are these small trades bots?

Can someone explain the trading activity of TRS? It looks very odd to me, as there is usually a large number of small parcels, both buyers and sellers, some with exactly the same parcel amount repeated over a range of prices. Is this what they refer to as bots? Would it be plausible one fund is trying to push the price up with bots, whilst another pushing it down? Seems all very artificial to me.
