Post From: Cancel account and issue refund

Perfectly fine for you to cancel and us to issue a refund. No problem. Less burden on us.

However, we would like to know if it relates to this:
Alarming volume discrepancy shown

The only possible reason could be that volume data is getting mapped to the wrong price level. It would have to be an adjacent price level. It is not possible with the volume related market data Chart/Trade DOM columns, or Numbers Bars, for volume to be missed. That is just an impossibility.

But due to floating-point error which should not be applicable with the market you are trading, volume could get mapped to the wrong price level. If that happens it would be an adjacent price level.

It is very challenging dealing with floating-point error:

However, to be clear there should never be missing volume in Numbers Bars as long as the data has been received.

Might help for us to change the map key from an integer to a float.

If you give us the Intraday data file you were replaying, in that post, we can look at it. This is a scid file. You can zip it and attach it here. Instructions:

Once again we are completely fine with you canceling and us issuing a refund. But we want to understand what the problem is even after you go.
