      I'm trying to make my bot "long only" and I'm having issues with the execution.

          def __init__(self):
        self.dataclose = self.datas[0].close
        self.ind = AmaBands(plot=True, subplot=False)
        self.order = None

    def next(self):
        self.log('%0.2f' % (self.dataclose[0]))

        mean = self.ind[0]  # Current mean(moving average) value

        size1 = cerebro.broker.get_cash() * 0.035 / self.data
        size2 = size1 * 2
        size3 = size2 * 2
        size4 = size3 * 2

        pos = self.position.size

        stop = self.ind.bot[0]
        close = self.dataclose[0]  # Current close

        buy1 = self.ind.bot[0]
        buy2 = self.ind.bot2[0]
        buy3 = self.ind.bot3[0]
        buy4 = self.ind.bot4[0]

        sell1 = self.ind.top[0]
        sell2 = self.ind.top2[0]
        sell3 = self.ind.top3[0]
        sell4 = self.ind.top4[0]

        """Trade logic"""
        if not self.position:
            if close < mean:
                self.buy_order = self.buy(price=buy1, size=size1, exectype=bt.Order.Limit)
                self.log('Going long step.. %.2f' % close)
            elif pos > 0 and close > mean:
                self.sell_order = self.close(price=sell1, size=-size1, exectype=bt.Order.Limit)
                self.log('Exiting long.. %.2f' % close)

      So what I want is when price goes below my "mean" I want it to create one buy limit at my buy1 and only if price crosses above my mean and is in a position (ideally id put elif pos == size1 but this does not seem to work) I'll create a close position order.
      It seems I'm creating more buy orders than intended:

      I've looked trough the forums for hours please help :D.
      Once I figure out this part I can finish the logic.
      And it won't exit properly, what am I doing wrong?

      Regards,
      cept0r

        @cept0r said in Order execution confusion?:

        mean = self.ind[0]

        best way to understand what is going on while script running is to put more logging. what is the point of having only close values printed? how this can help? print your close, and mean, and all other data necessary to check the logic in the next(), in the notify_order(), etc.

        i think the issue is in the mean since you define set of values to it. but with what is shown it is the guess only.

          Changed the code abit and added a log for the mean I think there is a serious issue with my logging function.

          I want it only to be long and massage the entries and exits of that long until it fully closes or stops out which will start a new cycle of laddering long buys. Looks like it opens several positions at the same time.

            The script does what you programmed:

            • each bar your close < mean it issues limit order
            • after the first condition close < mean met, it starts to issue one more buying limit order each time close < mean since self.trades_occured = True now for all further bars
            • it look s like these orders are hanging in the system waiting for execution, hard to say, no prices and indicator ranges are shown, probably price never get lower than limit buy price
            • at certain point your close > mean and script starts to issue sell limit order
            • it does it each bar when close > mean since pos < size2 returns True always - no long position is open or short position (negative pos is open)
            • at certain point price goes high enough and these accumulated sell order are executed
            • hard to say if they are executed on the same abr or number of bars, since the date only is printed, but these intraday data

            I would advice you to look on the prices and indicators on the price history, find short time period where your entry/exit signals happen, and orders are executed, and debug your code. If it is hard to find that time period, then split the task: find the short time period where prices and indicators generate your entries and debug them, then do the same for exits.

              Ahaa I think I got it now, I just needs to make sure each step only issues one limit order and go from there. Thank you.

                Still stuck on this issue for a week now, anyway I could contact you on Discord/Telegram? In my head coming from a trading background this is so simple but I can't manually do the strategy fast enough for it to be viable..
