Does that famous strategy
actually work?
Pick a strategy everyone's heard of and a real market. We run it on years of real price data and show you the one number most tools hide — whether the edge is real, or just luck dressed up as a backtest.
Want to test your idea — tweak the rules, change the market, see if anything survives the validity layer? That's what Kestrel Signal is for.
