OPEX, rolls, and calendar spreads.

Equity positions don't expire — you can hold them indefinitely. Options do. Every options position the framework approves carries a clock, and the clock forces decisions that equity never demands. OPEX week introduces dealer-flow distortion the framework's gamma reads (Lesson 27) get loud about. Rolls mechanically extend a position's life when the thesis holds but expiration is approaching. Calendar spreads are a structural way to express a thesis that respects the time dimension. The options operational layer is where the time-axis discipline lives — and most retail options blow-ups happen because the trader didn't plan for the clock at entry.

OPEX week — what changes for held options

The third Friday of every month is monthly options expiration. Quarterly OPEX (Mar/Jun/Sep/Dec, "quad-witching") layers index futures + index options on top. Two distortions:

Pinning — heavily-optioned underlyings tend to gravitate toward high-OI strikes as expiration approaches. Lesson 27's gamma walls become magnetic. A $230 NVDA position with 50/50 calls/puts at $230 strike often pins right at $230 through Friday close.
IV crush post-expiry — implied volatility on expired contracts goes to zero. The framework's IV percentile computation handles this; the trader holding monthly options watches the IV component of their position decay sharply during OPEX week.

Operational rule: held options through OPEX week need a written plan for "if pinned, what do I do Friday at 3:50pm?" Three options: close out, roll forward, let expire (worthless or assigned). Pick before OPEX week starts; don't decide at 3:50pm.

Roll mechanics

A roll closes the current option and opens a new one with later expiry (and sometimes different strike). Two reasons to roll:

Thesis holds, time runs out. Your $245 NVDA call expires Friday; the structural setup hasn't played out yet but the level is intact. Roll to a $245 call expiring 30 days later. Cost: the time-decay difference between the two contracts.
ITM call you want to keep without taking assignment. Long $230 call on NVDA at $245 — the call is $15 ITM. Letting it expire means assignment (or auto-exercise on most brokers). Roll to a 30-day-out call at a higher strike to preserve directional exposure without the assignment.

What you don't roll: losing options where the thesis broke. Rolling a losing position is sunk-cost fallacy in time-decay form. Close the losing option, take the loss, re-evaluate. The framework's Options Coach explicitly refuses rolls on thesis-broken positions.

Calendar spread mechanics

A calendar spread is selling a near-dated option and buying the same strike further-dated. Net debit. The bet: time decay erodes the near-dated faster than the further-dated, so the spread widens (you profit). Best when the underlying stays close to the strike and IV stays elevated.

The framework treats calendars as a Level-2 options structure — slightly more complex than the Level-1 long calls/puts/verticals. Position sizing same as other options (1-2% portfolio risk). The trader needs to understand that calendars profit from time and stable price, not directional movement. They lose if the underlying makes a big move in either direction (the further-dated leg gains less than the near-dated loses).

⌬ Roll decision calculator

Current option premium$0.40

Roll target premium$1.50

Days to expiry (current)3 days

Thesis intact?Yes

Roll cost (debit)$1.10/contract

Recommended actionROLL — thesis intact, premium reasonable

Current option at $0.40 (mostly time decay), 3 days to expiry. Roll target $1.50 with 30+ days. Net debit $1.10/contract — reasonable cost to extend the directional view by a month. Thesis intact = the original entry rationale still holds. Roll approved.

Set thesis to "broken" — recommendation flips to CLOSE regardless of cost. Push roll target above $3 — debit becomes too expensive relative to size; better to close and re-evaluate fresh. Set DTE to 15+ days — no urgency; recommendation defers to "wait if thesis intact."

The "let it expire" decision

Three cases:

Worthless OTM at expiry — let it expire. Cost: the original premium (already a sunk cost). Don't pay slippage to close a $0.05 contract.
ITM with assignment risk — close before expiry unless you actually want to take the underlying assignment. Most retail accounts auto-exercise ITM at expiry; the trader should know if their broker does this and how.
Pinning at the strike — gamma pull keeps it within $0.05 of the strike. 50/50 ITM/OTM through Friday close. Decide ahead of time: close, roll, or take the random outcome.

What the framework does

Options Book surface tracks every held options position with DTE, current premium, P&L, and a roll/close recommendation per the Options Coach
OPEX week flag on the Velocity Panel during the third week of every month, intensified during quad-witching
Pinning prediction for high-gamma positions at OPEX — surfaces the magnetic strike with a confidence chip
Roll automation via the Options Coach when thesis is intact and DTE under 7 days — surfaces the roll, doesn't auto-execute

The real lesson

Options carry a clock that equity doesn't. OPEX week introduces pinning + IV crush; rolls extend life when thesis holds; calendars are a time-stable strategy. The disciplined options trader plans for the clock at entry — picks an expiry that spans the catalyst with buffer, knows the roll-or-close decision before OPEX week starts, refuses to roll losing positions just to delay the loss. The framework's Options Book makes the clock visible; the operational layer's job is to act on it before time expires.
