You cannot make the kind of comparison you are. Charts based upon number of trades per bar inherently will look different between services and software due to different Session Times and/or the starting time at the beginning of the chart.

Everywhere we look, we see differences which means there is a problem with the starting time for the chart bars.

The Sierra Chart Exchange Data feed is fine. There is no doubt about that whatsoever. Anyone else using the data feed is welcome to comment on that. There is another explanation here.

We will not accept the analysis that you are doing because it is not a trustworthy and reliable method.

Open a chart for the ES market and set the chart bars to 5 minutes per bar and verify you see the [M] after the symbol. Add the Volume study. Let the chart run in real-time for about 10 minutes and then re-download the last 10 minutes of data. Do you notice a change with the OHLC values or the Volume?

We are doing this test now.
