Adjustment playbook

← Strike selection is where you picked the original strike. Sometimes the market walks it back to you — a short −0.30 put drifts toward −0.40 as DTE shrinks and spot drifts toward your strike. The mechanic is the same as opening a Wheel trade, just inverted: buy-to-close the current put, sell-to-open a new one at a lower strike and/or a later expiry. Two legs, one combined order.

When to act. Three signals line up: delta ≥ −0.40, DTE ≤ 21 days, and spot within 1–2% of your strike. Inside that window, gamma is starting to dominate theta and every day the position behaves more like a stock substitute than an option trade.

The credit requirement. The new short put must collect enough premium to cover what you paid to close and leave at least $0.30 of net credit per contract. Worked example on AAPL @ $230: buy-to-close the $225 / 21-DTE short put at $3.80, sell-to-open the $220 / 35-DTE short put at $1.20. You pay $3.80, receive $1.20, and buy 14 extra DTE while dropping delta from −0.40 to −0.30. The position is now solvent again.

Risk framing. Buying-power exposure does not change — you still have $22,000 of cash reserved against the same notional $100 of AAPL exposure. What you traded is time — more DTE, less gamma — and a lower breakeven ($218.80 under the new strike instead of $221.20). If you can't net a credit, don't roll — close the whole position and redeploy.

Rule of thumb. Only roll when net credit ≥ 25% of the original premium AND new delta is closer to −0.20. Otherwise close and re-evaluate.

The mirror case. The underlying rallies past your short call strike and your covered call goes in-the-money. You have two outcomes: let assignment fire (shares leave at the strike and you redeploy cash into a fresh CSP), or roll up and out: buy-to-close the current call, sell-to-open a new one at a higher strike and later date, ideally for net credit.

When to roll. Only if you genuinely want to keep holding the shares through the new DTE window. Rolling to chase a few dollars of extra premium — when you would have happily taken the assignment at the current strike — usually costs more than it earns, because you give back unrealised share appreciation in exchange for time.

Worked example on SPY. You hold 100 shares of SPY at a cost basis of $580. You sold a 35-DTE $595 covered call for $3.20 (+0.30 delta at open). The market rallies — spot is $605 and the call is now deep ITM at $9.80, six days from expiration. You roll up and out: buy-to-close the 6-DTE $595 call at $9.80, sell-to-open a 30-DTE $600 call at $9.70. Net: $0.10 debit per share, $5 higher strike, 24 extra DTE.

Risk framing. The debit is small but real — you paid $10 across 100 shares to defer a sale at $595 to a potential sale at $600. The premium you forfeit is the price of holding the position longer — that trade only makes sense if $600 is a price you actually want to own SPY through. If you'd rather lock in the gain, just take the assignment.

Rule of thumb. Roll up-and-out only if you'd be comfortable holding the shares for the longer DTE window at the new strike — if you'd rather sell, just take the assignment and start a fresh CSP.

Assignment isn't a failure. It's the second half of the cycle: shares leave your account at the strike, the premium you already collected is realised, and your cash comes back ready to redeploy. Letting the broker exercise the call is almost always cheaper than the implied leg of rolling endlessly.

The clean reset. When the call is exercised, three things settle simultaneously: the short-call premium (already yours), the short-put premium if you were originally assigned through a CSP, and the share sale proceeds (strike × 100). You end with $60,000–$80,000 in cash (depending on the strike), no position, and full optionality on the next entry point.

Worked example on NVDA. You were assigned 100 shares of NVDA at $135 (cost basis $132.60 after the original $2.40 put premium). You sold a covered call at $150 for $2.10. Spot closes at $152 on expiration — shares called away at $150. Net realised P&L: +$4.50 per share ($17.40 appreciation + $4.50 of put+call premium, minus $17.40 cost-basis delta). 100 shares × $4.50 = $450 in realised premium-style income, with $15,000 of capital gain nested inside.

Redeploy. Immediately sell a fresh CSP — same strike as the one that just paid off if the chart setup is unchanged, or one tick ITM to capture richer premium if IV rank has climbed during the ride. If premium is thin (IV rank below ~25%), wait a week or two rather than fudge a strike.

Risk framing.There is no penalty for taking assignment. The realised premium + sale price is your P&L — full stop. The temptation to roll endlessly to chase an extra $0.05 of credit is the real risk: each roll compresses your exit strike (covered calls) or extends your breakeven (puts), and the small premium you chase rarely justifies the open-ended exposure you keep.

Rule of thumb. If the call would put you out at a price you'd happily sell at anyway, take the assignment and immediately re-sell a new CSP — don't roll to chase an extra $0.05 of premium.
