Enter a stop distance and your accounts. See the lot size each one would take, and what the whole set stands to lose if the stop is hit.
One alert, sized separately for every account below.
10 for most USD-quoted FX pairs. Your broker's contract specification has the exact figure.
Same signal, same stop. Only the size changes.
| Account | At risk | Lots |
|---|---|---|
| Challenge | 500.00(0.5%) | 2.50 |
| Funded | 500.00(1%) | 2.50 |
| Personal | 100.00(2%) | 0.50 |

Each account is sized to its own balance and its own risk percentage, so no single line looks alarming. The figure worth watching is the total: one stop, hit once, charged to every account at the same moment.
Traders running a challenge, a funded account and something personal usually set each percentage in isolation. This shows what those separate decisions add up to on a single trade.
The same arithmetic NexumTrader's EA uses at execution:
lots = (balance × risk%) / (stop distance × pip value per lot)The result is rounded to the broker's lot step and raised to the minimum order size where it lands below it. An account flagged min is one the minimum forced larger than the risk percentage asked for, which is worth knowing before it happens rather than after.
One honest limitation: the real EA asks MT5 for the exact loss per lot on your broker and symbol, which accounts for contract size and currency conversion. In a browser there is no terminal to ask, so the pip value is yours to supply and the output is an estimate. It is exact for the pip value you enter. How lot size is calculated covers what the EA does differently.
This calculator does by hand what NexumTrader does on every alert: take one TradingView signal and size it separately for each connected MT5 account, with per-account risk, trading windows and session rules.
