Margin: Margin is the money you need to make trades. It acts as a safety deposit or collateral. By using margin, you can control larger trades with a smaller amount of money.
Margin Level: Margin level is the ratio of your account's equity (current value) to the used margin (margin tied up in open positions), expressed as a percentage. It shows how much equity you have in your account compared to the margin being used.
Margin Level= (Equity/Used Margin)*100%
Free Margin: Free margin is the money available in your trading account that is not being used as a margin for open positions. It is calculated by deducting the used margin from your account's equity. Free margin can be used to open new trades or absorb potential losses. It's important to manage your free margin properly to avoid Stop-Out (liquidation).
