Question regarding stored data
Hi, I have a question about how the backtest portion of the analyzer works. I have noticed that if I have Ninja Trader connected to a live feed for several days, and I run a backtest, I will get a certain set of results. If I then exit Ninja Trader and reopen it and connect to a live feed again and run the backtest over the same time period as before with the same parameters, I will get a very different set of results.
I am curious to find out if there is a logical explination to this difference in results, and if there is any way to correct the problem.Tags: None

Then you settings/data are/is different. Please try this:
- start NT
- connect to your data vendor
- Tools->Historical data->Reload: (re)load any period you wanted to backtest
- disconnect from your vendor
- open strategy analyzer and run a backtest
- save results (screenshot...)
- restart NT
- don't (!) connect
- open strategy analyzer and re-run backtest with exact (!) same settings
-> results will be the same

Alright. I will have to see if I can figure out a way to work around the problem. One thing that I forgot to mention though, is that my account performance tab is not even close to showing the correct trades for my account. It seems to just make up trades, quantities, and profit and losses. I have tried resetting the database, but that doesn't solve the problem. Would this and the different backtest results be related at all?
