Fund management and trade management are related to leverage in our trading account leverage which if too large will be a great opportunity to open positions at the same time but also a huge opportunity to not be restricted in trading even if we run out of capital without relating to existing margin trading , therefore to prevent losing control in many positions in trading with openness we have to place limits on trading accounts by making us a little leverage and leverage to limit our desire to open positions very much in the near future and this is a one time preformance The main reason drai margin call because
lack of attention to margin management.
