I'm tending to go with prediction #1 with a bottom at 775$ on BTCE having failed the double top confirmation at 848$.
I expect some strong resistance around 840 as it is near the upper border of a big downtrend channel and the 12-10 to 12-18 correction 0.618 retracement line. Let's see how it turns out.
My goal was to combine MACD and PSAR into one easy to read line, hopefully I succeeded. PINE script available here: pastebin.com Questions or comments are welcome!
