Exchanges Reference Issue

[gwdp]

I'm getting reference issue with 'this' in exchanger class...

Output:

    if (err) throw err;
                   ^
TypeError: Cannot call method 'add' of undefined
    at EventEmitter.trader.trade (/Users/username/gekko/exchanges/mtgox.js:21:16)
    at EventEmitter.emit (events.js:117:20)
    at advice (/Users/username/gekko/methods/exponential-moving-averages.js:198:22)

    at process._tickCallback (node.js:415:13)

and the same will happen on sale...

Node Version:

v0.10.3

Thanks for reporting the issue, it is indeed a pretty severe bug for a tradebot...

Experienced the same issue myself before I saw this pull request and fixed it already by binding the context inside the exchange class.

Thanks for reporting it though!

Github should message me on a new pull request imo..
