Strategy not working

[percma]

Hi

I've been having some problem with a strategy I've been working on.

It was not possible to enable it yesterday so I've created a new one and it did work on drawing a signal on the chart.
Only noticed that it was turning off randomly at some point (would find again the strategy not-enabled)
I went then to try the performance on the Strategy analyser and noticed that it won't generate any run (not even a log). At the same time again on the chart I have the problem that the strategy won't turn on.
Same strategy was drawing signals on the chart before and now not even that.
Many thanks

Hello percma,

Thanks for opening the thread.

The strategy is hitting an error in OnStateChange() under State.Configure. We can see the OnStateChange() error noted in the Log tab of the Control Center and we can take debugging steps to see which part of OnStateChange() the error is coming from. Since this is a Strategy Builder built strategy, I have taken steps to find the origin of the error.

It looks like you have your Profit Target and Stop Loss set to use indicator values. While the Strategy Builder does not limit you from doing this, it is not allowed to do in NinjaScript because the indicator would need to be assigned in State.DataLoaded or later. (State.Configure comes before State.DataLoaded. More information on NinjaTrader's states can be found at the end of this post.) I have requested that the menu items to assign the profit target/stop loss to an indicator value get removed so this issue can be avoided.

Your goal can be accomplished by unlocking the strategy code and assigning your profit target/stop loss to the appropriate indicator values in OnBarUpdate(). An example on setting profit target and stop losses in OnBarUpdate() can be found in the Reference Samples section of the help guide. I'll include a link below.

Information on NinjaTrader's state system can be referenced in the help guide as well. This information is publicly available.

will try to look at it. hopefully not behind my reach...
will come back if I need some clarification.

thanks

ok. out of my reach.

in substance you are saying that I can't link any order management signal to any indicator available if I use the strategy builder?

Hello percma,

The limitation is that it is not possible to use an indicator for SetProfitTarget, SetStopLoss, or SetTrailStop in the Strategy Builder due to where the generated code is placed.

Another approach you may take can be to unlock the strategy when finished and then move the Set methods to the end of State.DataLoaded instead of where they are currently placed. This would not update automatically, but should allow you to place your stops and targets in reference to your indicator.

Please let us know if you have any issues with this approach.
