GBP/USD is currently in a broadening wedge formation. On Friday, price retested the daily 200EMA and, again, was rejected. Next test of support will be the 13EMA (blue line) which I feel will hold.
I recommend staying out of the GBP market due to the Brexit outcome potentially being released this week. This market will be high volatility, high risk and high reward.
I'm not trading this market until a solid Brexit decision has been made.
