Perfect Indicators started with a finding that looked like a goldmine: EUR/USD on Thursday at 01:00 had closed higher 80.4% of the time. That's the kind of number this industry builds landing pages around.
Instead of a landing page, we built a longer backtest. Re-measured over a decade of data, the same bucket settled at 67.7% — and every other extreme reading shrank toward the coin flip the same way. The 80% was real in the small sample and gone in the large one: regression to the mean, the normal fate of every small-sample extreme.
That became the founding rule: publish the number that survives the bigger test, never the number that sells better. Every figure on this site carries its sample size and a significance flag, because a percentage without them is an invitation to fool yourself.
A seasonality dashboard over 23 years of institutional bank-feed history — how often each hour, weekday and month has closed higher, for 19 markets — plus a strategy board that backtests 5,086 simple seasonality rules after spread and against held-out data, and shows the denominator: roughly 96% of them fail. The board exists to show you the funnel, not just the survivors.
Not a signal service. Not a promise of returns. Not "one weird hour that made traders rich." The FAQ's largest section is titled "What it can't do" — measured in our own data, published before you pay, because we'd rather lose a sale than earn a refund.
Perfect Indicators is built and run independently from Cebu, Philippines — one person, supported by the tooling you'd expect in 2026. Small on purpose: nothing between you and the person who answers the contact form.
