Did anyone buy this dip? What made you pull the trigger?

With all the market chop lately, I got curious about simple dip buying setups, backtested a few and the result was kinda funny:

3 red days can produce pretty big wins. 20 day low can hold across diff tickers..

Not saying this is a signal for right now, just thought it was interesting given the recent dips

Curious for swing setups, do you care more about biggest return or something that works across more stocks?

Cheers :P
