Well, on Friday the Stochastic indicator, used by some as a change of trend, by others as a buy signal, crossed up past the 20% level. If there is further upwards movement, the MACD histogram will become positive, also often used as a buy signal (although usually only in upward trending charts, which is not the case here).
Daily chart used.
