How do I access the Trade object from within the next() method of Strategy?

[Kristofer Monisit]

I would like to keep track of the time I am currently in the trade. I know that the trade object has a barlen attribute. I would like to check for it in the next() method of the Strategy. How do I do it?

I was doing the following:

    def notify_trade(self, trade):

        if trade.justopened:
            self.trade_length = 0

        if trade.isclosed:
            self.trade_length = None


    def next(self):

            pos = self.getposition()

            if pos:
                self.trade_length += 1
