I was using zenbot for 10 hours to trade on Bittrex using RSI Strategy. The bot error with ouput like this :

`undefined

var parts = x.toString().split('.');
^

Is this bug ? i start the bot again and now, the bot is normal.

There appears to be a fix for this, but it is something that needs to be done after each time an npm install happens.
See #457.
