Nasdaq Log doesn't use delimiters?
Trade prices without volume is not a trade at all. There were no volume numbers in your post, therefore the data is anomalous.
I don't (won't) use TOS on my current computer. But I get my data from exactly the same place as TOS gets its data -- TDA.
You use TOS, so show me an intraday chart having a UGAZ spike of $4.50 straight up and right back down.
The terms straight up and right back down and big volume are relative to the chosen time interval, and also to volume. What was that interval? Tick, minute, hour, what? What was the volume?
--------------------------
This would all be so much easier if posters included visuals (AKA charts) along with their price/volume comments and questions. It would also be nice if there were dates assigned to the original observations of up and down spikes. The date of the comment was Sunday. On what date did the spikes occur?
Without more and better information, there's no value in commenting on this any further.
