Strange price/depth movements

[Gringotts Bank]

Stock is TPI.

Top bid is for 18,838 shares at 79c and has been for the last 10 minutes or so.

Since the bid was placed, the "last" SP has fluctuated numerous times between 79 and 79.5. As it goes back to 79, presumably there has been a sale of shares at 79, and yet the 18,838 remains unchanged.

I haven't got course of sales yet.

Anyone know what would cause this? There's bots active.

Must be bots cross trading.

CX and XT. Not uncommon nor strange. Neither the presence of bots.

Doesn't have to be bots crossing.

I use IG market and I reguarly get the XT treatment (i.e. jump the queue) and occassionally get the CX prices. I am not a bot the last time I check (will check again tonight).

Exactly what a bot would say!

Now all that alpha makes perfect sense...

No... this is what a bot would say.
