How to switch between one-way and hedge mode for a contract? (Position Settings)

Understanding Position Mode Fundamentals

1. One-way mode allows a trader to hold only a single position direction—either long or short—at any given time for a specific contract.

2. Hedge mode permits simultaneous long and short positions on the same contract, enabling more complex risk management strategies.

3. The position mode is not a per-order setting but a global configuration applied to all contracts under the same trading account.

4. Switching between modes requires the account to have zero open positions and no pending orders on all contracts within that trading pair group.

5. Some exchanges enforce mandatory margin type alignment when changing modes—cross margin must be disabled before entering hedge mode on certain platforms.

Step-by-Step Mode Switching Procedure

1. Log into the trading interface and navigate to the “Contract Trading” section, then locate “Position Settings” or “Account Settings” in the top-right corner.

2. Verify that all active positions across BTCUSDT, ETHUSDT, and other related perpetual contracts are fully closed.

3. Cancel every open order—including stop-market, take-profit, and trailing stop orders—on all contracts tied to the selected symbol group.

4. Locate the toggle labeled “One-way / Hedge Mode” and click it; a confirmation dialog will appear warning about margin recalculations.

5. Confirm the action. The system will instantly update the mode and recalculate available margin, unrealized PnL display logic, and position aggregation behavior.

Margin and PnL Behavior Differences

1. In one-way mode, unrealized PnL is calculated as the net difference between entry price and mark price across the entire position size.

2. Hedge mode displays separate unrealized PnL values for long and short legs, with no automatic netting unless manually triggered via close-all functions.

3. Initial margin requirements increase in hedge mode because both sides are treated as independent exposures requiring full collateral coverage.

4. Liquidation price computation becomes asymmetric—each side has its own liquidation threshold based on its individual leverage and entry point.

5. Cross-margin settings behave differently: in one-way mode, cross-margin applies to the net position; in hedge mode, it applies separately per leg unless explicitly restricted by platform rules.

Common Errors During Mode Transition

1. Attempting to switch while holding a position results in an error message stating “Cannot change position mode with open positions.”

2. Leaving conditional orders active—even if they are far from current market price—blocks the transition until fully canceled.

3. Using API endpoints without first checking position status may return HTTP 400 with error code “POSITION_MODE_SWITCH_FORBIDDEN.”

4. Some platforms prevent switching during maintenance windows or when futures funding rate settlement is active.

5. Enabling hedge mode on accounts previously using isolated margin may trigger automatic margin type reassignment, affecting existing position leverage caps.

Frequently Asked Questions

Q1. Can I switch position mode while having open positions on different contracts?No. All contracts sharing the same underlying asset—such as BTCUSDT, BTCUSD, and BTCUSDT_SWAP—must have zero exposure before the switch is permitted.

Q2. Does changing to hedge mode affect my existing order history or trade records?No. Historical fills, executed orders, and audit logs remain unchanged. Only real-time position handling and margin allocation logic are modified.

Q3. Is there a cooldown period after switching modes before I can switch again?Most platforms impose no fixed cooldown, but repeated switching within minutes may trigger rate-limiting warnings or require email verification for security reasons.

Q4. Why does my available balance drop significantly after enabling hedge mode?This occurs because hedge mode calculates required margin independently for each directional position, eliminating netting benefits present in one-way mode—especially noticeable when holding large opposing positions.
