Crazy SPY Tick Volume, Bots Taking Over!

Have you seen how $SPY volume hits the tape? On the tick charts below in about a second tick volume increased from 0 to about 40,000 shares (and SPY is trading at 92 so it's not cheap). The volume triangles were so perfect that I made boat sails out of them in MS Paint for your viewing pleasure. It's weird that I didn't see any massive red volume spikes. WTF? The bots are taking over!
