Capital is strategic inventory
Every position consumes risk capacity. When too much is committed to one idea, future opportunities become irrelevant because the account can no longer respond.
Sizing should begin with the distance to invalidation, not with a desired profit amount.
Survival compounds
A small controlled loss preserves optionality. A large uncontrolled loss forces emotional decisions and may require disproportionate gains merely to recover.
Professional discipline is visible in the losses a trader refuses to let grow.
