Installation and Historical Data

Is there a way to remove all of the old accounts and executions from previous years?

I use this technique, but there may be a newer way.

If you goto the db folder & remove your database file,
NT will create a new pristine empty database the
next time it starts up.

Of course, backup your old database file, just in case.

And make sure to EXIT NinjaTrader before doing this.

This will (obviously) clear out accounts and history, but
your connections are fine, your ATMs are fine, but you
may have to go to Tools > Instrument Lists to update
your instruments.

NT Support can advise further.

Hello k3wicx,

Thanks for your post.

The technique that bltdavid could be used to accomplish this.

You should create a backup of your database by going to Tools > Export > Backup file.

Creating a backup archive: https://ninjatrader.com/support/help...up_archive.htm

Then, exit NinjaTrader, go to the Documents\NinjaTrader 8\db folder, rename the NinjaTrader.sqlite file, and restart NinjaTrader.

Once NinjaTrader restarts, a new database file will be created.
