Forex Netting Explained: Netting vs Hedging on MT5

What forex netting means

Netting describes how an account records open trades in the same symbol. On a netting account, the platform holds one position per symbol, so a new trade in the opposite direction reduces that position instead of opening a second one. The result is a single net exposure per symbol, such as EURUSD.

The term has two common uses. In a trading platform, it describes position accounting. In treasury and settlement work, netting can also mean offsetting payment obligations between counterparties. This guide covers the trading-platform meaning, which is the one that shapes MT5 accounts.

Netting matters to a broker because it sets how client positions appear in the platform, how a close is recorded and how the back office reads the book. Decide the account mode with your technology, risk and operations leads before the first client account is opened.

Netting versus hedging on MT5

MetaQuotes describes two position systems in its MetaTrader 5 help on trading principles (Android). In netting, only one common position for a symbol can exist at a time. In hedging, you can hold several positions on one symbol, including opposite ones. The same page states that the broker decides which system applies to an account.

The diagram below shows the same two trades under each system, so the difference in position count and close steps is visible without reading the table first.

Position handling, margin and closing

The table compares the points operators ask about most often. The margin row describes the calculation rules, not a number. Margin depends on symbol settings, leverage and the broker’s configuration.

• Positions per symbol
  Netting account: One position per symbol at a time
  Hedging account: Several positions per symbol, including opposite ones
• Adding an opposite trade
  Netting account: Offsets or reduces the existing position
  Hedging account: Opens a separate position; existing positions stay open
• How a close works
  Netting account: An opposite trade on the same symbol and volume closes the position
  Hedging account: Each position is closed explicitly
• Margin rule (MQL5 mode)
  Netting account: RETAIL_NETTING: margin calculated based on the symbol type (SYMBOL_TRADE_CALC_MODE)
  Hedging account: RETAIL_HEDGING: same calculation, taking the hedged margin (SYMBOL_MARGIN_HEDGED) into account

MetaQuotes also states that a position cannot be reversed in the hedging system. A reversal on a hedging account is therefore a separate close and a new open, which should be tested as two steps.

Worked example: two trades on one symbol

Take a hypothetical client who trades EURUSD in two steps. The volumes are invented for explanation. They are not market data and not a performance result.

1. Buy 2.00 lots of EURUSD.
2. Sell 0.50 lots of EURUSD.

How MT5 identifies the account mode

MetaQuotes says the system used depends on the account and is set by the broker. Developers can read the margin mode from the terminal. In MQL5, the ACCOUNT_MARGIN_MODE property, read with AccountInfoInteger(), returns one of three values.

• ACCOUNT_MARGIN_MODE_RETAIL_NETTING: used for the OTC markets to interpret positions in the netting mode (only one position can exist for one symbol). Margin is calculated based on the symbol type (SYMBOL_TRADE_CALC_MODE).
• ACCOUNT_MARGIN_MODE_RETAIL_HEDGING: used for the exchange markets where individual positions are possible (multiple positions can exist for one symbol). Margin uses the same calculation and takes the hedged margin (SYMBOL_MARGIN_HEDGED) into account.
• ACCOUNT_MARGIN_MODE_EXCHANGE: used for the exchange markets. Margin is calculated from the discounts in the symbol settings, which the broker sets but which cannot be lower than the exchange values.

Who sets the mode

The broker sets the mode, so confirm it for each account group in writing. Do not assume that a demo environment reflects the live configuration. Check the value your code will receive on the account type you will actually run.

What netting changes for brokers and prop operators

For a brokerage, netting affects the client view, the reporting layer and the way the back office reconciles open positions. For a prop evaluation business, it can also affect how challenge rules count exposure. Map each client-facing screen and report to the position model before launch.

• Record the account mode for each account group in the account set-up file.
• Test partial closes, full closes and reports with the volumes you expect to see in production.
• Check that risk and exposure reports read the net position from the platform, not from a separate ledger.
• Document how copy-trading, IB and reporting tools read positions and volumes under each mode.

FxTrusts’ white-label brokerage technology describes the scope we propose: the broker keeps its entity, client terms and marketing, and providers supply named technology layers. Platform access depends on the licence or access holder named in the contract. Hosted access is covered on the hosted platform access page.

Position design sits beside execution design. If orders go to external liquidity, the account mode governs how the platform records the resulting position. Review it alongside the liquidity scope and the execution broker model.

Questions to ask before you choose a mode

Put these questions to your platform provider and broker in writing. The answers belong in the signed scope, not in a call note.

1. Which account mode applies to each account group, and can it differ by account type?
2. How does the platform report a partial close, a full close and an opposite-direction order to the CRM and the back office?
3. Which MT5 features, Expert Advisors and copy tools are supported under that mode?
4. What is the change process if the mode must be altered after accounts exist?
5. Which licence or access holder is named for the MT5 environment?

The MT5 white-label solutions guide sets out the wider decisions that sit around this one.

Risk and client communication

Netting and hedging change how positions are shown and closed. They do not change how much a leveraged trade can gain or lose. Leveraged FX and CFD trading carries a high risk of losing money quickly. The European regulator ESMA reported in 2018 that 74-89% of retail accounts typically lose money on CFD trading, and in the EU it introduced leverage limits and a standard risk warning.
