You can see the price that I set which is $60000. You can see the estimated liquidation price which is $39605.2. Not $44000. ..
It is difficult for us to establish the truth in absentia, but according to the screenshot, you open a position not for $300, as required by the OP, but for $180. And accordingly, for this reason, the liquidation price will have a different meaning. I myself cannot demonstrate such a screenshot, since I have open positions on derivatives and the margin exceeds that of the OP.
