Negative bars from IB paper account

[Aduciicba]

Hello. I'm quite newby with NT. Following the instruction on your web site I've succesfully set the connection between NT 8.0.23.2 64-bit and TWS 978.2c. I've been trying to test custom strategy on my paper account.
I noticed very strange bars data on the instrument chart. Several historical bars were far below zero and every further bar got there after being closed. But current processing bar and current price seemed to be normal. There are historical data on the second screenshot, which appeared after strategy start. I tried to remove them and start again, but it didn't help. Could you please explain what has happened and what should I do to get normal bar values. Thank you

Hello Aduciicba,


Thank you for your post.


Please clarify; are you asking a question about your custom strategy that you are trying to test or about the historical data that is showing on your chart? You posted in the Strategy Development section of our forums, so if you are not asking about your strategy I would like to be sure we move the post to the correct forum section and address your concerns appropriately.


I look forward to your reply.

My apologies, it's probably the wrong section. My problem is with historical and live data from IB provider, not with the strategy.
