How this is calculated: Caliber uses MDD × 10% as the operative risk budget, not raw account size — this is the actual drawdown limit your prop firm enforces. Contracts are sized so a realistic losing streak never approaches that limit. The $210 TP / $310 SL base bracket (validated at 3 contracts in live forward testing) scales proportionally: 3× the base contracts means 3× the dollar bracket — the strategy's behaviour, win rate, and lockout frequency stay identical regardless of size.

⚠ Risk disclosure: Past forward test performance does not guarantee future results. Contract size recommendations are based on MDD × 10% as a risk-budget heuristic, not a guarantee against account breach. Always confirm your specific prop firm's drawdown rules (trailing vs static, EOD vs intraday) before sizing positions. This calculator is a planning tool, not financial advice.
