Bullish chart patterns are those that are recognized as potentially leading to an increase in price of the stock. Of the many bullish chart patterns that have been identified, we focus on those that are the most reliable. We have developed algorithms that select stocks based on bullish chart patterns that were identified by William O'Neil in 'How to Make Money in Stocks' as providing a high likelihood of gains over 25% when the stock breaks out from those bullish chart patterns. These links describe our implementation of each bullish chart pattern and hints on how to trade them.
