Lot Size Optimization Tips
The 1-2% Rule:
Most professional traders risk 1-2% per trade. This allows surviving losing streaks while still growing the account.
Adjust for Volatility:
Use smaller lots during high-impact news and larger lots during calm markets with clear setups.
What is a Lot Size Optimizer?
The lot size optimizer goes beyond basic position sizing by analyzing your trading statistics and showing multiple risk scenarios. It calculates the optimal lot size based on your account balance, average stop loss, win rate, and trading frequency.
This tool helps you find the sweet spot between growing your account and protecting against drawdowns. Compare different risk percentages side-by-side to see projected monthly returns and maximum potential losses.
