How to size vs trailing DD → Pass Estimator →

Futures point values shown are standard CME contract specs; for forex/CFD enter your broker's value per point. This rounds down to whole contracts. A drawdown buffer is small — risking a large % of it leaves no room for a losing run. Educational only, not financial advice; confirm contract specs and prop-firm rules directly.
