When in process of trading your Usable Margin takes the value below the minimum margin requirement, you receive a Margin Call.
It means that all trading operations are prohibited. If you try to trade, you will receive such a message.
All your actions are stopped. You have to increase your balance. Otherwise all your positions will be closed.
Note: The minimum margin requirement in UniTrader equals zero.
Note: After Margin Call has happened, Equity, Used Margin, Usable Margin and Summary P/L continue to be recalculated, so Usable Margin can become positive again, but this doesn’t cancel Margin Call.
Note: If you are trying to open position, which requires too much margin and can lead to Margin Call you will receive the following message.
