On the MoonBot futures terminal interface, after I bought a coin, I see an extra red line on the chart, what does it mean?

On the MoonBot futures interface, after you buy a coin, an additional red line appears on the chart, which is the liquidation line and when the price crosses this line, the exchange liquidates your position. On a long position, the liquidation line appears in the green stack, and on a short position, the liquidation line appears in the red stack.
