When to Cut Size, Not the Setup
Recognizing days when the chart idea is sound but conditions demand a smaller footprint.
Some sessions offer clean structure and poor conditions. Spreads widen, news sits on the calendar, or you are already halfway through a daily loss limit. Cutting the idea entirely is not always required—cutting size often is.
Conditions that call for half size
Examples include trading into a scheduled data release, opening into a gap that has not settled, or sitting on two consecutive losses. The setup can remain valid while the environment asks for a smaller footprint.
Write the rule before the session
Impulse cuts feel like weakness; pre-written size bands feel like process. Define in advance when you trade full size, half size, or not at all. Then the decision at the chart is recognition, not negotiation.
