Consider a trader has a position worth 100 XBT at a price of 100 USD. The trader sets their margin method to Isolated Margin and posts 4 XBT worth of initial margin, and their liquidation price is set to 97 USD. Their Margin Balance is now 96 XBT.
Soon after, the price falls 6 USD to 94 USD. On the way down the liquidation engine assumed control of their position at their liquidation price of 97 USD.
The trader has only lost the 4 XBT that they assigned via Isolated Margin but has had their position liquidated. Additional funds were not used to avoid liquidation because Isolated Margin was set. If the trader had used Cross Margin, they would have had a larger unrealised loss (6 XBT), but they would have kept the position from being liquidated.
You can use the Leverage Slider as per below to adjust Leverage to a desired level. Adjusting this leverage will affect your Liquidation Price. If you slide it to the far left then you will move out of Isolated Margin and back into Cross Margin.
