(52.9,3) buy signal on 11/5. Diff went up 9% subsequently we saw a 9% rally. Confidence in new uptrend causing buying pressure. Miners are holding out for a higher price. If 10 Day and 21 Day cross, this a very good uptrend signal. However I would wait at minimum half a day after seeing the cross before entering a long position as I like to see what kind of news is going on before I invest.
