P123’s Ultimate at $200 /mo has 20 Y of backtests,

Wow.

And it's not 20 years of backtest, I believe. It's back to 1999.

I was grandfathered in from my stockscreener123 account at $20/mo, when they folded SS123 into P123. I could backtest all the way back to 1999.

Cancelled it a few years later because it wasn't worth $20/mo to me.
They were pushing to get you to sign up for blackbox screens that other subscribers had invented. At an additional cost.

Their database seemed to be really really good, totally free of survivorship bias. But $2400/year is a lot.
