    Exit Methods Instead of Set Methods for Stop Loss and Profit Target

    Do you have a good example of how to properly use Exit methods to set both a stop loss and profit target when entering a new position?

    In the OnOrderUpdate method I create both an ExitLongLimit and an ExitLongStopMarket (Let's just talk about long positions for the sake of simplicity.)

    Then I resubmit those with each OnBarUpdate to keep them alive during the life of the position.

    This is sort of working, but I keep running into various issues and I'd just like to make sure I'm following the recommended pattern.

    Hello Steve,

    Thanks for your post.

    The SampleOnOrderUpdate strategy demonstrates how this can be done. We typically advise using OnOrderUpdate to assign orders to Order objects, and then to submit Exit orders from OnExecutionUpdate. It is permissible to assign Order objects directly from Exit methods in OnExecutionUpdate.

    I highly recommend this framework for robust strategies. Please also see the documentation linked with the sample.

    Let us know if you have any questions and we will be happy to assist further.

      Thanks, Jim.

      So, using the sample code, I'm still running into an anomaly I saw previously.

      I've taken the exact strategy code from the example and just changed the size of the stop loss and profit target.

      My data series is ES ##-## daily bars from 1/1/2018 to 1/1/2019. Kinetick data.

      If I run the strategy code (included below) on my chart, it makes a few trades, then halts.

      Click image for larger version  Name:	2019-05-27_9-51-24.png Views:	1 Size:	20.6 KB ID:	1058895

      The last order is a market long entry on 2/14/2018. It is submitted, accepted, then working, but it never fills.

      Click image for larger version  Name:	2019-05-27_9-54-05.png Views:	1 Size:	41.2 KB ID:	1058896

      If I change the stop and target size to say, 120, instead of 100 ticks, then it just moves the date where the halt occurs to 4/4/2018 I believe.

      Can you help me understand what is happening here?

        Hello Steve,

        Thanks for providing a scenario for us to test.

        I have seen this behavior when combining Set and Exit methods, but I am looking into what is happening further in this case.

        I will follow up after I have been able to fully analyze.

          There appears to be a pattern when the trading halts. By changing the start date of my ES ##-## Day bars series, I can get the halt date to occur on different days.

          I'm using slightly different code than the code posted above, but the basics are the same. You can observe similar patterns with the posted code by changing the date range. I'm still using Exit methods, not Set methods.

          Not sure if these patterns are significant, but
          • The last active bar is always an up bar with a long lower shadow
          • The three bars (the last active bar, the one preceding it, and the one following it) are always trending up.

            Hello Steve,

            Thanks for your patience.

            This comes down to the backtest coming across an over fill scenario on both exits. Since the bar's data points are used to simulate the order fill without actual price action, a scenario where both the target and stop fill on the same bar can be encountered. This creates an overfill which then prevents the next entry order from reaching a Filled state from a Working state.

            To workaround this, you can use High Order Fill Resolution, or you can add a single tick data series to the script and submit orders to the single tick data series.

            High Order Fill Resolution - https://ninjatrader.com/support/help...FillResolution

            Please let me know if there is anything else I can do to assist.

              Thanks, Jim.

              OK. That makes sense. I can see now that the pattern where this occurs is on bars where both the stop and the target are triggered.

              I can also confirm that using Historical Order Fill Processing = High (HOFP=High) with some multiple of minute bars bypasses the problem.

              I'm good to go and can work around this in a number of ways, but are you submitting a ticket on this?

              Obviously, with HOFP=Standard, the backtest should not halt. The fill engine should be able to choose either the target or the stop and proceed.

              HOFP=Standard is a useful part of a strategy development methodology because of it's speed. It's a good first pass giving ball-park performance numbers which can later be refined using additional, more time consuming, methods.

              Thanks for your assistance,
              Steve

                Hello Steve,

                Thanks for the reply.

                A ticket was submitted previously on this behavior and our Development team is aware of this limitation with standard fill and orders filling on the same bar.

                We are tracking impact to consider improving this with the feature request ticket ID SFT-2778. I have added a vote on your behalf.

                We cannot guarantee any timeframe or promise fulfillment, but your impact and interest is tracked.

                Let me know if there is anything else I can do here.
