The Pound has been in a clear channel over the last year. Support can be appreciated by the 13 EMA , and there is a clear rising trendline.
The moving averages 13/50 reflect the uptrend.
Price has reached the significant crossroad touching the 200 MAV.
There could be 2 possibilities from here.
Price Falters
The 200 MAV @ 142.41 has seen price stopped just below for the prior week.
Significant resistance is present above at 1.4575 , with prominent horizontal resistance from early 2015 and mid 2016 , together with the .50 fib retracement of the downtrend from June 2014 to Oct 2016.
From a wave perspective , a possible wave count could see the present price movement look to complete a wave 4 around the .50 fib.
Price Rises
Price would need to have a clear break of 1.46 , and a long perspective to 1.58 may be in order to the next level of significant resistance.
