The above charts show the significance of the 61.8% Fibonacci retracement in Crude and Nifty Futures.
First Crude hit a high of around 148 in July 2008 and a low of 32 in December 2008. The 61.8% Fibonacci retracement of this fall is around 105 which proved to be a resistance for Crude in the last few weeks.
