EURGBP short term- end of retracement expected

After an A/1 impulsive wave, EURGBP is in a corrective wave.
This correction is a triple combination pattern WXYXZ. So I expect soon a new impulsive wave up B/2. My chart shows the actual channel where the price are moving. A break of this channel and a new high (> 0.78300) would confirm this point of view and give an interesting long.
