MetaTrader 5 to MetaTrader 4 (MT5 → MT4) Copier
MirrorFlow uses MetaTrader 5 as the master (source) account and replicates every trade to MetaTrader 4 from a standalone Windows app — no NinjaTrader required. A MirrorFlow EA on the master MT5 reads your orders and another EA on the follower MT4 executes them, with the app connecting both over a local Windows channel. It keeps both MetaTrader terminals in sync with latency under 15ms, automatic symbol mapping and a one-time payment of $69.
MetaTrader 5 as the master account
Your EA or manual analysis on MT5 fires the signal; the MirrorFlow EA attached to the master MT5 captures it and the app sends it to the follower MT4, without touching your strategy or your MQL5.
Standalone app, no NinjaTrader
MirrorFlow is a Windows app with its own panel: install the app and connect only MetaTrader 5 and MetaTrader 4. It needs no NinjaTrader and no cloud servers — everything travels over a local Windows channel.
Symbol and suffix mapping
Maps EURUSD, EURUSD.m or EURUSD.raw between your source MT5 broker and destination MT4 broker, adjusting digits and point/pip value automatically.
MT5 netting or hedging → MT4 hedging
MT4 is always hedging; if your master MT5 is netting, MirrorFlow translates its net-position changes into MT4 orders, with lot multiplier, Invert Side and daily MDD/MDP limits per account.
Install the app
Download and install MirrorFlow.App on Windows. You don't need NinjaTrader: the app runs on its own.
Connect MT5 and MT4
Attach the MirrorFlow EA to a chart on the master MT5 and to a chart on the follower MT4, both with AutoTrading enabled; the app links the two terminals.
Set lot size and risk
Map each MT5 broker symbol to its MT4 equivalent and set the lot multiplier, Invert Side and MDD/MDP limits per account.
Trade on MT5
Every entry, SL, TP, trailing and partial close you execute in MetaTrader 5 is cloned instantly in MetaTrader 4.
FAQ
Can MetaTrader 5 be the master account to MetaTrader 4?
Yes. MT5 is one of the base platforms that can act as source (alongside NinjaTrader 8, MT4 and cTrader). You trade on MT5 as the master and MT4 receives the replica as the follower.
Do I need NinjaTrader to copy from MT5 to MT4?
No. MirrorFlow is a standalone Windows app: install it and connect only the platforms you use — here MetaTrader 5 and MetaTrader 4. NinjaTrader is not required.
How does it copy from MT5 to MT4 if they use different languages (MQL5 and MQL4) and different symbol suffixes?
The MirrorFlow EA on MT5 (MQL5) reads your orders and the EA on MT4 (MQL4) reproduces them; the app connects them over a local Windows channel. The mapping panel links each symbol (e.g. EURUSD.m on MT5 to EURUSD on MT4) and adjusts digits and point value.
Does it work if my MT4 account is with a prop firm?
MirrorFlow executes inside MetaTrader 4 itself, on your machine, with no cloud servers or middlemen. That said, every firm has its own rules on automation and copying between accounts, and those rules change: check your firm's rulebook before trading. MirrorFlow replicates; compliance stays with you.
How much does it cost and how many accounts can I connect?
A one-time payment of $69 for a lifetime license, with unlimited destination MT4 accounts and all future updates included.
