Introductory Context
"The checklist presented in this topic is designed for the trader running a combined programme of weekly income positions, potential 0DTE trades, and any open monthly positions that have not yet been closed. It is structured as three sequential reviews: a pre-market review (before the Tuesday open), a mid-session review (10:00 to 11:00 AM), and a final review (1:00 to 1:30 PM). Each review has specific action triggers and decision rules that clear the position book progressively through the expiry session. "
Pre-Market Review - Before 9:15 AM
Executed before every Tuesday open (for weekly expiry) and before every monthly last-Tuesday open (for monthly expiry). Step 1: List all open options positions. Record: underlying, strike, type (call/put), long/short, quantity, and current P&L. Step 2: For each position, calculate: distance from the nearest short strike (for short positions), current P&L as percentage of maximum profit/loss, and the session's Max Pain level from Monday evening's option chain. Step 3: Pre-classify each position using the decision framework from Topic 20.13: Status A (profit target achieved), B (partial profit, last session), C (near break-even, last session), or D (at or beyond stop-loss). Step 4: Prepare the expiry-day actions for each position: predetermined close orders at the appropriate price levels (limit orders for each status-driven exit).
Mid-Session Review - 10:00 to 11:00 AM
At 10:30 AM (approximately 75 minutes into Tuesday's session): review all open positions against the first hour's market movement. Action triggers: (1) Any position where the underlying has moved within 50 points of a short strike since the open: close immediately at market prices. Do not wait for the 1:00 PM lunchtime exit. (2) Any position already at the profit target (status A from pre-market): if the limit close order has not filled by 10:30 AM, adjust to market order and close immediately. (3) 0DTE positions entered at Tuesday open: check against the 50 percent premium loss stop. If any 0DTE position has lost 50 percent of its premium, close immediately.
The 10:30 AM review also provides the first reliable read of the expiry day's dominant direction: which way the market moved from the Max Pain reference point (up or down), and whether the Max Pain gravitational effect is active (Nifty moving toward Max Pain) or overridden (Nifty moving decisively away from Max Pain). This directional read informs any 0DTE entries for the day (the Max Pain gravitational play from Topic 20.5, Strategy 2): if the gravitational pull toward Max Pain is active, the appropriate 0DTE entry may be appropriate in this window.
Final Review - 1:00 to 1:30 PM
The mandatory final review and exit window. Step 1: Close ALL short option positions that are still open. Without exception -- regardless of P&L status, distance from short strikes, or market outlook. Every short option position must be closed by 1:30 PM. This includes: short legs of credit spreads, short legs of iron condors, short straddles, short strangles, and any 0DTE short positions entered earlier in the day. Step 2: Evaluate long option positions for hold vs close. Long options that are significantly ITM (more than 2 percent ITM) with less than 2 hours to settlement: the remaining time value is negligible and selling the long option at near-intrinsic value is appropriate. Long options that are OTM with 2 hours to expiry: they are likely to expire worthless -- consider whether the remaining time value (which is now very small) justifies the execution cost of closing versus letting expire.
Step 3: Document the day's decisions. For each position closed or adjusted during the session: record the entry price, exit price, P&L, and the reason for the specific exit timing (profit target, stop-loss, proximity rule, mandatory lunchtime exit). This documentation feeds the monthly programme scorecard review and provides the data for evaluating the expiry-day management framework's effectiveness over time.
Expiry Day Checklist -- Three Reviews
PRE-MARKET (before 9:15 AM): List all open positions. Calculate strike distances and P&L status. Pre-classify A/B/C/D. Prepare limit close orders. MID-SESSION (10:00-11:00 AM): Execute any status-triggered closes. Check proximity alerts. Close 0DTE positions at 50% stop. Assess day's Max Pain direction. Consider 0DTE directional entry if Max Pain gravitational conditions met. FINAL (1:00-1:30 PM): Close ALL short option positions (mandatory). Evaluate long option positions. Document all trades. Confirm clean position book by 1:30 PM.
Post-Expiry Assessment
After Tuesday's close (typically 4:00 to 5:00 PM): complete the weekly cycle assessment. For each position closed during the expiry session: record in the weekly programme scorecard -- entry date, exit date, entry credit, exit cost, P&L, exit reason, and the Max Pain convergence observation (did the underlying settle near Max Pain or diverge?). Calculate the week's net income per lot and the programme's cumulative monthly income. Reset for Wednesday's new entry assessment.
The expiry day checklist is the options trader's equivalent of the pilot's pre-flight checklist: not because the pilot doesn't know how to fly, but because the structured checklist ensures that nothing is forgotten in the pressure of the moment. Options expiry day has enough moving parts -- multiple positions, evolving prices, proximity alerts, time pressure -- that even experienced traders can miss an action without a systematic review. The checklist converts the complex, multi-decision expiry session into a series of verified, documented actions that leave nothing to improvisation.
THE CHECKLIST IN PRACTICE
Dinesh ran three simultaneous positions on the last Tuesday of August 2023. Position 1: Nifty bull put spread (23,000/22,500) -- P&L at 73% profit target. Position 2: FinNifty credit spread -- P&L at 45% profit target. Position 3: 0DTE Nifty call from earlier that morning -- P&L showing a 60% loss (stop triggered). His pre-market checklist had classified them: Position 1 = Status B (73%, 1 session remaining: close immediately). Position 2 = Status B (45%, close immediately per <3 session rule). Position 3 = 0DTE stop triggered: close immediately. By 10:30 AM, all three positions were closed per the checklist's pre-made decisions. Total session work: 15 minutes to close three positions. Total time deviation from checklist: zero. His comment in the diary: 'the checklist made three hard decisions into three button clicks. Without it, I would have held Position 1 for the final 20%.'
Build the Expiry Day Checklist as a Spreadsheet Template
Create a simple spreadsheet template (Google Sheets or Excel) with columns for each expiry day position: underlying, type, strike, quantity, entry price, current price, P&L%, status (A/B/C/D), and action. Fill in the pre-market values before the Tuesday open. During the session: update current prices and check the action column for triggered instructions. This spreadsheet checklist takes 10 minutes to complete before the open and ensures that every management decision on expiry day is executed from the pre-market analysis rather than from reactive intraday judgment. Export or screenshot the completed checklist after the session for the monthly programme review.
