1. (BEFORE YOU BUY) You want to see this rise well above the .50 retracement and close up there, It can even go as far as .75 extension or spike above it, I do not want to see it close above the .75, if it leaves some wicks behind, no problem, but I really want to see it go into the .75 area and get rejected and fall back down near .50.
2. (GET Ready To BUY) We buy the pull back to .50 area, it may overshoot .50 from panic selling, it could overshoot .50 cause it wants to, the point is to buy .50 or around it, unfortunatly this is an Art, not an exact science. The range to buy is 177 Satashi to 189 Satashi, .50 is sits on 182 Satashi. this setup is forgiving, you dont have to be exact.
3. (Stop Loss) For you short term day traders, set a stop loss at 148 Satashi or lower if you see fit for your style, if it closes below .50 on the retracement, it may be failing.
Let the trade come to you!!! If it does not come to you, it wasnt meant to be, or I am a really bad Analyst :-)
