Take a strategy people swear by, take any stock or coin, and see what it would've done across years of real prices, next to just holding. About a minute, start to finish. It reports the past; nothing here predicts the future.
Most published backtests quietly cheat in one of three ways: they let the rule see the closing price it then trades on, they compare against a price-only index while the strategy collects dividends, or they show you the one ticker and time window where it worked. This tool does none of those — and we published the time our own test made that first mistake and inflated a result by 11 percentage points.
We test one strategy people swear by and publish whatever the data says — including when it says the strategy doesn't work. Free, no pitch.
