US Equity Indices Likely To Markdown

I anticipate a large decrease in liquidity across financial markets before the end of this week.. I am specifically targeting the S&P 500 due to its 2018 price movement, recent block trades in $SPY & its general volume flow, as well as the $US500 correlation with various other securities over relatively large timeframes. My options holdings consist of $SPY puts, $UVXY calls, $USO puts, $TSLA calls, and $GST calls.
