When the closing price finishes below the first support trend line then Go short. For extra confidence wait for the break of the second trend line . Big Pip collector. My target would be at least 127 of the fib extension.
We are about to Enter the Sell set up. I personally went short on the first support break out however on retracing from the 2nd support I got stopped out however, it does look like it is coming back for a second try which I think means it will break at 4PM GMT.
