Calculate the ideal lot size for your trades based on your account balance and risk percentage. Master position sizing for professional risk management.
Work out a lot size from your balance, risk and stop loss.
Position sizing is the most important skill in professional trading. Our lot size calculator shows exactly how large a position you should take based on your account balance and how much you are willing to risk.
Many traders fail because they size positions by feel. Enter your balance, risk percentage and stop loss in pips, and the calculator gives you a recommended lot size so a run of losses cannot wipe out your account.
To pass a prop firm challenge you must stay inside strict daily and total drawdown limits. Never risking more than a small share of your capital on one trade is how you stay within the rules and prove your consistency.
Always calculate your risk before you look at your potential reward. Define the risk on every trade so your position size always fits your trading plan.
