Those are "bad ticks" -- they occur in all the data feeds. No faking going on. It is easy for a bad T&S # to get into the stream, some data providers have less of them than others. Probably a permanant fact of trading life.

Robert:

It sounds as though an erroneous trade price came across the data. Subsequently, the trade print was reversed and removed as the high of the day. However, since historical data (5 min, 15 min, etc.) is saved separately on your data suppliers hard drive, the high-low for each period is not recalculated.

I can't be sure on this, but this is the most likely scenario to me. Other ideas, anyone?
