Brokers name the same instrument differently: the chart sends BTCUSDT, one broker lists BTCUSD, another NAS100 as US100, a third a share as AAPL.US. Before any order leaves, Tradeus translates the signal's symbol into each account's own name — separately for every follower of a copy group and every account following a strategy.
BTCUSDT → BTCUSD), the usual index names (NAS100 / US100 / USTEC) and a suffixed share (AAPL → AAPL.US).AAPL.US and AAPL.DE), that account is skipped and the event log names the account and the symbol it lacks. Nothing is sent to the broker. The other accounts trade as usual.To fix it, open the account's mapping — the ⇄ button beside a follower on Trade Copier, or Symbol mapping in a strategy subscription's settings — and add a line: what the signal sends on the left, what this account calls it on the right. A mapping belongs to the account, so it applies to every group and strategy that account trades in. Exits use the same translation.
Sizing follows the translated instrument: a CFD that happens to be called ES is sized by its broker's lot size, not by the CME contract of the same name.
