Hi @runyt If you pick up any trading book you will find these patterns under the name tags of Bull Flag, Bear Flag, Pennant and Wedges. But at the time I did not pay any particular attention to these, then few years a go while I was listening a pod cast of Linda Bradford Raschke (market wizard), she mentioned her best performing pattern is the Bull/Bear Flag, and then I started collecting screen shots of every flag I see, and about a year later I found a thread called PIE - Price is Everything by a trader called Redword11 (One of the greatest traders ever lived) he explained the theory behind a bull/bear flag (I will try to explain it below). There are lot of price patterns that work, it is a matter of training your eye and finding a pattern that suits you. If you do a search for " Flag Trading Forex" you will find so much free resources online.
When I am looking for the pattern following is the story I tell myself
