The reason for this is that whether a trade occurred at the Bid or the Ask is based upon a field from the Chicago Mercantile Exchange multicast data feed. Sierra Chart does not make this determination by comparing the last trade price to the Bid or Ask.

You can be assured that what you are seeing is 100% accurate.
