Problems enabling strategy

[angelvincent37]

Hello,

I created a strategy, I was able to load it and test it in playback mode. Later I wanted to change some parameters, I removed and put the strategy back but it is no longer enabled. It stays with the written in the chart (D) Name strategy and in the output I don’t see the written enabling strategy. What could be the problem?

Thank you

Hello angelvincent37

When adding a Strategy onto a chart, don't forget to check the checkbox "Enabled" to activate the Strategy.

Hello KonstantinosNT
I created various strategies and I know that I must check the "Enabled" checkbox, thank you but this isn't the problem

I think I found the problem: I use
AddVolumetric("ES 03-23", BarsPeriodType.Tick, 1, VolumetricDeltaType.BidAsk, 1, true);
commenting on this I have no problems, if I comment all the strategy except this line I have problems. How can I solve this problem? I noticed that using 1-tick volumetric bars is very heavy for strategy, ninja platform and CPU.

Hi angelvincent, Please first check the Log tab of the Control Center for any errors. There is likely a null reference exception due to this AddVolumetric call. I have an example here on how to use AddVolumetric in your script:

Hi CrisL,
In the Log Tab there is no error... I used the add volumetric in many strategies and I've never had this kind of problem. Inside the code, in the OnBar I use this control to avoid problems:

if (Bars == null) {
return;
}

NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe volumetricBarsType = Bars.BarsSeries.BarsType as NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe;

if (volumetricBarsType == null)
{
Print("volumetric bars == null");
return;
}

Should I use other control?

Hi, Please see post number 5 on the link I provided in my last post. It has an example of how to set up AddVolumetric for data access in OnBarUpdate.

Kind regards,

Hi Chris L,
I've seen the post you are talking about and I followed exactly the procedure described but the problem persists.

Hi, There is an example for download here for a reference sample:

https://ninjatraderecosystem.com/user-app-share-download/volumetricdata/

Please test out this one and if it does print data and function correctly, compare this code to your script and that should solve the issue.

Kind regards,

Hi Chris,

The Volumetric Data that you provided works well and for what I can see I use the same functions. the only difference is that what you provide is an indicator and i'm using a strategy so in the State.Configure I use the method AddVOlumetric() with the right parameters. Unfortunately I still have problems. For what I can see I have big isses when I try to load little bars as volumetric 1 tick bars ( playback stops immidiately after the begin ) instead when I load, for example, volumetric bars 150 tick playback goes with no problem. What I can do? Is a my pc problem, a platform problem? the porpouse of my strategy is to analize ask and bid volume in 1 tick bars and to control if theese bars are created in less than 0,5 second. I don't know if this could be usefull for you.

Thank you very much

Hi, I just tried this by loading a 1 tick series on the chart with no historical bars and it seems that it get exponentially worse as you go down in ticks. e.g. a 1000-tick volumetric chart loads fast, 100 is slower, 10 is worse, and so on. I will need some time to ask our development team about this performance issue.

Hi Chris,
I imagined that there was some such problem, I just didn’t understand if it could be due to the performance of my pc or platform. I hope that these problems can be resolved. I hope you can keep me updated if there are any changes, because at the current state of things I have to abandon this kind of strategy. Thank you very much for your support
