Can You Copy Trades From MT4 to MT5? Here's How

MarketSync can't mirror trades directly between MT4 and MT5, but it can copy the same Telegram signal source to both platforms independently — here's how to set that up correctly.

The honest answer is: not directly. There's no mechanism that reads a trade opened on an MT4 terminal and mirrors it onto an MT5 account, or the other way round. The two platforms don't talk to each other, and no third-party tool changes that fact — anyone telling you otherwise is describing something else.

What people usually mean when they search for this is simpler and entirely achievable: they've got a Telegram channel or signal provider they follow, and they want the same trades to land on both an MT4 account and an MT5 account — often because one is a personal broker account and the other is a prop firm's funded MT5 account. That's a solved problem, just not the one the phrase "MT4 to MT5 copier" implies.

This article explains how that actually works with MarketSync: attaching one Telegram source to two separate accounts, one on each platform, so both copy independently. It covers the account connection steps, the symbol suffix mismatches that trip people up (XAUUSD vs XAUUSD.m being the classic one), how to run different risk settings on each side, and how to check the logs afterwards to confirm both accounts actually did what you configured.

Why "MT4 to MT5" Usually Means Something Different Than You Think

MarketSync's only source of trade signals is Telegram. It parses the text of a signal message — symbol, direction, entry, stop loss, take profit — and places the corresponding trade on whichever MetaTrader accounts you've attached that source to. It does not, and cannot, read positions off an MT4 terminal and replicate them onto an MT5 terminal. There's no account-to-account bridge sitting behind the scenes.

So "copying trades from MT4 to MT5" in practice means this: you take one Telegram channel, attach it to an MT4 account and separately to an MT5 account, and each account copies that same channel's signals on its own. The MT4 account isn't copying the MT5 account, and vice versa — both are independently following the same upstream source. The effect looks like cross-platform copying because both accounts end up with matching trades, but the mechanism is Telegram-to-account, done twice, not account-to-account.

This distinction matters before you start setting anything up, because it shapes what you should expect. There's no synchronisation of existing open positions or trade history between the two accounts — if your MT4 account already has trades open when you attach the MT5 account, those won't appear on the MT5 side. Only signals received after both accounts are connected and attached to the source will be copied to both.

How MarketSync Copies the Same Signal to Both an MT4 and an MT5 Account

Here's the practical scenario this usually applies to: you run a personal MT4 account with your own broker, and separately hold an MT5 account that's part of a prop firm's funded programme. You follow a gold and forex signals channel on Telegram and want both accounts to take the same trades — the MT4 account because it's your own capital, the MT5 account because that's where the funded challenge or live payout account sits.

To do this, you connect both accounts to MarketSync, then attach the same Telegram source to each one individually. From that point on, when a signal arrives — say a XAUUSD sell with a defined stop and take profit — both the MT4 and MT5 accounts receive it and open their own trade according to their own copy settings. Neither account is aware of the other. If you disconnect the MT4 side tomorrow, the MT5 side keeps copying exactly as before.

This is the full extent of MT4-to-MT5 copy trading as it exists today: one signal source, two independently configured destinations, each on its native platform.

Connecting Both Accounts (Trading Password and Broker Server)

Both the MT4 and the MT5 account need to be connected before either can copy anything. The connection process is the same shape for both platforms, though the details differ slightly:

• Trading password, not investor password. MarketSync needs to place trades on your behalf, which means it requires the account's trading (read-write) password. The investor password, which only grants read-only access, won't work for a connection intended to execute trades.
• Exact broker server. Every broker runs multiple servers (live, demo, sometimes region-specific variants), and MetaTrader accounts are tied to a specific one. When connecting, you search for and select the precise server your account sits on — getting this wrong, even by a similar-looking name, means the connection won't authenticate.
• Repeat for the second platform. The MT4 account and the MT5 account are set up as two separate connections, each going through this same password-and-server step. MarketSync treats each connected account as either MT4 or MT5 — there's no single connection that covers both.

If you're not sure which server your prop firm's MT5 account uses, check the account details they issued when you opened the funded account — the server name is usually listed alongside the login number and password.

Purchasing a Second Account Slot to Pair MT4 and MT5

A base plan includes one connected MT4 or MT5 account. Pairing a personal MT4 broker account with an MT5 funded account means you're connecting two accounts total, so the second one requires purchasing an extra account slot before its connect form becomes available.

This is worth knowing before you start, because the workflow is: connect the first account, attach your Telegram source, confirm it's working, then add the slot for the second account and repeat the connection and attachment steps for the other platform. There's no way to run both an MT4 and an MT5 account under a single included slot — each connected account counts individually, regardless of which platform it's on.

Handling Symbol Suffix Differences Between MT4 and MT5

This is the single most common thing that quietly breaks cross-platform copying, and it has nothing to do with any software layer — it's a broker naming convention issue that exists between platforms and even between account types at the same broker. Gold is the classic example: your MT4 broker might list it as XAUUSD, while your MT5 broker (or the same broker's MT5 offering) lists it as XAUUSD.m, or with some other suffix such as .a, _i, or a numeric tag. Forex majors are usually consistent across the two, but gold, silver, and indices are where suffixes most often diverge.

A trade can only open correctly on an account if the symbol actually exists on that account's broker under the name being used. If a signal says "BUY XAUUSD" and your MT5 account's broker only lists that instrument as XAUUSD.m, there's a genuine naming mismatch to resolve before that account can trade it — and this is something to check per account, not something that fixes itself once one side is working.

Practical steps to get ahead of it:

• Open each connected account's symbol list (or Market Watch in the terminal itself) and note the exact spelling, including suffix, for every instrument your signal source trades — gold first, since it's the most common offender.
• Compare the MT4 symbol name against the MT5 symbol name for the same instrument, account by account, rather than assuming they match because they did on a different broker.
• Where an account's broker uses a suffixed name, confirm with that broker whether the base name is still recognised for trading, or whether the suffixed version is the only one that will execute.
• Re-check this whenever you switch broker, add a new account, or a broker changes its symbol naming — suffixes aren't fixed forever.

Getting this wrong is the most reliable way to end up with one account trading correctly while the other silently does nothing, with no obvious error to point you at the cause. The next two sections cover how to catch that before and after it happens.

Configuring Independent Lot Sizing and Take-Profit Modes Per Account

Because each connected account has its own independent copy settings, there's no requirement that your MT4 and MT5 destinations behave identically — and often they shouldn't. A personal MT4 account might warrant a fixed lot size you're comfortable with regardless of balance swings. A prop firm MT5 account, on the other hand, might need percentage-based risk sizing to stay within the firm's drawdown rules as the account balance changes.

Take a concrete comparison: the same Telegram source fires a EURUSD buy signal.

Both accounts receive the same underlying signal, but the MT4 side opens a flat 0.10 lots regardless of balance, while the MT5 side calculates its lot size fresh each time based on 1% risk against the account's current equity — meaning the two accounts can end up with quite different position sizes for the identical trade. This is done through per-source overrides: settings applied specifically to how that Telegram source behaves on that particular account, without needing to touch the source itself or affect any other account attached to it.

This flexibility is the actual value of running one source into two platforms — you're not forcing a one-size-fits-all lot size across accounts with very different risk profiles and rules.

Testing the Setup Before It Goes Live

Once both accounts are connected, the source is attached to each, symbol names have been checked, and per-account risk settings are configured, it's worth confirming everything behaves as expected before a live signal puts real money on the line.

The Signal Simulator at /backtest does this. You can load the copy settings from either your connected MT4 account, your connected MT5 account, or a saved Config Profile, and then feed in a sample signal to see how it would be handled under those settings — the lot size that would be calculated and how the take-profit mode would apply, without placing an actual trade.

A sensible way to use this before going live on both platforms:

1. Load the MT4 account's settings into the simulator and run a sample gold signal through it. Check the lot size and take-profit handling match what you configured.
2. Load the MT5 account's settings and run the same sample signal. Check the same things for that account's settings.
3. Compare the two outputs side by side. If either one looks off — an unexpected lot size, or a take-profit mode not applying as intended — fix the setting and re-run before switching the account live.

This won't tell you whether a broker-side symbol suffix is correctly matched, since that depends on what the broker actually lists rather than on copy settings — that's still worth confirming separately in each account's Market Watch, as covered above. But it will catch most lot sizing and take-profit misconfigurations before they turn into an unexpected trade on a real account.

Verifying a Cross-Platform Copy Executed Correctly in the Logs

Once both accounts are live, the way to confirm everything is working as intended is the logs. When a signal comes through and both the MT4 and MT5 accounts act on it, each account produces its own log entry, and comparing them tells you whether the setup is behaving correctly.

For a single signal, check both accounts' logs for:

• Timestamp. Both entries should be close together, reflecting that the signal reached both accounts at roughly the same time. They won't be identical to the millisecond — execution speed depends on each broker and account, and the two platforms won't always process at the same pace — but a large gap suggests something delayed one side.
• Symbol. The MT4 log should show the symbol name as your source trades it, and the MT5 log should show that account's own broker symbol. If the MT5 log shows a rejected or missing entry where you expected a trade, that points straight back to a symbol naming mismatch.
• Lot size. The MT4 entry should match your fixed lot configuration; the MT5 entry should reflect the percentage-risk calculation for that account's balance at the time. If the MT5 lot size looks wrong for the balance, check the risk percentage setting rather than assuming a fault elsewhere.

Doing this check after the first few live signals, rather than waiting until something looks off, is the quickest way to catch a misconfiguration early — a symbol mismatch or an unintended lot sizing setting is far easier to fix before it's affected a dozen trades than after.

Frequently asked questions

Can MarketSync copy trades directly from an MT4 terminal to an MT5 terminal?

No. MarketSync only copies signals from Telegram onto MetaTrader accounts — it doesn't read trades from one MT terminal and mirror them onto another. Cross-platform copying works by attaching the same Telegram source to both an MT4 and an MT5 account, so each copies the signal independently.

Do I need the investor password to connect my MT4 or MT5 account?

No, you need the trading password. The investor password only grants read-only access, which isn't enough for placing trades, so connections for either platform require the full trading password along with the correct broker server.

Can I attach the same Telegram channel to more than two accounts?

Yes, a Telegram source can be attached to multiple accounts at once — it isn't limited to a single MT4-and-MT5 pair. Each additional account still needs its own connection and, beyond the plan's included account, its own purchased slot.

Does copying happen at the same speed on MT4 and MT5 destinations?

Signals are typically processed within milliseconds to seconds of the Telegram message arriving, but the exact speed on each account depends on that account's broker execution and the complexity of the parsed signal. There's no guarantee that an MT4 and an MT5 destination fed by the same source will execute at identical speed or with identical outcomes.

Can I pair a personal MT4 broker account with a prop firm MT5 account?

Yes, this is a common setup — you connect the MT5 prop account the same way as any other MT5 account, using its broker server, account number, and trading password. There's no special integration for prop firm accounts beyond the standard MT5 connection process, and no guaranteed compatibility beyond that.

Do I need a VPS to run linked MT4 and MT5 accounts?

No. MarketSync runs entirely in the cloud, so neither the MT4 nor the MT5 account needs a VPS or any installed software for signals to be copied.

What happens if I don't fix the symbol suffix mismatch between MT4 and MT5?

The affected account is likely to fail to open the trade at all, since the broker's actual symbol name won't match what the signal specifies. This often goes unnoticed until you check the logs, because one account trades correctly while the other quietly does nothing.

Getting Your Cross-Platform Setup Running

If you're pairing a personal MT4 account with an MT5 account, whether that's a second broker account or a prop firm's funded account, the order that works best is: connect both accounts with their trading passwords and correct servers, attach your Telegram source to each, check symbol names against each broker's actual listing (gold first, since that's where suffixes most often differ), then set independent lot sizing and take-profit rules that suit each account's purpose. Run a sample signal through the Signal Simulator at /backtest for both accounts before going live, and check the logs after the first few real signals to confirm timestamps, symbols, and lot sizes look right on both sides.

Trading carries risk, and copying a signal to two accounts doesn't change that — losses are possible on either or both destinations regardless of how carefully the setup is configured. Getting the mechanics right just means you're seeing the outcome the settings were actually designed to produce, rather than a symbol mismatch or a misconfigured lot size doing something you didn't intend.
