Open Full Calculator →With a $150K Topstep account, your daily drawdown limit is $3,000 (2%). This means if you risk 1% per trade ($1,500), you can absorb 2 consecutive losses before breaching the daily limit. At 2% risk per trade, that drops to just 1 losses.
The profit target for Phase 1 is 6% ($9,000). At 1% risk with a 1.5:1 reward-to-risk ratio, each winning trade nets $2,250. You would need approximately 16 trades with a 55% win rate to reach the target.
