How to copy trades between MetaTrader 4 and MetaTrader 5

What differs between MT4 and MT5

On top of that, every broker names its symbols, sizes its contracts and sets its volume steps in its own way. Those differences exist between two MT4 brokers as well, but they decide whether a copy comes out right when the master and the follower are on different platforms.

What the copier handles for you

• Partial closes on MT4. The new ticket MT4 creates for the remainder is recognised as the same trade, so the follower keeps following it and a later close still finds its copy.
• Every change, not only the open. Stop loss and take profit changes, pending orders (placed, moved, deleted, filled), partial closes and closes are repeated on the follower. The features page lists them all.
• Different lot sizes. Contract sizes and account currencies differ between brokers, so each follower sizes its own copy. See how lot sizes are calculated.
• Different symbol names. EURUSD, EURUSD.m and EURUSDm are matched automatically. See symbol names across brokers.
• A dropped connection. After a reconnect, each follower is compared with its master and anything that was missed is repaired, without a second copy of a trade that is already there.

Set up a link between the two platforms

1. 1Sign up for the free SnapCopier beta.
2. 2Add the master account. Pick the platform, search for the broker’s server and enter the login. A read-only investor password is enough for a master.
3. 3Add the follower account, on the other platform if you like. Or share an invite link, so the follower connects their own account and you never see their password.
4. 4Choose how the follower sizes its copies. The settings show a sample calculation before anything is copied.
5. 5Open a small trade on the master and watch the copy appear in the log, with the time it took and the reason for anything that was skipped.

The steps are the same for MT5 to MT4: the platform is a property of each account, not of the link.

Limits to know

• MT5 netting accounts cannot be followers. A netting account merges trades into one position per symbol, so it cannot hold copies of separate master positions. Hedging accounts work on both platforms.
• Stop-limit orders exist only on MT5. If you copy pending orders from an MT5 master to an MT4 follower, test that case with a small order first.
• Your broker and your prop firm decide whether copying is allowed. Some firms restrict copying between accounts, so read their rules before you connect.
• Speed depends on both brokers. The copy log splits each copy’s time into our own processing, the wait for a price and the broker’s execution, so you can see where the time went.
