An MT4 to MT4 trade copier is the simplest way to run one MT4 account's trades on several others, for example from your own broker account to a prop firm challenge, or from one funded account to the rest. Heron Copier watches the master and repeats every open, modification, partial close and close on each slave.
Because MT4 is hedging only on both sides, each master ticket maps to exactly one slave ticket, and opposite trades on the same symbol stay separate. What usually differs is the broker. One may quote EURUSD while another uses EURUSD.m or adds .pro to every symbol, so set a suffix or aliases on the slave. Account sizes differ too. The default Equity-to-Equity sizing keeps each slave's risk in proportion to the master, and per-symbol lot caps stop oversized trades. If several EAs trade the master, the magic number filter lets each slave copy only some of them.
It runs in the Heron Copier cloud, with no VPS and nothing to install, or locally on your own VPS. Every paid license includes both.
How to set up MT4 to MT4 copying
- Add your MT4 account as the master in the dashboard. Connect it with your MT4 account number, password and broker server.
- Add your MT4 account as the slave and pick the master it copies from. Connect it with your MT4 account number, password and broker server.
- Choose one of the six volume sizing methods for the slave and, if the brokers name symbols differently, add a symbol suffix or aliases.
- Launch. Cloud accounts are usually online in under 60 seconds, and the dashboard shows every copied trade, balance and position live.
About MT4
MetaTrader 4 came out in 2005 and is still the most common retail forex platform. Brokers and prop firms keep offering it because of its large library of Expert Advisors and indicators written in MQL4.
For everything else about the platform, see the MT4 Trade Copier page.

Things to check before you start
- Each slave has its own volume sizing, so accounts of different sizes can copy the same trades. The default, Equity-to-Equity, keeps the risk of every slave in proportion to the master.
- Two MT4 brokers can still name symbols differently. Set a suffix or aliases on the slave if the names don't match.
- Turn on Position Resync if you want the MT4 slave to check that every copied position is still open on the master.
- Trades opened by your EAs are copied too. Use the magic number whitelist or blacklist on the slave to copy only some EAs.
- MT4 brokers often add suffixes to symbol names. Set a symbol suffix or symbol aliases on the slave, or let auto symbol mapping find the match.
Frequently asked questions
Can one MT4 master copy to several MT4 accounts?
Yes. Add as many MT4 slaves as you need, each with its own volume sizing, symbol mapping and risk limits. In the cloud every account uses one cloud seat, and the local version has no account limit.
Can the MT4 accounts be at different brokers or prop firms?
Yes. That is the most common setup. Symbol suffixes and aliases handle different symbol names, and each slave has its own volume sizing.
What happens if a trade fails to copy?
Turn on failed trade copy notifications to get an e-mail alert. The account logs in the dashboard also show the reason, for example a symbol that doesn't exist on the slave or a size below the minimum.
Is there a free trial?
Yes, 7 days with 2 cloud accounts. During the trial a slave copies every trade at a fixed 0.01 lot; a paid license unlocks the other sizing methods.
