Tell it your balance, the percent you are willing to risk, and your stop loss. It returns the one number that keeps a single losing trade from costing more than you planned.
No sign-up. No signals. Just clean risk maths.
Start from the percent you are comfortable losing. The lot size follows from that, not the other way around.
Pick your pair and account currency. It handles the pip-value conversion so the number is right, not rounded guesswork.
Open it, type four things, get your size. Fast enough to use right before you place the order.
This calculator was built for traders who treat risk as the first decision, not an afterthought. Before you enter a position it tells you exactly how many lots to trade, so a single stop-out never costs more than you chose to put on the line.
There are no signals here, no promises about where the market is going, and nothing to sign up for. Just the calm arithmetic that keeps an account alive long enough for a real edge to play out. Enter your balance, your risk percent, and your stop, and trade the size the maths gives you.
