This is very useful code.  When I import to.fxdreema, it says ' no record found'

Would you upload.it again.  Thanks.

In this optimized version, we maintain a list of orders for the current symbol and update it whenever a new order is opened or closed. We also directly calculate drawdown using the maximum balance and current balance. These changes should improve the efficiency and performance of the expert advisor.
