Beautiful! Thanks for this. I just got out of newbie jail and also wanted to thank Tobbelino for his work as well.
Once I get these up I will definitely send some mBtc your guys way!

I would love to see a better indicator used for the crossover....ideally MACD.
Since we have the two EMA's MACD is simple calculation really...but right now out of my coding talent level.

MACD Line: (12-day EMA - 26-day EMA)
Signal Line: 9-day EMA of MACD Line
MACD Histogram: MACD Line - Signal Line

That calculation using a multiple day EMA is currently out of the scope of the bot because it will only collect the last 144 samples from Mt Gox. This can be extended to 1000 if you change "const MaxSamplesToKeep = 144;" at the top of background.js but at small intervals won't reach that far to collect that amount of data.

Alternatively the calculation could be done over a shorter time period, or the bot would need to be upgraded to store past data somehow or get it from somewhere else.
