The checklist decides

Willpower runs out. A written rule does not, which is why the fix for impatience is written rather than felt.

A plan is a sequence

A trading plan is not a description of your style. It is the order of events that has to happen before you are allowed to enter.

Written as steps, it might read like this: a liquidity sweep, then a break of structure, then price filling the gap, then a reaction at the gap, then the entry.

A plan is the list of things that must happen, in order.

Any step missing is no trade

The gate is simple. Every step present, and the trade exists. One step missing, and it does not.
