About margin
What is margin?
Margin is the collateral required to open a leveraged position. It is not a cost, but a deposit held by your broker.
Margin formula
Required Margin = (Lots × Contract Size × Price) / Leverage
Free margin
Free margin = Equity − Used Margin. When free margin approaches zero, a margin call occurs.
