GBPUSD going for a pullback^^

As you can notice GBPUSD has been trading in the upper part of the channel in the last days. This means that the bulls are slowly entering the market and might beat the bears. Allso we got a strong rejection at the 1.31000 zone, which we could get a retest of before the pair pushes through the trendline. My opinion is that it wont get that low again so I will probably wait for a flag which is going to tell me that trend continues and enter a long position and im aiming for 1.37000-1.38000.
