That's normal with bots.
The last three trades until 4pm
1 138 3:59:59 pm 15.5 3 $0 1 2 137 3:59:56 pm 15.5 7 $1 2 3 136 3:59:50 pm 15.5 10 $1
IMO - (When accumulating) The bot is programmed to keep the price down on one side selling into the buy in small amounts to accumulate (after buyers dry up) from larger sellers.
It's not devious - it's mathematics in operation at times of doubt/low demand.
