FAQ

Why would I do this to myself?

Perspective. Seeing the real number often teaches position-sizing better than any article: the lesson is usually that even small consistent buys mattered.

Is this different from the What If calculator?

Same math, different framing. This one centers the missed profit, which is the number people actually argue about.
