That's a sign natural market forces are pushing the price higher. The auto-bots with the algorithmic selling only kick in late in the day, and the larger parcels are used to stop the price moving higher.

The algorithms can work out the demand on the buy and sell side and up the block trades and trickle trades accordingly. Part of these transactions also involve buying and selling to self or a related party, so no matter what the demand is the price can usually be contained (have a look at the 5mil day that attracted a new holder and ask yourself why the price didn't go through the roof that day)!
