Short Term Trading Weekend Lounge: 6 -8th Apr, page-56

Bought some APE a few days ago because like others, I'm a bit bored.
It is in long term uptrend, some volume, so worth a punt.
Since I'm in, I look at course of sales daily.
I've noticed that there's an irritating buyer/seller of 1 to 5 or so shares constantly all day, for days.
It seems to have little or no effect on the overall share price - just makes me think someone's playing.
Is this an"algorithm" and what is the purpose?


Have seen it in a few others as well.
