Real charts from the last five years, cut at the moment a textbook pattern finished forming. Call it: higher or lower a few days later? Then see what actually happened, and how that pattern has done on that coin. Most people learn the same thing: a pattern on its own is close to a coin flip.
Every round is a real occurrence from the 25 largest coins, picked with the same rule as our pattern statistics: the chart stops at the bar where the pattern could first be seen, not where it looks best in hindsight. Your score stays in this browser.
