Question 1

What is margin ratio?

Accepted Answer

Margin ratio is your required maintenance margin divided by your account equity, as a percentage. It rises as losses eat your equity or as you add size. At 100% the exchange liquidates you. Keeping the ratio low means you have plenty of buffer between the current price and forced liquidation.

Question 2

What margin ratio is safe?

Accepted Answer

There is no universal number, but under 50% is generally comfortable and gives room for volatility. Above 80% you are dangerously close — a single sharp move can trigger liquidation at the worst possible price. If your ratio is climbing, reduce position size or top up margin before the market decides for you.
