Dealer Futures Flow 8/14/19

Scatter plot titled Est Futures Trading Required of No. Futures vs S&P 500 Price with a red star near 2850.

Here is a chart estimating the futures action with the S&P500 at 2850. If markets head lower it looks like dealers will sell more futures, compounding the move down.
