Size belongs to the subscription — one account following one strategy — not to the strategy itself. That is what lets the same signal put one contract on an evaluation and four on a funded account.
sl in the alert.Risk sizing also needs to know what a point is worth, and that is known for the listed US futures (MNQ, NQ, MES, ES, M2K, RTY, MYM, YM, MGC, GC) and for brokers that publish their instrument specifications to Tradeus. It also has to be worth it in the account's own currency: a contract priced in dollars on a EUR account, or a CFD quoted in yen on a USD account, would size a €500 risk as if it were $500. On anything like that the risk methods fall back to the signal's own size instead of guessing, and write a warning into the event log saying so. Use Signal or Fixed sizing for those symbols.
Every amount that belongs to an account — balance, P&L, risk per trade — is shown in that account's currency. Totals across accounts in different currencies are not converted: the copier shows one sum per currency, and the dashboard marks a total that mixes them.
Quantities can be fractional wherever the instrument trades that way: an alert saying 0.25 is a valid size on a crypto or CFD symbol, and sizing snaps to the instrument's own step. Futures stay whole contracts — that is simply their step.
