Position sizing is the single most important habit for survival in trading.
1. Decide your risk per trade
Most professionals risk 0.5%–1% of their account per trade. On a $10,000 account, 1% is $100.
2. Measure your stop-loss distance
Place your stop where the trade idea is invalid — not where it feels comfortable. Measure the distance from entry to stop.
3. Divide
Lot size = Risk amount ÷ (Stop distance × Contract size)
Use the Risk Manager calculator in your dashboard to do this automatically.
