Field note
Writing invalidation before you talk about entry
Entry discussions eat the clock. Starting with where the idea is wrong keeps risk management for chart-based trading ahead of hope.
In clinic rooms, the first impulse is to debate the entry candle. That debate is engaging. It is also the wrong first step if the goal is a controlled loss when the idea fails.
Invalidation is a location on the chart: a break of a swing, a failed retest, a close beyond a channel that defined the thesis. Until that location is named, “tight stop” and “wide stop” are adjectives without a reference.
A sequence we use in Session Prep Coaching:
- State the thesis in one sentence
- Mark the structure that would make the sentence false
- Measure stop distance from a realistic fill
- Size the position so that distance equals the planned R
- Only then discuss whether the entry is worth taking today
Traders who reverse steps four and five often discover that the entry they liked required an R they never intended to spend. Writing invalidation first makes that discovery happen on paper, before the open.
