Options trade recordkeeping checklist

Record the contract before you record your opinion. Write the underlying, call or put, strike, expiration, option style, multiplier, deliverable, quantity, and whether the series is standard or adjusted. A familiar ticker is not enough when several expirations and strikes sit next to one another.

The option contract multiplier converts a quoted per-share premium into a contract amount. If the quote is 2.40 and the multiplier is 100, one contract represents 240 before fees. An adjusted contract can have a different deliverable, so copy the terms shown by the broker or clearing notice instead of applying a remembered 100-share rule.

For a multi-leg position, list every leg in the same order each time. Include the ratio, buy or sell side, open or close effect, and the expected position after all legs fill. A strategy name such as “spread” does not identify the strikes, dates, or assignment exposure by itself.

Save the quote snapshot that was available when you chose to act. Record the timestamp and time zone, bid, ask, displayed sizes, midpoint if you used it, recent trade if relevant, and the session in which the quote was eligible. The option bid-ask spread is a cost and an execution constraint, not a decorative field.

Write the reason for the trade in measurable terms: the price range you expected, the date by which it had to matter, the implied-volatility assumption, the event that could invalidate the idea, and the maximum loss you accepted. “Bullish” or “bearish” alone cannot be tested later.

Use a small hypothetical to make the record auditable. Suppose two calls are quoted 2.30 bid and 2.50 ask, and you submit a 2.40 limit. If both contracts fill at 2.40, the premium is 2 × 2.40 × 100 = 480 before fees. Record the quote range, the limit, the quantity, and the assumption that both fills were possible; do not rewrite the entry later using a more convenient midpoint.

Keep the order ID, submission time, route or venue when shown, order type, limit or stop condition, time in force, and cancellation or replacement history. A Day order and a longer-lived order can create different exposure even when the price and quantity match.

Match each fill to the order. Record the fill time, price, quantity, partial-fill status, commissions, exchange fees, and any cash debit or credit. Recalculate the average only after the individual fills are preserved. For a multi-leg order, reconcile each leg and the net debit or credit; one filled leg can leave a temporary position that is materially riskier than the planned structure.

Use this simple check for an outright long option: cash premium = filled contracts × fill price × multiplier. Then add fees and compare the result with the broker's cash activity. If the numbers disagree, keep both records and investigate the contract, quantity, multiplier, and fee line instead of silently editing the journal.

Append every material event to the same record: add, reduce, roll, exercise, assignment, expiration, corporate-action adjustment, or broker liquidation. Note the remaining quantity and the resulting stock or cash position after each event. Option assignment is an account event, not merely a label on the original short trade.

Write whether the position was closed by an offsetting trade, exercised, assigned, or allowed to expire. For a spread, confirm what happened to each leg. A short option can be assigned while a long hedge remains open, and a cash-settled contract can produce a different account entry from a physically delivered contract.

Keep trade date and settlement date separate. If you transfer an account or change brokers, preserve the original confirmations and the transfer statement so the receiving account does not become the only history. A missing record is harder to reconstruct after a contract has expired or an account has closed.

The IRS publications and forms cited here are U.S.-specific. They explain common federal reporting concepts, but they do not replace current instructions, state rules, another country's rules, or advice from a qualified tax professional. Readers outside the United States should use the same evidence workflow with their local authority and broker documents.

For U.S. activity, compare the journal with the broker's Form 1099-B or substitute statement, Form 8949 records when applicable, and any Form 6781 treatment for qualifying Section 1256 contracts. IRS instructions can treat expiration, exercise, assignment, wash-sale, straddle, and cross-account situations differently from a simple sale. The journal preserves the facts needed to ask the right question; it does not decide the tax result.

Do not overwrite a broker form because a number looks surprising. Mark the discrepancy, identify the lifecycle event and source document, and keep a dated correction note. That audit trail is more useful than a clean spreadsheet that hides how a number changed.

Complete a short review after each close or expiration, then a deeper review at least monthly. Confirm that every open position has a contract identity, risk limit, current quantity, and next decision date. Group closed trades by strategy and market condition so repeated execution costs or late decisions become visible.

Use the final review to separate outcome from process. Ask whether the thesis was specific, whether the quote supported the intended size, whether the fill matched the order, whether you followed the invalidation rule, and whether settlement created the position you expected. A profitable outcome can still reveal a process failure.
