notify_trade is not correctly recognize trade close when a trade is closed by stop loss or stop trail

[sanmao]

guys, I have two trades in my back test, the first is long, and the second is short. Both closed by stop trail and get profits. Buy notify_trade just recognize the two as one trade and loss money.
I don't know how to fix it.

    def notify_trade(self, trade):
        if not trade.isclosed:
            return
        
        self.log('OPERATION PROFIT, GROSS %.2f, NET %.2f' %
                 (trade.pnl, trade.pnlcomm))

Here is log
