How To Use The Prop Firm Challenge Calculator
This calculator helps you determine the correct contract size, understand how long it may realistically take to pass a challenge, and estimate how many winning trades are typically required based on your trading performance.
The goal is to help traders approach prop firm evaluations with structure, risk control, and realistic expectations rather than rushing or over-risking accounts.
