What is the OCC deadline and why is my broker's earlier?
OCC, the clearing house for listed options, accepts exercise and do-not-exercise instructions on expiring equity and ETF options until 5:30pm ET on expiration day. It does not take them from you: it takes them from clearing firms, and each broker needs time to collect instructions from its customers, check them and pass them on. So every broker sets its own earlier window, and that window is the one that binds you. Per the table below: Robinhood 5:00pm ET, Charles Schwab (thinkorswim) not confirmed from an official page, tastytrade 4:30pm ET, Interactive Brokers 5:25pm ET, Webull 4:00pm ET. Robinhood's app and web exercise requests close at 4:00pm ET, with later requests handled on a best-efforts basis. Missing the broker window does not mean nothing happens — it means OCC's default applies: an expiring SPY or QQQ option in the money by $0.01 or more at the 4:00pm ET close is exercised, and one that is not is left to expire. The sourced instrument facts are on what happens if my SPY 0DTE expires in the money.
What happens to a long ITM option I did not act on?
It is exercised automatically if it is in the money by $0.01 or more at the 4:00pm ET close. A long 650 SPY call becomes 100 shares bought for $65,000 per contract; a long put becomes 100 shares sold at the strike, or a short position of 100 shares if you do not own them. Shares and cash settle T+1. If the account cannot carry that position, the broker's policy decides the next step, and it varies: Robinhood may try to sell the option in the last 30 minutes before the close or submit a do-not-exercise request; Schwab may issue a do-not-exercise instruction or close the position at its discretion; tastytrade's risk team may close positions with expiration risk; Interactive Brokers simulates expiration and may liquidate or lapse; Webull reserves the right to act but is not obligated to. If shares do arrive with a shortfall, expect a margin call or a liquidation of the shares. The per-broker tracker keeps each policy dated.
What happens to a short ITM option?
It is normally assigned, and there is nothing for you to submit. OCC assigns exercises to clearing firms, which allocate them to customer accounts, usually at random; a short SPY call in the money by $0.01 or more at the 4:00pm ET close means delivering 100 shares per contract at the strike, or going short 100 shares if you do not hold them, and a short 650 put means buying 100 shares for $65,000. The notice typically arrives after the close or the next morning, and the shares settle T+1. The short side has no cutoff to miss because it has no decision to make. What it does have is uncertainty: a short contract out of the money at 4:00pm ET can still be assigned if a holder exercises before the cutoff after an after-hours move, and one barely in the money may not be. The only way to remove that question on expiration day is to close the contract before 4:15pm ET, when trading in the expiring SPY option ends.
Can I still submit a do-not-exercise after 4:00?
Depends on the broker, and the minutes are tight. Robinhood's app and web requests close at 4:00pm ET, with later requests handled on a best-efforts basis until 5:00pm ET. tastytrade takes exercise and do-not-exercise requests through its Trade Desk until 4:30pm ET (3:30pm CT), best efforts to 5:30pm ET. Interactive Brokers must receive requests by 5:25pm ET through the Option Exercise window or a Message Center ticket, and exercises and lapses are irrevocable. Webull lists 4:00pm ET, the market close. Schwab's own cutoff is not stated on the page we checked, so the row is flagged unverified in the table below; call the broker before relying on it. After every broker window has closed, OCC's default applies at $0.01. One route that still exists after 4:00pm ET: expiring SPY and QQQ contracts trade until 4:15pm ET, so closing the position in the market removes the exercise question without any instruction. Arithmetic, not advice.
Why is SPX different?
There is nothing to submit. SPX 0DTE contracts (PM-settled SPXW) are European-style and cash-settled: at 4:00pm ET on expiration day, the official S&P 500 closing value fixes every contract, and an in-the-money one is credited or debited intrinsic value × 100 per contract the next business day. No shares change hands, so there is no exercise-by-exception at $0.01, no do-not-exercise instruction, no broker window, and no after-hours move that can change the outcome. Trading in the expiring contract also stops at 4:00pm ET, 15 minutes earlier than SPY and QQQ. A 7700/7710 SPXW call spread with the close at 7725 settles to a net $1,000 in cash, with no leg left to exercise — the full arithmetic is on SPX 0DTE spread at expiration, and the single-leg version on what happens if my SPX 0DTE expires in the money. The short side is covered on can you get assigned on SPX 0DTE?
What does a broker do at 3:30 with a position I cannot afford to take delivery on?
It depends on the broker's published policy, and most of them keep the right to act without telling you first.

Quick answers
What is OCC's exercise cutoff on expiration day?
5:30pm ET for expiring equity and ETF options. Brokers set earlier cutoffs for their customers: Robinhood 5:00pm ET, Charles Schwab (thinkorswim) not confirmed from an official page, tastytrade 4:30pm ET, Interactive Brokers 5:25pm ET, Webull 4:00pm ET.
What happens if I miss my broker's exercise cutoff?
OCC exercise-by-exception applies: an expiring SPY or QQQ option in the money by $0.01 or more at the 4:00pm ET close is exercised, and one that is not expires.
Will my SPY 0DTE call be exercised if I do nothing?
Yes, if it is $0.01 or more in the money at the 4:00pm ET close. One 650 call becomes 100 shares bought for $65,000, settled T+1, unless your broker closes or lapses it first under its own policy.
Can I submit a do-not-exercise instruction after 4:00pm ET?
Depends on the broker: Robinhood app/web 4:00pm, Schwab not stated, tastytrade 4:30pm, IBKR 5:25pm, Webull 4:00pm (all ET). OCC's own cutoff is 5:30pm ET.
Is there an exercise cutoff for SPX 0DTE?
No. SPXW options are European-style and cash-settled at the 4:00pm ET official closing value; there is no instruction to submit.
Do I need to do anything if my short option is in the money?
No instruction is needed or accepted from the short side; assignment is decided by OCC and the broker, with the notice after the close and shares settling T+1.
