Leverage — a way to open a trading position while only placing a small deposit. Margin trading lets you trade with more money than you actually have.
Minimum margin — works as collateral for your loan. If you make losing trades, you’ll have to pay your lenders out of your minimum margin.
Initial margin — the amount of money you put up for a leveraged trade — can be 10%, 30%, 90%, etc of the leveraged amount.
Liquidation value — the difference between your buying power and the amount of money you own.
Margin call — a request to either leave your leveraged position or add more money beyond your initial margin.
Maintenance Margin Requirement — how much of your own money you need to put up to open and stay in a leveraged position.
