Wondering if strawfolk have any insights to share on why I often see market orders in triplets all for a single share e.g.

I get the idea of buying a share to move it from a watch list into your holdings to take a "cognitive step" towards investing in a stock, but I see this particular triplet behaviour regularly and it's making me wonder if there's something else going on here rather than three unrelated orders e.g. some sort of trading algo or other common practice behaviour?

Just curious :)
