curious trading

Seems odd to me that the top 16 buyers at .025 and .026 did not participate at all in the last few hours of trading (so my screen tells me), as if they were there as blocks only. Yet a few mill went through.

There were also a number of trades of exactly the same small number of units that reoccurred throughout the afternoon, going back and forth at .027. Selling to themselves?

A number of sales of varying sizes ended with 481 or 461, I presume for easy identification.

Just some thoughts for those who understand these things better than me.
