Why did I receive a margin call when my trading account is not in a Margin Call state?
Sometimes it may happen that the trading account might reach a margin call event when there are open positions and the equity is found short during extremely volatile market conditions, however, the account may have quickly recovered if the market has bounced back within a very short span of time.
It is extremely important to constantly monitor your trading account's margin level should there exist an open position and take an action to protect your trading account from entering a margin stop out.
