Hi FTSE,
I've had this on my watch list for a while now but I've been looking dor a possible short setup. Infact I posted a chart of this on this thread a couple of days ago.
As for pullbacks a fall below the previous basing lows would mark an end to the present uptrend.
You could overlay Fibs on a chart to give you an idea of where ther might be potential support, moving averages will do the same.
put a 100MA on it and see if 52.70 is bouncing on it. If it was dow, I'd say a "W" bottom, reached target, and if it bounces on the 100MA here, it goes up.......
