Study is a modified version of Tom DeMark’s Sequential study.

260 is currently the floor.  Most of those puts were purchased Friday. Over a four-fold increase in put transactions at the 259 strike.

Algo trades are great teachers!

$200,000 on the 270 call strike, at the open.  At time 14:33:30, 5,000 contracts trade ($530,000 premium).  I remain long SPX.
