Encyclopedia of Chart Patterns, 3rd Edition
Thomas N. Bulkowski
*Encyclopedia of Chart Patterns* is a reference work rather than a narrative book: it catalogs roughly 75 chart patterns — reversal patterns, continuation patterns, candlestick-style short-term patterns, and event-driven patterns — each documented with identification guidelines, statistically-derived performance data, common failure modes, and trading tactics. Thomas Bulkowski built the book from his own multi-decade personal database of tens of thousands of individual pattern occurrences across real stocks, which is what distinguishes it from purely descriptive technical analysis texts: every pattern entry comes with quantified statistics on how often the pattern actually performs as expected, how often it fails, and what specific variations correlate with better or worse outcomes.
Because this is a reference encyclopedia rather than a linear argument, this entry groups its ~75 individual pattern chapters into broader thematic sections for the purposes of whole-book synthesis, rather than summarizing each pattern chapter individually (see Source Notes). The book opens with methodology chapters explaining how Bulkowski defines and measures a pattern, what counts as a "breakout," how he calculates failure rates, and how to read the statistical tables that accompany every pattern — this methodological foundation matters because the same visual pattern can be defined slightly differently by different analysts, which changes the resulting statistics substantially.
The bulk of the book is organized around pattern families: classic reversal patterns like head-and-shoulders, double and triple tops/bottoms, and broadening formations; continuation patterns like flags, pennants, and triangles that suggest a pause within an ongoing trend rather than its end; shorter-term candlestick-adjacent patterns; and "event patterns" driven by specific corporate or macro events (earnings surprises, stock buybacks, dividend announcements) rather than pure price geometry. For each pattern, Bulkowski reports statistics such as average rise or decline after a confirmed breakout, the percentage of patterns that fail to perform as expected, how often price pulls back to "kiss" the breakout level before continuing, and which visual variations of the pattern (such as narrower versus wider formations) correlate with stronger subsequent performance.
The book closes with chapters on trading tactics that apply across patterns generally — money management principles, how to combine multiple confirming signals, and setting realistic expectations given that even the best-performing patterns in Bulkowski's database still fail a meaningful percentage of the time. The overriding message across the entire encyclopedia is empirical humility: chart patterns are probabilistic tools with measurable, imperfect success rates, not guarantees, and Bulkowski's central contribution is replacing folklore-level claims about pattern reliability with actual measured statistics, however unglamorous or pattern-deflating some of those numbers turn out to be.
Who This Is For
Active technical traders and chart pattern practitioners who want statistically grounded pattern data as a reference, rather than a beginner's introduction to trading or a single unified strategy.
When To Read This
Best used as an ongoing reference to consult pattern-by-pattern before specific trades, rather than read cover to cover in one sitting.
