I wouldn't read too much into the SCO value for the same reason that a high RSI value (traditionally indicating 'overbought') doesn't imply prices will come down. I am sure you know this, but very high values being registered for price oscillators (e.g. RSI) is the first thing which happens when a trend reverses - the oscillator moves high and stays 'overbought', and prices keep rising. That is the inherent problem with using oscillators traditionally - work quite well in ranged markets, but fail when a (new) trend sets in - an uptrend in this case (my $0.02).
