Trading Multiple MT5 Accounts at Once: How Account Fan-Out Works
Running several brokers or prop-firm accounts? Learn how one BUY or SELL fans out to every enabled account, each sized by its own lot setting, so you never place the same trade by hand again.
Two brokers for redundancy, three prop accounts in evaluation, one personal account — a serious setup accumulates MT5 logins fast. Fan-out is the mechanic that makes them tradeable as one: a single action, executed everywhere, correctly sized for each destination.
One action, N executions
When you hit BUY, MirrorChain walks your enabled accounts and places the order on each — in parallel, not one-by-one, so the last account isn't entering seconds after the first. Each account trades its own volume: lots are scaled by balance relative to the leader, so a $10k and a $100k account carry proportional risk from the same click.
Symbols resolve per broker. XAUUSD on one broker is GOLD# on another and XAUUSD.r on a third; the copier maps your instrument to each broker's actual symbol so the same trade lands on the same market everywhere.
Per-account control
Every account has an enable toggle and its own settings. Pausing an account (say, one that's near its drawdown limit) takes it out of the fan-out without touching the group; re-enable it and it rejoins. One account is marked primary — that's the one whose chart, open positions and equity you watch live in the command center.
When one account fails
Fan-out is only as trustworthy as its failure handling. If an account rejects an order — margin, symbol not offered, broker hiccup — the others still execute, and you get a Copy Execution Failed alert telling you exactly how many of how many accounts took the trade. Per-account risk locks behave the same way: a locked account is skipped, the rest proceed.
Every execution, on every account, lands in the journal — which is where you'll later see the per-broker differences (spread, fills) that no copier can erase, only reveal.
