Pattern recognition is a popular topic especially with new and evolving traders. I've used pattern recognition to make trading decisions for 30 years. It's not the only way to trade but it's been a very successful method for me and I'm happy to share some insights wiht you.
The Setup: The bullish setup is simple to recognize. Firstly, the trend must be up; that is, our 30 day EMA (exponential moving average) must be higher today than what it was yesterday. The triangle you are looking for must have 4 distinct internal swings, which help define and differentiate the pattern from lower probability trades.
