When SPY / QQQ move 2% or more it's always the question - what to expect tomorrow.

Here is a quick study on SPY and QQQ since 2017. SHORT at open the day after 2%+ pop from intraday low to close. So we buy at open and sell at close the next day after 2%+ green day.

In terms of win/loss. It's ~50/50 but the moves are larger on the downside (shorted in the backtest). What you think we are going to see tomorrow?
