Ending diagonal on Gbpchf

I have some good runs on this pair and its stance to form patterns that I vividly understand makes me stay close to it.

Price is presently resuming the general bullish run which started in 2013. The general trend is Up! 

We saw the end of the 2nd wave zigzag corrective pattern and the resultant up move which broke  the resistance zone (indicated by the blue rectangle) showed that the correction is over and the trend has resumed upside.

Price is showing the end of wave 3 of the motive wave 3 with an ending diagonal which would make us expect a sharp corrective move downside. This resultant corrective move should end between 1.5430 and the support zone (1.5314-1.5280) before the bullish trend resumes.

Any dip below the support zone indicated will be a threat to the bullish trend.
I am expecting more price data/candles to ascertain the next big move
I will keep an update.
