The system is already short UJ from 100.70 on Friday. The price action today is very weak and it looks like the market really wants to see below 100. The 50% Fibo of the big drop from 124 – 75 (2007 – 2012) is at 99.85 and after overshooting to 103.75 we should likely see an overshoot below.
I have gone short as follows:
Short $10/pip USDJPY at 100.33, SL at 100.73.
