Position size

Four methods, set per account and not per strategy.

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.

Signal
Use the alert's own quantity, multiplied by a factor. Default factor is 1.
Fixed
The same number of contracts every time, whatever the alert says.
Risk amount
A fixed amount per trade in the account's own currency — dollars on a USD account, euros on a EUR one — divided by the stop distance. Needs sl in the alert.
Risk in percent
The same, as a percentage of the account balance.
Risk sizing can round to zero
A wide stop and a small risk budget produce less than one contract, and less than one contract is no trade. That appears in the event log as a rejection rather than as a fill you never got — check there before assuming the signal was lost.

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.
