DueDEX offers leverage to most of its contracts. To keep a position open, trader needs to keep the minimum amount of value of the position on the exchange platform, known as the Maintenance Margin.
In general, Liquidation occurs when the position margin level falls below its maintenance margin level; when it happens, all the Initial Margin of a position will be lost.
You can always check the liquidation price of your position under the Open Position Tab. You can also change your liquidation price by adding extra margin and/or adjusting Leverage Sliders.
