This one's for Seth, Binwood or anyone else who has been doing this a while.

I remember vaguely many years ago where a broker or someone in the industry mentioned the significance of 1 share trading through under the
S.E.A.Ts system.

Something to do with broker signalling to other brokers that they're buying or selling, setting up for the algos? Basically signifying it wasn't retail traders.

If I look below I see the 1 share pinging through then further up there's a couple of trades for exact same amount 5,201 which would indicate an algo being set to accumulate within a range.

Does anyone have a more detailed explanation or is my memory playing tricks on me, it was mentioned quite a while back (nearly 20 years or so) and I was trying to remember the significance or any proper explanation.
