1. Why do you ignore the sell signal of 2012-12-21? "Low power" signal?
2. Why do you ignore again the 2012-12-27 sell signal?
I ignored those signals because the macd was spiraling (there wasn't a strong angle of attack on a crossover) along with no RSI signals and no clear support or resistance levels. We finally reached a resistance level at 1050 area and my RSI and MACD along with low volume indicated this resistance would not be broken and a reversal was in store.
Thanks and please, don't give up sharing these interesting ideas :) !
