Market Replay is not hitting the OnBarUpdate method

[WaleeTheRobot]

Versions
8.1.3.1
8.1.4.0

Everything seemed fine with 8.1.3.1. I updated to 8.1.4.0 and it seemed to initially work, but I noticed the Market Replay stopped hitting the OnBarUpdate. I uninstalled and reinstalled the previous version. Now, I'm not seeing the Market Replay hit the OnBarUpdate at all. I removed all third party add-ons and it works in live.

Hello WaleeTheRobot,

Which playback mode are you using? Also have you tried to delete the data and re download it?

Hello WaleeTheRobot,

Which playback mode are you using? Also have you tried to delete the data and re download it?

I'm using the Market Replay data where you click to play replay the day and not the Historical. I downloaded this week's NQ 03-25 data this morning and still had the same issue. This is the print from the attached strategy. It no longer prints after the data starts to replay.

Hello WaleeTheRobot,

Are you playing through session hours? I tried the script and see the following prints:

I'm not sure why it wasn't working for me. I ended uninstalling NT, removing all the folders and reinstalling it. It seems to work fine now. Thanks.

I think I found the issue. I had a copy of System.Text.Json in the Custom directory. I didn't see any issues with it until I did a clean uninstall and removed the NT files. With the new clean installation, I copied it over from the .nuget directory and noticed NT complaining about not being able to load it when starting up NT. I removed it from NT Custom directory and reference it in .nuget directory and the loading issue went away and the OnBarUpdate issue went away. It seems that something was silently failing somewhere.

Edit:
I saw that there was one in C:\Program Files\NinjaTrader 8\bin\System.Text.Json.dll and thats the only one I got to work. I kept getting could not load assembly compile error if I copy it into Custom or if I reference .nuget then I get runtime errors for System.Text.Json.

[WaleeTheRobot]

This is kind of frustrating since I thought it was the referencing of the dlls. However, that was intermittent and it stopped hitting OnBarUpdate again. This is how I got it to consistently hit the OnBarUpdate when I click the play button for replay. Right click the chart and add the strategy. Check Enabled and click play. It'll now play like normal and enter the OnBarUpdate method. If I don't select Enabled on initial load of the strategy and click the Enabled in the Strategies tab with Accounts, Orders, etc then it won't enter the OnBarUpdate anymore. I attached the screenshots and an updated strategy. It just has a simple method to test the System.Text.Json. This is on version 8.1.4.0. I did notice the same behavior previously when I uninstalled 8.1.4.0 without removing all the files from NT and going back to 8.1.3.0. I didn't have this issue before upgrading to 8.1.4.0 the first time.

Hello WaleeTheRobot,

While I cannot assist with external nuget packages you can do this type of test without using that reference at all. If you are adding references that are newer versions of something NinjaTrader already uses that may cause issues, you can instead reference the version installed with NinjaTrader.

Regarding enabling the strategy, are you applying a new instance of the strategy and then checking the enabled box on that new instance after connecting to playback? If you are using an instance that previously was applied outside of playback that wont work, you need a new instance applied after connecting to playback so it selects the playback account.

[WaleeTheRobot]

Thanks. I think the issue probably is because I'm referencing something other than the one NT is using. I noticed NT having issues between compile or runtime referencing dlls if I copied them over to the Custom directory or reference it in a different directory. Referencing the below for the NinjaScript Editor worked.

C:\Program Files\NinjaTrader 8\bin\System.Text.Json.dll
C:\Program Files\NinjaTrader 8\bin\System.Memory.dll
