GbpCad- more weakness in store?

Two days ago I was drawing your attention to "sell zone" level at around 1.7150-1.7160. The pair had a brief spike above and reversed aggressively yesterday, finishing the day exactly on support.

Now the pair is trading on the confluence o supports provided by horizontal and trend line support.
A close under this zone would expose 1.6850 support and the major support at around 1.67

Strategy:
Sell at market
SL @ 1.7160
Target 1 @ 1.6850
Target 2 @ 1.6700
