MT4 to MT5 trade copier: Trade on MT4. Copy to MT5. Or the other way round.
Algo Trader Tools is an MT4 to MT5 trade copier that runs in our cloud. It copies every trade between MetaTrader 4 and MetaTrader 5 accounts, at one broker or across brokers, and handles what differs between them: symbol names, contract sizes, lot steps and order types. No Expert Advisor, no VPS.
From $19 a month for 2 accounts: one MT4 master and one MT5 follower. See pricing
| Topic | Master | Follower |
|---|---|---|
| Account | MT4 at broker A | MT5 at broker B |
| Symbol | XAUUSD | GOLD.m |
| Contract size | 100 oz a lot | 10 oz a lot |
| Trade | Buy 1.00 lot | Buy 10.00 lots |
| Stop loss, take profit | Set | Same prices |
What the copier handles
Where MT4 and MT5 differ, and how each copy fits.
Copying the same lot size on the same symbol name works only when both accounts are alike. Between MT4 and MT5, and between brokers, they rarely are.
Symbol names
Brokers add suffixes such as EURUSD.m or US30.cash, and some rename instruments outright: GOLD instead of XAUUSD. Each master symbol is matched to the follower broker’s name. Anything ambiguous is skipped, never guessed, and you map it once.
Contract sizes
Gold can be 100 oz a lot at one broker and 10 oz at another. The copier evens that out, so 1.00 lot of 100 oz becomes 10.00 lots of 10 oz, and then applies your sizing rule.
Lot steps and minimums
Each copy is rounded down to the follower broker’s lot step and capped at its largest lot. If it comes out below the smallest lot, the follower trades the minimum or skips the trade, as you choose.
Account sizes
A 10K account and a 200K account can take the same trade at the same risk. Balance ratio, equity ratio or risk per trade sizes each copy to its own account, and you can cap the largest lot.
Order types
Pending orders are copied when they fill, or placed on the follower as pending orders that move, cancel and expire with the master’s. MT4 has no stop-limit orders, so those reach an MT4 follower when they fill.
Stops and partial closes
Stop loss and take profit are copied at the master’s prices, along with every later change. When the master closes part of a position, each copy closes the same share.
Setup
Set it up in four steps.
Connect the MT4 master
With its account number, broker server and read-only investor password. Nothing is installed in MetaTrader, and an EA keeps trading where it runs now.
Connect the MT5 followers
With their trading passwords, at the same broker or any other. Each one takes a slot on your plan.
Choose how each follower sizes its trades
Multiplier, fixed lot, balance ratio, equity ratio or risk per trade, with contract sizes evened out. Map any symbol that doesn’t match by itself.
Check the first copy
Place a small trade on the master, on demo accounts first if you like, and watch it appear in the copier’s activity with its size and symbol.
The API does the same, step by step in the docs.
Before you start
- Each MT5 account is a hedging account. Your broker can tell you which type you have.
- Automated trading is allowed on each follower. Brokers can switch it off for a single account, and such an account can’t follow.
- The follower’s broker offers the instruments you trade, under whatever name.
- If a follower is a prop firm account, your firm allows a copier.
Symbol names
GOLD or XAUUSD, US30 or DJ30: matched for you.
Each master symbol is matched to the follower broker's list in this order: your own mapping, the same name, the same name without the broker's extra characters, then the known aliases. When several fit, the plain name wins, so US500 beats US500m.
Extra characters cover names such as EURUSD.m, EURUSDpro, US30.cash, NAS100-ECN and #XAUUSD.

Common setups
Three ways traders use it.
Your EA on MT4, your account on MT5
Connect the MT4 account with its read-only investor password. Your Expert Advisor keeps trading where it runs now, and every trade it places is copied to your MT5 accounts.
An MT5 strategy, MT4 accounts too
Copy from an MT5 master to accounts at brokers or prop firms that still run MT4. Each follower has its own lot sizing, so different account sizes take the same risk.
Several brokers at once
One master, followers at different brokers on MT4 and MT5. Symbol names and contract sizes are matched for each follower on its own.

Instead of an Expert Advisor
No EA in either terminal.
Many MT4 to MT5 copiers are Expert Advisors that run in both terminals. Algo Trader Tools reads and places the trades from our cloud.

Can I copy from MT5 to MT4 as well?
Yes. Copying works in both directions, MT4 to MT5 and MT5 to MT4, and between two MT4 or two MT5 accounts. A copier can mix them: one master with followers on both platforms.
Does it work between different brokers?
Yes. Each follower can be at any broker that offers MT4 or MT5. Symbol names and contract sizes are matched per follower, so a master at one broker and followers at three others each get the right instrument at the right size.
Do I need to install anything on the master?
No. Your accounts run in our cloud, and the master only has to be read. Connect it with its investor password, and an EA or your own trading keeps running wherever it runs now.
What happens if a trade can't be copied?
It's skipped for that follower, and the skip shows in the copier's activity with the reason: for example a symbol the follower's broker doesn't have under any matching name, a size below the broker's smallest lot when you chose to skip those, or a master trade without a stop loss when the follower sizes by risk. Map a missing symbol once in the follower's settings, and the next trade copies.
How fast are copies?
In our published test of two MT5 accounts, a median of 46 ms from the master's fill to the copy's. Most of that time is the brokers filling the orders.
Can I copy into prop firm accounts on MT5?
Yes, where your firm allows a copier. Our prop firm page lists what to check with your firm first.
What does it cost?
Every account in a copier takes one slot, master or follower. Starter is $19 a month for 2 accounts, one MT4 master and one MT5 follower. See pricing for more accounts.
