How to delete historical data.

[Czarek]

Hello.
1.How to delete historical data of one futuresfuture without deleting instrument. I have corrupted data of ES 03-12 and when I reload historical data, data haven't been changed so I would like to delete this data and download them again.

2.During the strategy working in the gird Unrealized shows strange numbers I would like to ask also what could be the reason of this?

Hello Czarek,

Thank you for your post.

1.) You can go to Tools --> Historical Data --> Delete to delete this data.

2.) Please try repairing your database: Tools --> Options --> Misc --> Repair DB. Then reconnect and see if the unrealized PnL shows properly.
