Write the invalidation before you write the entry
If the failure level is vague, the size decision is already compromised.
- setups
- risk
Traders often sketch a beautiful trigger and only later ask where they are wrong. By then, the stop is chosen to fit a preferred size rather than the structure that justified the trade.
A risk-based habit flips the order: mark the level that proves the idea false, measure distance from planned entry, then decide whether that distance deserves capital today.
When invalidation is written first, many 'almost setups' simply do not clear the gate. That is the point—fewer forced trades, cleaner journals.
In our Setup Lab we refuse to discuss entry timing until the failure line is on the chart and sized against the account risk band.
