Margin Rules for Hedged Positions: Why Offsetting Trades Still Use Margin

Many traders assume that holding opposite positions reduces margin. The rule depends on the broker and jurisdiction.

Some brokers allow hedging, meaning a long and a short in the same pair at the same time. Of these, some charge no margin on the hedged portion, or charge a reduced margin, while others charge the full margin on both sides. A few broker regimes, particularly in the United States, prohibit hedging in the same account, and require positions to net automatically, closing the existing position when an opposite one opens.

The details matter for margin level calculations. If a broker charges margin on both legs, a locked position still ties up capital. If the broker offers hedge margin, the required amount drops, but conditions apply, such as requiring equal volumes.

Costs persist regardless. A locked position pays spread on both entries and swap on both legs, and leaves you with the same decision of when to close, as discussed earlier.

Netting versus hedging accounts also differ in how stops and take profits are handled, and in how partial closes work. In a netting account, adding to a position changes the average price, and a single stop applies to the total.

Check your account type and read the margin policy. Test with a small position to see how the platform reports used margin before relying on the assumption.

Practical step: open a micro position and its hedge on demo, and observe how used margin changes.

Testing on demo with a micro lot is the quickest way to know. Margin rules for hedges vary so much between brokers that assumptions are usually wrong. Open 0.01 long, note the used margin, then open 0.01 short on the same pair and see what happens to the number. If it stays the same, you're on hedge margin. If it doubles, they charge both legs. If the long disappears, it's a netting account. Do it once on a weekday and once close to the weekend, because some brokers raise hedge margin before Friday's close. Five minutes of testing saves you finding out during a margin call when the account is already tight.

Netting accounts catch people coming from hedging accounts. Opening a sell when you're long doesn't create a hedge, it just reduces or closes your long. The surprise usually comes with stops and targets too. On a netting account, a pending sell order meant as a separate trade can partly close your existing position when it fills, and the remaining position may keep the old stop or lose it depending on the platform. MT5 shows whether the account is hedging or netting in the account details, so check that before you place anything. If you rely on separate positions for scaling in and out, a netting account changes how you have to manage the whole trade.
