A question about calculate balance

[ruifeng96150]

In my opinion, balance mean to cash. So when open a new order, the balance should minus cash used in orders. But in _create_hedged_order function, not update balance. It's a bug or I have misunderstand？

You are referring to equity. According to Metatrader, equity is calculated as balance+profit.
