Frequently Asked Questions

How is the estimated liquidation price calculated for perpetual futures?

For isolated linear USDT perpetual contracts, long liquidation price is estimated as Entry Price * (1 - 1/Leverage + MMR/100). Short liquidation price is Entry Price * (1 + 1/Leverage - MMR/100).

Can I calculate position quantity by specifying margin in USDT?

Yes. Switch the position sizing mode to Margin (USDT), and the calculator will automatically compute Quantity = (Margin * Leverage) / Entry Price.
