What are margin, margin level, and free margin?

Margin is the minimum amount of money you need to have in your trading account to open new or maintain existing positions on the market

Margin level is calculated using the formula (Equity/Margin) x 100%, where Equity reflects your trading account balance, plus or minus any profits or losses from open positions.

Free margin, meanwhile, refers to the funds you have available to open and maintain positions, and is calculated by subtracting Margin from your Equity.
