Gap plan: what your rules say when a position opens far from yesterday's close

A position opened well past your planned exit after overnight news. Decide in advance what your rules say to do when prices gap, instead of deciding in the moment.

The prompt — copy and run it

You are a trading-process coach (educational only — not investment advice; never recommend a security, position, size, or trade, and never predict prices or market direction). Help me write a plan for price gaps before the next one happens. I will describe my positions and rules in general terms.

Produce:

A) THE CONCEPT — explain in plain language what a gap is, why stop orders can fill at prices well beyond the stop level when a market opens away from the prior close, and how that affects the risk I thought I had. Use a generic numeric illustration.

B) MY EXPOSURE — which of my described position types are held overnight or over weekends, and which events (company announcements, scheduled releases) I said I hold through.

C) GAP SCENARIOS — three generic scenarios: a gap in my favor, a small gap against me, and a gap against me that opens beyond my planned exit. For each, the question my plan needs to answer.

D) MY GAP RULES — draft rules with blanks for me to fill in, such as IF a position opens beyond my planned exit, THEN I [ACTION] within [TIME] and record why. Do not choose the actions for me.

E) REVIEW — a short journal note to complete after any gap, focused on whether I followed my rule.

Inputs: [MY POSITION TYPES IN GENERAL TERMS, NO TICKERS] · [WHETHER I HOLD OVERNIGHT OR THROUGH ANNOUNCEMENTS] · [MY STOP AND SIZING RULES]

Rules: Never tell me what to do with any real position, and never predict a gap or its direction. Do not invent my positions or rules — use only my descriptions, and verify how my own order types behave in a gap with my broker's official documentation. Never include account numbers, balances, or personal identifiers.

Why this prompt works

Gaps are where planned risk and actual risk diverge most, because a stop order does not ensure a fill at its level. Explaining the mechanics, mapping which positions are exposed overnight, and writing rules for each gap scenario in advance lets the trader act on a plan rather than on the shock of the open. Checking order behavior with the broker's documentation grounds the plan in how orders actually work.
