We will look into this and do a comparison to another data feed we have access to but we would expect the most likely explanation is that it has to do with filtering of certain types of trades that can cause out of range prices in a chart.
Also it is not going to help to use the Sierra Chart Exchange Data Feed, the data will be the same.
