How to calculate liquidation margin and margin ratio?
To calculate your liquidation margin and margin ratio, you need to know your equity, your used margin, and your maintenance margin. The maintenance margin is the minimum percentage of used margin that you need to keep in your account to avoid liquidation. It is usually set by the exchange or broker and can vary depending on the market conditions and volatility. For example, if the maintenance margin is 0.5%, you need to have at least 0.5% of your used margin as equity to avoid liquidation.
The formula for liquidation margin is:
Liquidation margin = used margin x maintenance margin
The formula for margin ratio is:
Margin ratio = (equity / used margin) x 100%
For example, if you have $10,000 in your account and you open a $100,000 position with 10x leverage, your used margin is $10,000 and your equity is $10,000. If the maintenance margin is 0.5%, your liquidation margin is $50. Your margin ratio is 100%. If the price of the asset moves against you and your equity drops to $9,950, your margin ratio drops to 99.5%. If the price drops further and your equity reaches $50, your margin ratio reaches 0.5% and you get liquidated.
