how to delete all the historical data for multiple symbols?

[comingme]

The "tools->historical data" menu allows this but I have to click mouse for each symbol. And I have hundreds of symbols.

Thanks for your help.

Hello comingme,

Thank you for your post.

Unfortunately deleting historical data for multiple instruments is not supported within NinjaTrader at this time.

I will forward this to our development team for future considerations.

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

Do you know in which file the data is saved?
If so, may I delete that file?
By the way, thanks very much for your quick reply.

Hello comingme,

The data is stored within the NinjaTrader database. If you would like you may reset the database to remove all information. With this procedure you will lose all historical data, executions and ATM Strategies.

If you would like to reset the database please go to the Control Center-->Tools-->Options-->Misc. tab-->Reset DB

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