Give it a ticker. It tests 600+ strategies against real market data, picks the best-looking backtest, then shows that "winner" data it has never seen. This whole site's founding story, automated.
Crypto pairs (e.g. ETH-USD, SOL-USD) are free and fast. US equity tickers (e.g. MSFT, NVDA, TSLA) pull decades of real, split-adjusted history - may take a moment longer, still guarded by cost/rate limits (rarely refused now - see below).
This calculator's cousin, weaponized: same multiple-testing problem, just run 600+ times in a row so you can watch it happen. Try the free DSR calculator on your own numbers, or join the waitlist to run this against your own private ledger.
