Questions traders ask

Why use a position size calculator before replay practice?

It trains the habit of turning a setup idea into a bounded risk decision. That same discipline carries over when you eventually move back to live execution.

Does this calculator work for crypto, forex, and gold?

Yes. The calculator keeps the core math the same and changes the position display so the output feels natural for crypto, forex, and gold planning.
