Interesting SWF Portfolios, page-2

Some people buy and then keep one position as a pseudo watch list which anchors to their previous price so they can check the graphs again to see when to trade it next. I know I've done that before and it works surprisingly well for stocks you keep entering and exiting. Did that with SSG quite a bit.

There are a lot of YOLO stock punters so not entirely sure if such micro data would give you any indication on trading activity. @danbradster posts the ASX trade volume which is a good proxy for that.
