I'm going to try it again tomorrow, if the market stays green. I WILL FIND THESE MM AND END THEIR EXISTANCE FOR OUTSMARTING ME, IF THE MARKET STAYS GREEN AND RALLIES.

I'm just messing with you.  Green futures result in gap ups at market open, gap up sells off to fill gap which causes prices to come down.  Red futures cause gap down at market open, gap down induces buying to fill the gap, causing prices to rise.  That is the phenomenon you're seeing.
