One-Way versus Hedge Mode: Understanding Futures Position Modes
When opening a futures account, you may be asked to choose one-way or hedge mode. This setting completely changes what happens when you place a short order while holding a long. The same button may close a position in one account and open an opposite position in another.
What position mode determines
Position mode determines whether you can hold a long and a short in the same instrument simultaneously. Names vary between exchanges, but there are two basic structures.
One position per instrument.
Its direction is either long or short.
An opposite order reduces or closes the existing position.
Hedge mode: Both directions
Long and short positions exist separately in the same instrument.
An opposite order opens a new position on the other side.
Every order must identify the intended leg.
Most exchanges default to one-way mode. Hedge mode must be enabled separately in account settings.
One-way mode: An opposite order closes exposure
An opposite-direction order first offsets the existing quantity. If its quantity exceeds the holding, the remainder creates a position in the opposite direction.
Current position: Long 0.5 BTC.
[Short order for 0.2]
0.2 is offset → Long 0.3 BTC remains.
P&L is realized only on the 0.2 closed.
[Short order for 0.5]
0.5 is offset → No position remains; the entire position closes.
[Short order for 0.8]
After offsetting 0.5, the remaining 0.3 becomes a new short of 0.3.
The direction reverses completely.
The third case is a common beginner mistake: entering a generous quantity to close a position ends up reversing it. The Reduce Only option prevents this. With it enabled, the order can only reduce the position; the portion exceeding the holding is automatically ignored. Enabling it routinely for closing orders is safer.
Hedge mode: Long and short exist independently
Hedge mode allows a long of 0.5 and a short of 0.5 at the same time. Net exposure is zero, but two separate positions remain in the account. Each leg has its own entry price, unrealized P&L, stop-loss and take-profit orders.
The key point is that only price P&L offsets. Costs do not cancel; both sides incur them.
BTC at 60,000; long 0.5 + short 0.5.
Each leg's notional value = $30,000.
Margin at 10x leverage
Long $3,000 + short $3,000 = $6,000 locked.
In one-way mode, a net position of zero would lock zero margin.
Entry and exit fees, assuming a 0.05% taker fee
Entry: 30,000 × 0.05% × 2 = $30.
Exit: 30,000 × 0.05% × 2 = $30.
Total: $60.
Funding fees
For the same instrument on the same exchange, one side pays and the other receives,
so they generally offset. This does not apply across different exchanges.
Holding both legs is therefore not simply freezing P&L; it continues to consume fees and margin. A fee calculation may show that you paid $60 round trip to achieve “nothing happened.” Funding generally offsets within the same exchange, although differences in entry timing can prevent a perfect match when rates vary substantially.
Liquidation happens separately for each leg
This is one of the most misunderstood aspects of hedge mode. Zero net exposure does not mean there can be no liquidation. With isolated margin, each leg relies on its own margin, so one leg can be liquidated first.
Long 0.5 @ 60,000.
Liquidation price ≈ 60,000 × (1 − 0.10 + 0.005) = 54,300.
Short 0.5 @ 60,000.
Liquidation price ≈ 60,000 × (1 + 0.10 − 0.005) = 65,700.
If price falls to 54,000
The long leg is liquidated, consuming its $3,000 margin.
The remaining short of 0.5 creates a net short position.
A hedged account becomes a directional bet.
If price then rebounds, the liquidated long does not return, while losses on the short grow. Cross margin uses the entire account balance as a buffer, making this kind of isolated leg liquidation less likely, but allowing losses to spread across the account. In either case, the maintenance margin rate and leverage determine the distance to liquidation.
Which mode should you use?
One-way mode is sufficient for most individual accounts.
• You trade only one direction at a time.
• You want to avoid accidentally opening an opposite position.
• You prefer seeing a single position on the screen.
When hedge mode is useful
• You run several automated strategies with different approaches in one account.
• You use futures to hedge spot holdings.
• You manage long-term and short-term legs separately.
A common misconception is that opening the opposite side in hedge mode “stops the loss” on a trapped position. Locking in the price P&L this way is equivalent to fixing the loss at that point while continuing to pay fees and tie up margin. It produces nearly the same result as closing, with extra costs. It also adds another decision: which side to release, and when. If the position itself is too large to tolerate, the response is smaller position sizing, not another leg.
What prevents a mode change?
Position mode cannot be changed at any moment. Nearly all exchanges require these conditions:
1. No open positions in the instrument or account.
2. No outstanding unfilled orders.
→ Otherwise, the exchange rejects the change.
→ Scheduled stop-loss and take-profit orders count as unfilled orders.
This explains failed mode changes while a stop order remains active. All pending orders, including conditional orders, must be canceled first.
API and automated trading add another requirement. In hedge mode, every order must specify its leg, long or short. Sending one-way order code to a hedge-mode account without this field can produce rejections such as “the specified position does not exist.” The position may be visible on the screen while every closing order fails. Conversely, hedge-mode orders sent to a one-way account may fail because the direction field is invalid. Even the correct order type is rejected if it does not match the mode.
How to check your setting
If you do not know your account's current mode, follow this sequence:
2. Open a small long, then submit a short for the same quantity.
• If the position disappears → One-way mode.
• If two positions appear → Hedge mode.
3. Close the test positions immediately after checking.
Use the minimum quantity for this test,
so the round-trip fees remain minimal.
Once checked, an account setting usually remains useful for a long time. Without checking, pressing a close button under pressure can leave you discovering later that exposure expanded instead. If ADL also reduces positions during severe losses, it may take considerable effort to work out how each leg was closed.
Three key points
① In one-way mode, an opposite order reduces or closes the existing position. A quantity greater than the holding reverses direction, so enable Reduce Only on closing orders.
② Hedge mode allows separate long and short holdings, but locks margin on both sides and charges fees on both. With isolated margin, one leg can liquidate first and suddenly create net exposure.
③ A mode change requires zero positions and zero unfilled orders. One-way mode is sufficient for most individual accounts.
Caution
The prices, quantities, margin amounts, liquidation prices and fee rates here are hypothetical examples illustrating the calculation structure, not measured values for a particular exchange or instrument. Liquidation formulas differ in how exchanges incorporate maintenance margin, fees and funding, so check the liquidation price displayed by your exchange. Mode names and switching requirements also vary. Leveraged trading can lose the entire principal. Your investment decisions and their consequences are your responsibility.
