Yeah I'm also wondering about the not seeing the buy/sell (^ and v)
I think this ties in with me having to add extra values to those two series.
I finished that stuff off drunk last night...but that charts show it would have made profit 

I've updated the notebook now to use OHLC and it works.
I took the code from load_bars_from_yahoo() so we can use stuff like data['BTC']['open'] within the handler.
Works well.

Almost there....
I also agree that we need to use a better data source and that should probably be bitcoincharts.

Bots just puke up machine language.
Time to talk to some humans down the pub.  Sunday Roast!!!
