Dollar-risk-first sizing for forex, done for you. Set the risk you'll accept and the size of your stop, and it returns the position size in lots that makes that stop equal your risk — with the pip value converted into your account currency.
Decide your risk first — a fixed % of the account (or a flat amount). Place the stop where the idea is invalid (the swept level plus a buffer), read its size in pips off your chart, and let the calculator set the lots. Never widen the stop to fit a size you want. If even one micro-lot risks more than your budget, tighten the stop or skip the trade.
Your inputs are saved on this device. Cross-currency conversion uses live ECB reference rates; if they can't load, the conversion rate becomes editable so the tool still works. The math: lots = risk ÷ (stop in pips × pip value per lot), pip value taken in your account currency and rounded down to 0.01 lots.
A pip is the standard price increment: 0.0001 on most pairs, 0.01 on JPY pairs. On one standard lot (100,000 units), one pip is worth 10 units of the quote currency (1,000 on JPY pairs). If the quote currency isn't your account currency, that value is converted at the current exchange rate — which is why the account-currency selector matters.
| Lot | Units | Pip value (non-JPY, quote ccy) |
|---|---|---|
| Standard | 100,000 | 10 / pip |
| Mini | 10,000 | 1 / pip |
| Micro | 1,000 | 0.10 / pip |
Sizing in 0.01-lot (micro) steps is what lets you risk a precise amount and scale out granularly — the same idea as trading micro futures.
