Your signals did not account for new case of virus in USA. And neither did Volente's. He got lucky, and you did not. News moves the markets, not "technical analysis".
My impression is major market signals are one step ahead of the news, that is, news follows the market. Often when I get a strong signal and the market reacts opposite, this indicates a market turning point. So I get a market bullish signal and price goes down, bears have control so that is a signal in itself. But (there is always a "but") market turning points often see chop and signals get smacked around the ears. (Not January 2019, that was a sudden reversal) So in light of Friday market being negative, I had been bullish but not so sure anymore, would not be surprised if we are topping now. In real terms, I'm not buying stocks any longer, too risky imo.
So, trade the news then? And why are you not short then? It should be obvious for most that news are not what moves the markets.
If news does not move the markets, then what does? A head and shoulder pattern that forms after the fact of the move?
I think algos triggered by news would be the minority. I'm not sure how an ago would interpret news without human intervention of some sort.
