Instead of evidence you people really should talk about probabilities or indications instead. Evidence is a way too strong word to use when trying to predict the behaviour of a market.
Evidence can give an indication of what will happen, sometimes with a probability attached.
I think the market is too small for that, too easily influenced/manipulated. TA works better on the FOREX than at this size. Besides, all indicators are _lagging_.
edit: I don't mean TA is not useful but you have to be real quick to react when a whale or other manipulator decides to play and messes up your nice TA.
edit2: still no parabolic SAR from bitcoincharts. any other service showing it?
