Looking For Short Opportunity on Descending Triangle

Pound on defensive due to political turmoil. However, it is pretty flat across against its peers. Market has not fully price in for the political risk. However I am still bearish on pound. If price break below the support level I will look for short.

Reward to risk for this analysis is 5 : 1

Nevertheless, there is a chance of reversing upwards too. If market break above 1.6723, I will look for long opportunity.
