This trading method was included in the Forex Nitty Gritty course and although it is a very basic method, it is actually surprisingly effective. The goal is to look for pairs that are in strong upward or downward trends, wait for a pull-back, and then enter a trade if the trend continues.
I've been using this method on the 15 minute charts for quite a while now and it has always performed well for me because these continuation trends occur all the time.
