Chart & Candlestick Patterns

The classical chart-pattern and candlestick catalogs, with honest reliability data.

The classical pattern catalogs: chart formations measured in days to months, and candlestick patterns measured in bars. Japanese candlestick analysis reached the West through Steve Nison in 1991; the chart-pattern canon runs from Edwards & Magee to Bulkowski’s statistics. Reliability varies widely by pattern and context, and the pages here carry that data honestly.
