Trader's diary for September 21, 2020. US market and the November presidential election

Investors kept the US stock market from growing, due to being unsure on who will decide on the future US economic policy - Democrats or Republicans.

As a result, the S&P 500 index fell below the previous low and broke down the 50-day moving average.

What to do in this situation?

Wait for a breakout above the three-day high before buying stocks, OR sell after a rebound upwards.
