MT5 to MT4 trade copier

When MT5 → MT4 makes sense

• Your strategy or prop account is on MT5, and your personal broker only offers MT4.
• You manage a master on MT5 and want to mirror it to MT4 accounts you own at other brokers.
• You trade by hand on MT5 (on the desktop or the mobile app) and want the same trades on an older MT4 account.

What MT5 can do that MT4 can't

Market orders, the four classic pending types, stops, targets, partial closes and closes all have direct MT4 equivalents, so for most manual and EA strategies the direction makes no practical difference.

FIFO and no-hedging MT4 accounts

MT4 accounts at US-regulated brokers follow FIFO: positions on a symbol must be closed in the order they were opened, and opposite positions on the same symbol are not allowed. An MT5 hedging master that holds a buy and a sell on EURUSD, or closes its second trade before its first, will see those copies rejected on a FIFO account. If your MT4 account is FIFO, set the copier's "same symbol" rule to not allow multiple positions, or pick a source that never hedges.

Symbol and contract differences

MT4 servers often use older or different names: GOLD instead of XAUUSD, DJ30 instead of US30, # or . prefixes on CFDs. The copier strips suffixes and prefixes and knows the common aliases. Contract sizes for indices and commodities can still differ between the MT5 master's broker and your MT4 broker; read indices copy trading before mirroring index lots.

Setting up an MT5 → MT4 copier

1. Add the MT5 hedging account as a source with its investor password.
2. Add each MT4 account as a target with its trading password.
3. Create one copier per MT4 account and choose sizing: risk by balance for proportional copies, lot multiplier for fixed ratios.
4. If the master uses stop-limit orders, turn off pending-order copying for those copiers.
5. Send a test trade to each copier, check History, then switch them on.
