      Dear All,

      I'm using stoploss with the parent-child mechanism. It seems that the stoploss order I define is NOT working properly on the first day of the trade and I would like to understand why. I have built a toy strategy to illustrate behaviour. The system is built for GBPUSD on daily bars and we use cheat-on-close. The scenario is as follows:

      1. on Thursday 23-Jun-2016, we enter a long position (market order) with an attached stop-loss (stop order)
      2. entry order filled (submitted, accepted and completed) on the close of 23-Jun-2016 (cheat-on-close): 1.48380
      3. stoploss order to sent (submitted/accepted) at price 1.453830065123425
      4. stoploss is hit on Friday 24-Jun-2016 (see status completed) but order is filled with the open price of next business day (Monday 27-Jun-2016) instead of the stop price (1.34130 instead of 1.453830065123425)
        5 Finally, if I do the same thing but enter the position one day earlier (Wednesday 22-Jun-2016), the stop loss is indeed hit properly on Friday 24-Jun-2016 at the stop price

      Any help on this would be greatly appreciated!

      Regards
      Lamp'

      Market data looks like (O/H/L/C):

        try to set coc=False for stop order:

        self.stoploss_order[asset] = self.sell(exectype=bt.Order.Stop, data=asset.data,
                                                           price=stop_price,

                                                           coc=False)

        it looks like your stop order is also affected by broker's cheat-on-close mode.

          Hi @ab_trader ,
          Great insight but unfortunately it does not solve the issue. I have also tried to set coc to false at broker level. Traces can be found below (same result in term of exit price but obviously entry price is different; in both case, the stop price is "ignored"). It is quite strange.

          If you have any other ideas to investigate, I'm all ears :)

          Regards

          set coc=False for stop order

            Honestly no ideas for now, but I think this issue is specific to your code. First, this issue is independent from the cheat-on-close. Second, it depends on the bar: one bar returns the exit with the issue, another bar - doesn't.

            I'll try to recreate the problem using some arbitrary entries and stop orders to exit.

              hello @ab_trader
              quick update. I did not resolve the issue per se but I have found the root cause. Issue lies with the parent/child mechanism.

              if I submit the 2 orders (main order and stoploss order) separately as follows:

              main_order = self.buy(exectype=bt.Order.Market,
                                    data=data0,
                                    size=size,
                                    name='ENTRY LONG',
                                    transmit=False)
stoploss_order = self.sell(exectype=bt.Order.Stop,
                                     data=data0,
                                     price=stop_price,
                                     size=size,
                                     name='STOPLOSS for LONG',
                                     parent=main_order)

              Then the stoploss is actually hit at stop price (1.453830065123425)
              See output:

                Were you able to figure out the solution?

                I finally got some time and was able to recreate the issue on a simple script.

                  For now, I'm just submitting 2 separate orders (one for LONG/SHORT and this other for stoploss). this achieves the results I want. regards
