I have use a fibonacci retracement to scale that correction zone and only to findout that, the correction zone has a descending resistant trendline...which gives us 2 confirmations; 1. Fibonacci zone 50.0 - 61.8 or Psychological area / respected zone 2. 3rd touch on Descending Resistant trendline.
Please follow me for more of these...and please leave a comment and tell me what you think...i'll love to engage further...
