In simple terms
To switch bias is to change the directional hypothesis—for example, from bullish to neutral or bearish. The first change is in the market interpretation.
Revision or reaction
A disciplined switch follows new evidence or a predefined invalidation. If the thesis changes with every small move, no observable rule is governing it. Recording what changed, the relevant horizon, and which prior condition failed separates learning from decision instability.
It is not yet a position flip
A bias change may lead to no entry, an exit, a reduction, or more waiting. Flipping long to short describes a possible operational reversal. Switching bias does not automatically close the current position and does not require an opposite one; orders, fills, and final net quantity remain separate facts.
