Bid-Ask Volume Chart Grid

Hello,
There is a very annoying bug in the “Bar Time” data, on Range Charts, the actual “Bar Time” gets lost when a new bar is created. I mean to say this. As the current bar time is counted and the range bar chart creates a new bar, What is now the previous bar will have an incorrect bar time.
Thanks

Can anyone give instructions on how to get this on tradovate desktop? I understand how to create a custom indicator, but where’s the code?
