Still have about 170 pips till it reaches the top of my expected zone. Of course this is far from an exact science. Even so, I'll stick to cautious intra-day trades until it's time to to go long.
Expect to increase as we approach PRZ. We could also see key supports to be tested multiple times before reversing. For that reason, I recommend being cautious until GBPUSD makes HH & HLs .
