Post From: Number of trades charts different than ThinkorSwim's tick charts

I discovered the reason why the charts don't match, but it is up to Sierra chart to make a change. During the premarket prints above the current offer and below the current bid are trades that are being reported late and/or that are off-exchange. Thinkorswim correctly filters these trades out of their charts so that they don't look like the ones SC prints. Both charts match 100% pertaining to OHLC and volume until 8am when the exchange starts to report the late trades and Sierra Chart goes wild. I have attached two files showing with time stamps the difference between the two.
