After you add margin, the liquidation price moves farther away from the current price. This makes your position's safety cushion thicker. The more margin you add, the safer the liquidation price becomes, but the way it works differs by margin mode. This article explains how the OKX contract liquidation price changes after adding margin, plus how to do it in isolated and cross margin modes.

Core logic behind liquidation price
The core trigger for liquidation is when the maintenance margin rate is ≤100%. The higher the maintenance margin rate, the safer the position. Adding margin directly increases the margin balance, raises the maintenance margin rate, and pushes the liquidation price farther away.
Differences between isolated and cross margin
Isolated margin mode
- How to add: After opening a position, click the + sign next to the margin balance in the position details and add margin manually.
- Range: You can add 10% to 100% of the trading account funds.
- Effect: As margin increases, the liquidation price moves away from the current price. More margin means lower liquidation risk for the position.
Cross margin mode
- Single-currency cross: There is no add button under the position. The full value of that currency is already used as margin. To add margin, transfer that currency into your trading account. It is automatically added to the cross margin and improves the margin rate.
- Multi-currency cross: There is also no add button. Transfer any supported currency into your trading account and it will automatically increase the position margin and improve the margin rate.
High risk warning: In cross margin mode, all positions share the same margin pool. Added margin can be used by all positions. If the market moves against you, losses are deducted from the entire account, not limited to one position as in isolated mode. Confirm your total risk exposure before adding margin.

How to confirm adding margin was successful
After adding margin, check the following three items on the position page. If all three match, the margin add succeeded:
- Margin balance increased by the same amount you added.
- Maintenance margin rate improved and is clearly higher than before.
- Estimated liquidation price moved away from the current price. For long positions it moves down; for short positions it moves up.
If these three values have not changed, the funds may not have been transferred to the trading account yet, or the operation may not be complete. Go to Assets → Transfer to check the status.
