Copying Trades Between MT5 Hedging and Netting Accounts: What Breaks and How to Fix It

A trade copier moving orders between two MT5 accounts looks like a simple relay: master opens a position, follower opens the same position, scaled to size. Most of the time that is exactly what happens. But MT5 has a setting most traders never look at until something goes wrong, the account's position accounting mode, and if the master and follower are running different modes, the copier is being asked to do something that has no clean answer. This is not a bug in the copier. It is a structural difference between how the two account types represent a position, and understanding it will save you from staring at a follower account that doesn't match the master and assuming the software is broken.

Hedging vs netting: what they actually are

MT5 sets its position accounting mode at the account level, exposed programmatically as ACCOUNT_MARGIN_MODE. There are effectively two behaviors a trader deals with day to day: hedging mode and netting mode. The platform launched in 2010 with only netting accounting, and MetaQuotes added hedging accounting in a later build, commonly cited as build 1325 in 2016. Both have been standard options for years now, but which one your account runs is a broker configuration decision made at account creation, not something you toggle from a dropdown.

Hedging mode. An account in hedging mode can hold multiple positions on the same symbol at the same time, including positions in opposite directions. Each position is its own ticket with its own entry price, volume, and stop loss/take profit. You can be long 3 contracts of ES under one ticket and short 2 contracts of ES under a different ticket, simultaneously, in the same account. Closing a position means specifying that ticket's number in the trade request. You can close one ticket fully, close it partially, or close it against a specific opposing ticket using the CLOSE_BY mechanism, all without touching any other open ticket on that symbol.

Netting mode. An account in netting mode collapses all activity on a given symbol into one position. There is no second ticket to open. A new deal in the same direction as the existing position increases its size. A new deal in the opposite direction reduces the position, closes it outright if the volumes match, or reverses it to the other side if the new deal's volume exceeds what's currently open. The platform only ever shows one net line per symbol per account, and that line is the arithmetic sum of every deal executed on that symbol.

Neither mode is "correct." Netting is standard for exchange-traded instruments in MT5's exchange margin mode, and it's also the mandated model for a lot of regulated retail forex. Hedging has historically been offered mainly on retail forex/CFD-style accounts where the broker allows it. Which one you're on depends entirely on how your broker configured the account.

The case that copies cleanly: adding to a position

Start with the good news, because most copier setups between a hedging master and a netting follower work fine in practice. If the master is simply scaling into a position in one direction, netting handles it without any distortion.

Say a hedging-mode master already holds Ticket A, long 2 ES contracts. The master's strategy then opens Ticket B, long 3 more ES contracts, same symbol. On the master's hedging account, that's now two separate long tickets sitting side by side, 2 contracts and 3 contracts. A netting-mode follower copying at a 1:1 ratio doesn't need two tickets to represent this. It just ends up with a single net long position of 2 + 3 = 5 contracts.

Total exposure matches: the master's combined long exposure is 5 contracts (2 + 3), and the follower's single net position is also 5 contracts long. The internal bookkeeping is different (two tickets versus one), but the market exposure the two accounts are carrying is identical. This is the overwhelming majority of what a trend-following or scale-in strategy actually does, so if that describes your master's behavior, hedging-to-netting copying is not the landmine people sometimes assume it is.

The real break: a deliberate two-sided hedge

The problem isn't adding to a position. It's when the master intentionally holds a position in both directions on the same symbol at the same time, a genuine two-sided hedge, not a same-direction add.

Take a hedging-mode master holding Ticket A, long 4 NQ contracts, and separately, Ticket B, short 4 NQ contracts, opened deliberately as a hedge. The master's net market exposure is 4 long minus 4 short, which is 0. But that "0" is misleading if you stop there: the master has 8 contracts of gross exposure live across two tickets, each with its own entry price and its own independent stop loss. If NQ gaps, both tickets are affected differently depending on where each was entered and where each stop sits. This is a real, live risk position, not a flat account.

A netting-mode follower cannot represent this. It has exactly one line per symbol, so there is no way to hold long 4 and short 4 at once. Watch what happens if a copier maps each ticket to the follower as it arrives, in order:

• Ticket A arrives first: the follower goes long 4.
• Ticket B arrives second, as an opposite-direction deal on the same symbol. On a netting account this does not open a second position. It reduces the existing long 4 by 4, which fully closes it out. The follower ends up flat, net position 0.

The master still has two live tickets open, long 4 and short 4, 8 contracts of gross market risk and two separate P/L streams still running. The follower has nothing open at all. The master's actual two-sided exposure has been erased, not replicated, by simple arithmetic: 4 minus 4 equals 0, which is exactly what netting is built to compute. If the master later closes just the short ticket and stays long 4, the follower (already flat) has no way to correctly pick that back up in sync, because the follower's history never held a position that matched the master's structure in the first place.

Netting doesn't misrepresent a two-sided hedge by accident. It's designed to always collapse a symbol to one number, and a genuine hedge is precisely the case where that number stops describing the real position.

This is worth separating clearly from a different, non-technical restriction some traders run into: prop firms that ban a trader from holding intentional hedges across that trader's own multiple funded accounts. That's a firm trading-rule question, a policy choice by the prop firm about what counts as acceptable risk-taking on their capital, and it has nothing to do with MT5's account mode. The two topics get conflated because both involve "hedging," but one is a platform data-structure limitation and the other is a contractual rule. If you want the firm-rules side of that, it's covered separately in our piece on prop firms banning hedging across accounts; this article is strictly about what the MT5 platform itself can and cannot represent.

Partial closes: where a copier has to do its own accounting

Partial closes are the next place hedging and netting diverge, and it's subtler than the two-sided case because both accounts can end up holding the "right" total size, while only one of them can tell you how it got there.

On a hedging account, each ticket can be partially or fully closed independent of any other ticket on the symbol. On a netting account, a partial close just reduces the size of the single net position. There's no ticket-level concept to partially close, because there's no second ticket.

Here's where that matters. A hedging-mode master has two open tickets on GC: Ticket A, long 3 contracts, opened first, and Ticket B, long 2 contracts, opened second. Total: 5 long, matching a netting follower's single net position (this is the same-direction add case from earlier, so the follower is already sitting at a clean net long 5). Now the master partially closes Ticket A by 1 contract. Ticket A drops to 2 contracts, Ticket B stays at 2 contracts, for a new total of 4 (3 + 2 - 1 = 4).

On the netting follower, the broker's own record shows only one position that went from 5 contracts to 4 contracts after a partial close, 5 - 1 = 4. There is no record anywhere on that netting account saying the reduction came specifically from what had been Ticket A rather than Ticket B. The netting account's deal history is a sequence of deals against one position, full stop, it doesn't have rows for "Ticket A" and "Ticket B" the way the hedging account does.

If the copier (or the trader) later wants to know how much of the follower's remaining 4-contract position corresponds to the master's now-2-contract Ticket A versus the master's still-2-contract Ticket B, that mapping does not exist anywhere in the broker's netting-account records. It has to be tracked and maintained inside the copier's own internal state, matching deals to originating tickets as they happen, because once the netting account has processed the deal, the distinction is gone. This is a genuine software problem worth understanding when you're evaluating how a copier bridges MT5 accounts step by step, since the quality of that internal bookkeeping is exactly what determines whether your follower stays reconcilable against the master over weeks of partial closes, not just the first trade.

Trade history and P/L reporting will look structurally different

Because hedging and netting store position data in fundamentally different shapes, the trade history and per-trade P/L reports pulled from a hedging account and a netting account are not directly comparable, even when both accounts started from the same master signal. A hedging account's history shows discrete tickets, each with its own open time, close time, and P/L. A netting account's history shows a stream of deals against a rolling position, where the "P/L" of any individual deal only makes sense in the context of the running average price of the net position at that moment.

If you're trying to reconcile a follower's reported results against a master's reported results, expect the shape of the two reports to differ even on a good day when nothing structurally broke. This is a reconciliation and reporting problem on top of the exposure problem discussed above, and it's a separate reason to be careful about mixing account modes in a copier setup. It also compounds with other sync issues that already complicate multi-account setups, like the timing and slippage risk that shows up whenever a copier fans a signal out to more than one follower, so account-mode mismatch is one more variable to eliminate rather than debug blind when a follower's numbers don't match the master's.

Checking your account mode before you connect a copier

The practical fix here isn't a copier setting, it's a pre-flight check. Before connecting a copier between any two MT5 accounts:

• Confirm the account mode of both the master and the follower. This is visible in the platform (account properties) or programmatically via ACCOUNT_MARGIN_MODE. Don't assume; ask your broker directly if it isn't obvious, since this is configured per account and isn't something you can infer just from knowing which broker or platform version you're on.
• If both are hedging or both are netting, you're clear of the structural mismatch described here. Ordinary same-direction position building, in either mode, copies cleanly.
• If they differ, figure out whether the master ever intentionally holds opposing positions on the same symbol. If it never does, a mismatch is inconvenient for reporting but survivable for exposure purposes, per the add-to-position case above.
• If the master does run a genuine two-sided hedge as part of its strategy, do not bridge it to a netting-only follower. That specific exposure cannot be faithfully replicated there. This isn't a configuration problem to solve, it's a limit of what the netting data model can hold.

One wrinkle that can force this mismatch on you even if you'd rather avoid it: some brokers and jurisdictions mandate netting-only accounting. In the US, NFA Compliance Rule 2-43(b), the so-called FIFO rule that took effect in 2009, prohibits Forex Dealer Members from carrying offsetting long and short positions in the same customer account and requires those positions to be offset on a first-in, first-out basis, which effectively requires netting/FIFO-style accounting for accounts held at NFA-regulated US forex dealers. If your follower account happens to be a US-regulated retail forex account and your master runs a two-sided strategy on a hedging-enabled offshore or futures account, that mismatch isn't a choice you made, it's a regulatory floor under the follower account. Verify the current rule text and your broker's specific implementation directly, since NFA rules and broker interpretations get updated. The same caution applies more generally: always confirm your broker's current default account mode and whether it can be changed at all, since this varies by broker, by jurisdiction, and can change over time even for the same account.

Exchange-traded futures don't have one universal rule here either. Whether a given futures account defaults to netting or hedging accounting under MT5's exchange margin mode depends on the broker's server configuration, not a single CME-wide standard, so confirm this with your broker or prop firm rather than assume it from the instrument type alone.

What this means in practice

None of this is an argument against copying between MT5 accounts. The overwhelming majority of copy-trading setups, master and follower building and reducing positions in one direction at a time, work fine regardless of which mode either account runs, because netting's arithmetic and hedging's ticket list agree on total exposure in that case. The failure mode is narrow but real: a master that deliberately runs opposing positions on the same symbol at the same time, feeding a follower that structurally cannot hold two sides of the same symbol at once.

If that's your setup, the fix isn't a smarter copier, it's matching account modes before you connect anything, or accepting that the two-sided piece of the strategy simply won't be replicated on that follower. Everything else, the ordinary scaling in and out of positions that makes up most trading days, copies across the mode boundary without drama.
