Hi there!!

Im sorry for me bad english but ill try as good as as i can.

There is an issue with the gekko bot due to recent  changes at the bitcoincharts api.

First the link to the api has changed but there has to be some more changes of the data provided by the api.

Maybe someone of you can solve this issue? I think the invalid code is in the realtime candle fetcher

The gekko source code is downloadable at github:
https://github.com/askmike/gekko

For those of you who dont know this really nice bot:

It has great backtesting features and can also perform live trading on gox, btc-e and bitstamp with crossing EMAs.
