I was browsing some shares and accidentally clicked on a 5 minute intraday tab. I noticed this peculiar volume pattern and wondered what may have triggered it. I checked a few different shares and even a foreign one and to my surprise similar stair-climbing patterns existed. Thinly traded shares don't have it and it seems to kick in at 3.
What was special about the 3rd of June (a Wednesday) or is this a glitch in the matrix (or my brokers data feed)? Is this some sort of algorithmic artifact? Or related to option expiry? I'm curious!
