This page states how the numbers on this site are produced, what they assume, and what they cannot tell you. If a figure cannot be reproduced from a stated method, it should not be here.
Every claim on this site carries one of these five labels, so you can tell textbook consensus from our own measurement without inferring it from tone.
A fact that is uncontested and verifiable outside this site, such as a contract size or a formula's definition.
What technical-analysis textbooks assert about a pattern, reported as their claim, not as something we have verified.
How a rule was defined and detected: the exact condition over open, high, low and close.
Our own output from running that rule against the dataset, always shown with its sample size.
Too few occurrences to say anything reliable, or not measured on this dataset yet. Said plainly rather than implied.
Pattern research is generated at build time from stored rule definitions run over a canonical price feed. Every published figure carries the engine version and the data vintage it came from, so a number can always be traced to the run that produced it.
Detection is mechanical. A formation is a condition over open, high, low and close, with a trend filter applied before an occurrence is counted. Counts below the sample floor are reported as unresolved rather than dressed up as findings.
A quantitative trading research site with tools attached. Most trading content explains a method and asserts that it works. This site defines the method precisely enough to run, tests it against historical data, and reports what came back, including when the answer is that nothing did.
The calculators exist because a trade has to be sized before any of the research matters. The research exists because a number without context is just a number.
Corrections are welcome and get published. If a figure on this site is wrong, tell us which page and which number.
Risk disclosure
Everything on this site is educational material, not investment advice, and nothing here is a recommendation to buy or sell any instrument. Leveraged trading can lose more than the amount deposited. Past performance and historical research do not indicate future results. You are responsible for your own decisions and for verifying any figure before acting on it.
