Retracement is just a bit above 50% - that's OK in itself (fib is not a perfect science), so below 1.13800 I like this for a short. But there's some minor potential to see a little bit of growth towards 1.15 to burn some shorts before it dumps.
Will see how we go on Monday
If you wanted to be conservative, you could just wait for it to bounce off the bottom of the triangle as part of a support/resistance test, THEN short it - which would make entry around 1.12 on a retrace (pivot points, daily), with TP1 1.08 and TP2 1.05
Otherwise, enter below 1.138, TP1 1.15, TP2 1.10
