What the test did and did not do point-in-time data checked for look-ahead net of real costs tested out of sample Almost nobody publishing a backtest says which of these they did. We list the ones we failed as well as the ones we passed.
Tested 2026-06-23. The same treatment,
applied to every other system, is on the test bench .

Trading Truth is an independent research publication — the referee nobody can buy.
Built by Nathan Joel — a retired founder who tests markets for the love of it, who decided to make the studies
public — no fund, no kickbacks, nothing we’re paid to promote. Everything here is general market commentary for education and entertainment. It is not personalized investment
advice and not a recommendation to buy or sell any security. Our audits are our honest opinion backed by factual
backtesting; the people we audit may disagree. Backtested results are hypothetical, do not represent actual trading, and
carry biases we work hard to remove but cannot eliminate entirely. Past performance guarantees nothing — and trading carries a real risk of loss; selling options in particular can lose far more than the premium collected . It's your money — we don’t touch it, and we won’t tell you what to do with it.
