • Net vega: short-premium books are typically net short vega (you profit as IV falls, lose as IV spikes). Track aggregate vega so a single vol shock doesn’t exceed what you can stomach. Don’t let net short vega scale up just because IV is high now — that’s exactly when a spike hurts most.
  • Balance: when net short vega gets large, consider adding a long-vega or defined-risk structure, or trimming, so a VIX spike is survivable.

11.3 Position-count and correlation limits

  • Cap the number of concurrent positions to what you can actually manage (monitor, defend, roll) — an unmanageable book defeats mechanical management.
  • Correlation: five “different” short put trades on highly correlated names (or several index proxies) are one big trade in a sell-off. Limit aggregate exposure to any single sector / theme / correlated cluster, not just per ticker.
  • Buying-power utilization: keep meaningful dry powder. Running near max BP leaves no room to defend, roll, or survive a margin expansion when IV spikes (margin requirements rise exactly when you’re stressed).

11.4 Regime shifts (IVR / VIX)

Regime Posture
Low IVR / low VIX Less premium to sell; reduce size, widen strikes for the same credit is harder, lean more selective. Avoid over-trading just to stay busy.
High IVR / high VIX Richer premium, but bigger moves and rising margin. Size down per trade even though credits look attractive; keep more buying power; expect to defend more often.
Regime shifting (vol expanding fast) Reduce gross exposure, tighten net delta toward neutral, prioritize defense over new entries. Don’t add net short vega into an expanding-vol tape.

The book has its own profit target, risk cap, and stop — at the portfolio level. Net beta-weighted delta, net vega/theta, correlation, and BP utilization are the dashboard; check them before adding any new position.

12. The adjustment decision flowchart

Run this in order on any open position whenever you review it (a trade hits an alert, the daily review, ~21 DTE, or an event approaches). First match wins.

START: review an open position
  |
  1. At / past PROFIT TARGET? ........................ YES -> TAKE IT. Close. (Done.)
  |                                                     NO  v
  2. ~21 DTE (short premium)? ........................ YES -> MANAGE: close winner, or
  |                                                            roll OUT for a credit, or
  |                                                            (defined-risk, comfortably OTM)
  |                                                            decide to carry briefly. (Done.)
  |                                                     NO  v
  3. SHORT STRIKE TESTED / breached? ................. YES -> DEFEND per Section 6:
  |     (delta ~0.45-0.50+ or price through strike)            - thesis broken? CLOSE
  |                                                            - else roll untested in /
  |                                                              roll out / widen / convert
  |                                                              (only for a CREDIT). (Done.)
  |                                                     NO  v
  4. THESIS INVALIDATED? ............................. YES -> CLOSE. Take the loss. (Done.)
  |     (range broke / trend changed / event surprise)  NO  v
  5. Loss >= risk cap (~1-2x credit) OR portfolio .... YES -> CLOSE / reduce. (Done.)
  |     limit breached (delta band, vega, BP)?          NO  v
  6. Binary EVENT before expiry & not the plan? ...... YES -> Close / neutralize / roll
  |     (earnings, FOMC) — esp. undefined risk                past the event for credit. (Done.)
  |                                                     NO  v
  7. None of the above ............................... HOLD. Let it work. Re-check next review.

Compact checklist version (tick top-down, act on the first “yes”):

  • [ ] At profit target → take it
  • [ ] ~21 DTE → manage / roll out for credit
  • [ ] Short strike tested → defend per §6 (only for a credit; close if thesis broken)
  • [ ] Thesis invalidated → close
  • [ ] Risk cap or portfolio limit hit → close / reduce
  • [ ] Binary event ahead and not the plan → close / neutralize / roll past it
  • [ ] Otherwise → hold and re-check next review

Golden rules of management

  • Define the exit before the entry — profit target, ~21-DTE management date, and loss/defense trigger are set before you open, never improvised under P/L pressure.
  • Harvest winners early (~50% credit; 50–75% on iron condors; 25–50% naked; scale into the move on directional) — the last increment of profit carries the worst risk-adjusted return.
  • Respect ~21 DTE and avoid the gamma zone — make a decision by 21 DTE and don’t carry undefined short risk into expiration week.
  • Only roll for a credit, and never roll just to avoid taking a loss — a roll extends a thesis you still hold or improves your odds; it does not rescue a broken idea.
  • Defend only a thesis that’s still valid — if the move invalidates the trade, close it; adjusting a broken position only compounds the loss.
  • Use credit-multiple / breach / thesis stops, not hard price stops on spreads — and size defined-risk positions so you can ride them to max loss when that’s the chosen regime.
  • Manage the book, not just the trade — keep beta-weighted net delta in band, net vega/theta and correlation under control, dry powder in reserve, and size down when the vol regime shifts.
