Margin ratio is the Equity over Margin Requirements
Margin is a deposit (as a collateral) made to open a position, selling or buying, and maintain the opened position.
Margin is not a fee or transaction cost: it is a part of account balance.
However, you need to be using your margin carefully as it may increase profit potential just as much as it may cause risk of loss.
Balance is the account balance calculated with all closed positions.
It does not include the floating loss or profit.
Equity is the floating balance including the current floating loss or profit.
Equity changes in response to the market price of the open positions.
Margin Call Level is to be 50%, Stop Out Level is to be 30%.
When the ratio of Margin to Equity comes below the Margin Call Level, there will be warning red sign on the Trading terminal. When the ratio of Margin to Equity comes below the Stop Out Level, there will be compulsory closures of open position, starting from the position with biggest losses, just like stop loss execution.
Trading hours are 24 hours a day and five days a week.
