Do you notice a problem at the moment? We would not expect that you would. If this problem occurs at the time there has been some packet loss, that would explain it.

There can also be differences just simply due to subtle timing differences when those two Trade DOMs are updated. This is also a likely explanation.

Some packet loss which is usually very small, does occur and we have been persistent with about Barchart about this. We plan to follow up with them again and be more forceful. We are getting very tired of it assuming this is the reason for the problem.

Otherwise we do know the data is 100 percent correct as long as there is no packet loss. There was some packet loss for today during the 9 AM hour. For CBOT it was 0.002%. So you can see it is very small.

So this means that there could have been a few momentary instances of this. But you should not notice any difference during any other hour today. At any other time today we are certain the data is 100 percent complete.
