Order Flow Cumulative Delta shows no data

I just ran into the issue again and deleting the cache folder again fixed the problem.

I've been seeing a pattern lately:

• Start NT and run my strategies. Everything works OK. Strategies run for a while (e.g. 20 hours).
• Disable the strategies, possibly make some small code changes and recompile. Re-enable strategies. Order flow is now corrupted on one or more charts.
• Stop NT, delete the db/cache folder, everything works OK again.

So, I can conclude that (1) the issue is definitely corruption in the data cache, and (2) it happens very quickly, within the span of one day. I should mention that at the moment I am only looking at one market (MES) with a few tick charts of various resolution.

Hello aworldnervelink,

Thank you for your reply.

When you re-enable the strategies after making code changes, are you completely removing them from the chart and re-adding them? This would be recommended if you are not.

What version of NinjaTrader are you currently using? We've released a new version since this thread was started, 8.0.23.2. Does this persist after updating to the latest version?

Thanks in advance; I look forward to assisting you further.

I have some disturbing news. Deleting the db/cache folder was previously working for me for months, but now it has stopped working. Even after deleting that folder and restarting I am still seeing nothing on the Order Flow indicator. So, that may have been a cargo cult solution.

I'm currently running 8.0.23.1, I will upgrade after today's session.
