I feel this way as well. Stats are always taken in an environment and once the environment changes, I think so would those stats.
The playbook is also different because of the interest rate environment that we are in. Everything I keep watching on macro stuff states that the market sees lower rates for 2023, since the market is convinced the Fed will have to pivot. But what if the rates don't come down?
Trading this rally has been a bitch because I'm just so bearish. Luckily I can see a long setup for a day trade, but zooming out far enough has me shaking my head. Its nothing but rate rises and high paying job loses in the tech sector. The huge 517k number that came in on Friday I have seen be attributed to an aberration with how the numbers are counted, or simply people working multiple jobs. The hourly wage hasn't ticked up, and other metrics point to this number being not reliable.
Anyway, the stats thing and how the data is collected if huge. For example, something as simply as buying at a 50% retracement works, in a bullish environment. But if you could redo stats with a simple filter accounting for trend, I'm sure all the stats or how often trades work would change measurably.
