EurGbp power of three drives pattern

The purpose of this uptrend was "Three drives pattern", which was formed from 2009 to 2014. The first target of this movement - 0.9300 , second target - 0.9790. In August 2017 first target was achieved. Now eurgbp is on its way to the second target. A flag is currently being formed. The flag is a trend continuation figure. The basis for the formation of the flag is the same of "Three drives pattern". At the moment, the price is at point b. When forming a reversal pattern, you can sell eurgbp. I guess point 3 is located in the region 0,8420. From there, the upward movement to the last target will begin. Good luck!
