Delete historical data and tickers

[siroki]

Is there a way to delete all historical data and mass-delete tickers? I have imported all NYSE tickers at some point but would like to delete them. And I would also like to clear all historical data and reload it.

Hello Siroki,

Thank you for your post.

To delete the historical data you can go to the following directory on your PC and delete the files you wish: (My) Documents\NinjaTrader 7\db --> Day, Minute and Tick folders contain historical data.
For the tickers in the instrument database, you will either need to manually remove them by going to Tools --> Instrument Manager, or resetting your instruments by going to Tools --> Options --> Data --> Reset Instruments.

Please let me know if I may be of further assistance.
