MetaTrader 4 and MetaTrader 5 are still the terminals most prop firm traders first learn on, and many funded accounts are still issued on them. If you run several of those accounts, the same trade has to reach every one of them at the same price, and entering it by hand across five terminals is where fills drift apart and rules get missed.
There are two ways to mirror one MetaTrader trade to many accounts. The older way runs an Expert Advisor copier inside the terminal, hosted on a VPS. The newer way connects over the broker API from the cloud. This article covers how each mechanism works, where the EA approach breaks, and what changes when your accounts span MetaTrader and the platforms that are not MetaTrader.
Quick Answer
MetaTrader copy trading mirrors one master trade to every connected MT4 or MT5 account. The older method runs an Expert Advisor copier on a VPS; a cloud copier connects over the broker API instead, runs whether your machine is on or off, and reaches non-MetaTrader platforms an EA cannot. Trada copies MT4 and MT5 like-for-like — Forex to Forex — and enforces the per-account risk thresholds you configure.
Why MetaTrader Still Anchors Prop Firm Trading
MetaTrader 4 shipped in 2005 and became the default retail forex terminal; MetaTrader 5 extended it with more order types and a different accounting model. Between them they carry a large share of the funded-account market, so most traders evaluating a trade copier start with an MT4 or MT5 account as the master.
The complication is that MetaTrader is no longer the whole picture. As of 2026, many forex prop firms have moved their accounts to DXTrade or TradeLocker — verify the current platform on each firm's site — which means a copier that only speaks MetaTrader covers part of your setup and not the rest. A trader might hold an MT5 funded account at one firm and a DXTrade account at another, and a MetaTrader-only tool cannot connect the second one at all. That constraint shapes the rest of this article and is the main filter in choosing the best trade copier for prop firms.
The Expert Advisor and VPS Approach
An Expert Advisor is an MQL program that runs inside a MetaTrader terminal. A copier EA reads open and closed positions on the master terminal and writes matching orders into each receiver terminal, usually through a local file bridge, a DLL, or shared global variables between terminals on the same machine.
That design has a hard requirement: every terminal in the chain has to be open and running for a trade to propagate. Close the master terminal, or let the machine sleep, and copying stops. To keep the terminals up around the clock, traders rent a VPS and run the whole stack there. The multi-account setup without a VPS piece covers the maintenance that comes with hosting terminals this way — updates, reconnects, and the cost of a machine that has to never go down.
The second limit is reach. An EA runs inside MetaTrader, so it can only talk to other MetaTrader terminals. DXTrade, TradeLocker, and cTrader are not MetaTrader and do not run MQL, so an EA copier has no path to them. For a MetaTrader-only trader that is fine; for anyone whose funded accounts span both, it is a wall.
How a Cloud Copier Connects to MetaTrader
A cloud copier removes the terminal from the path. It connects to the broker's MetaTrader server over an API and runs on hosted infrastructure, so there is no EA to load, no terminal to keep open, and no VPS to maintain. A trade on the master account propagates to every receiver in real time whether your computer is on or off.
Because the connection is an API rather than an in-terminal program, the same copier can connect to platforms that are not MetaTrader. Trada connects MT4, MT5, cTrader, TradeLocker, DXTrade, MatchTrader, NinjaTrader, Rithmic, and DXFeed over their respective APIs. The comparison below is between the two mechanisms, not two products.
Copying MT4 to MT5 and Beyond MetaTrader
Trada copies like-for-like: Forex to Forex, Futures to Futures. Within MetaTrader that covers MT4 to MT5, MT5 to MT4, and either one to another MT account, as long as the instrument on the master exists on the receiver. The copier mirrors the position; it does not translate one asset class into another.
The same rule extends past MetaTrader. An MT5 master can copy to a DXTrade receiver, or a TradeLocker master to an MT4 receiver, because each connection is an API the copier speaks natively. For a prop firm trader that is the practical difference: one master strategy reaches every funded account regardless of the terminal each firm issued, and the setup guide for prop firm accounts walks through connecting a mixed set end to end.
Position Sizing Across MetaTrader Accounts
Funded accounts rarely share a balance, so copying the master's raw lot size to all of them puts a different percentage of risk on each. Trada offers three sizing modes per receiver.
Percent-of-balance is the mode that keeps risk consistent when account sizes differ, which is the usual case across firms. The detail on how each mode behaves at the edges — rounding to the receiver's minimum lot, brokers with different step sizes — is in the note on trade copier lot sizing.
Per-Account Risk on Funded MetaTrader Accounts
Every funded MetaTrader account carries its own limits, and the copier will replicate a losing trade into an account that is already near its threshold unless you tell it not to. Trada attaches two thresholds to each receiver: a Daily loss threshold and a Max Account Loss threshold. When either is breached, the action you chose for that account fires automatically — notify, stop the copier, or flatten the account.
Setting the action to stop or flatten, rather than notify only, is what makes the threshold protective. A notification arrives while the position is still open; a stop or flatten set below the firm's published limit halts further copying before the account reaches it. Each receiver holds its own thresholds, so an MT5 account at one firm and an MT4 account at another do not share settings and do not interfere.
Trada enforces the thresholds you configure. It does not carry built-in knowledge of any firm's specific rules — daily loss percentages, Max Account Loss, reset times, restricted instruments — so you set those values yourself and confirm them against the firm's current terms before each account goes live.
MT4 and MT5 Differences That Affect Copying
MT4 and MT5 are not identical terminals, and two differences matter when trades cross between them. MT4 accounts are hedging by default — you can hold long and short positions in the same symbol at once — while MT5 supports both netting, where opposing orders offset into a single position, and hedging depending on how the account is configured. Copying between the two works, but a hedged set of MT4 positions maps differently onto a netting MT5 account, so confirm the receiver's accounting model matches what your strategy expects. Consult the MetaQuotes documentation for how each mode behaves, and verify on their site as of 2026.
The second difference is symbol naming. Brokers label the same instrument differently across servers — EURUSD on one, EURUSD.r or EURUSD.pro on another — and a copier matches the instrument by the name each broker exposes. When you connect a MetaTrader account, check that the master's symbols resolve to the intended pair on each receiver rather than assuming the names are identical.
Journaling and Reporting Across Accounts
Once trades are copying across several MetaTrader accounts, the record of them is spread across as many terminals. Trada's trading journal auto-captures every fill from the connected accounts, so the entry, exit, size, and result are logged without you typing them in. You annotate each trade after the fact and filter the history by strategy, session, symbol, or account.
Reporting consolidates every connected account into one performance record with a health score, which is the view that tells you whether a strategy is holding up across accounts or whether one account is dragging. The execution data is read-only — you never re-key it from a terminal — which removes the spreadsheet that usually grows alongside a multi-account MetaTrader setup.
