`Add ticker` gives an error

[tmfelwu]

When i try to add ticker, I get the following errror

Traceback (most recent call last):
  File "./coin/coin.py", line 248, in _add_ticker
    i = self._add_indicator(self.settings.get('tickers')[len(self.settings.get('tickers')) - 1])
IndexError: list index out of range

My user.conf file is

plugins:
- binance: true
- bitfinex: false
- bitstamp: false
- bittrex: false
- cexio: false
- gdax: false
- gemini: false
- hitbtc: false
- kraken: false
- okcoin: false
- poloniex: false
- unocoin: false
recent: []
tickers: []

I am not sure what to add in tickers.

That's a regression and my fault, sorry. It should be fixed with this latest commit, which will also do synchronous discovery when it first starts and are no data files yet.

Thanks for the quick fix @bluppfisk
