This chart purposely hides the candles that you are not suppose to buy and only shows candles that are "buys". There are other indicators that clearly state "buy". With SQQQ being the inverse of S&P 500, this means that now would be the ideal time to think about protecting your portfolio by buying put options.
I have vertical lines above the dates that have "buy" on the indicator. As you can see, the indicator is correct most of the time.
