Out of Sequence Trade (SEQ): An "out of sequence"

Out of Sequence Trade (SEQ): An "out of sequence" trade will come in with a price either higher or lower than the current price. This trade is "out of sequence," so the time at which this trade was actually executed is most likely unknown and therefore removed it from the data. This particular trade is still valid, so it will still appear in the Time & Sale. The Time & Sales window will be flagged as "out of sequence."
