collab can not connect to server

[macd2]

im running the example:

import matplotlib.pyplot as plt
from pandas.plotting import register_matplotlib_converters

from jesse import research
research.init()
import jesse.indicators as ta
eth_candles = research.get_candles('Binance', 'ETHUSDT', '4h', '2019-07-28', '2019-09-28')```

But im getting: 

```OperationalError: could not connect to server: Connection refused
	Is the server running on host "127.0.0.1" and accepting
	TCP/IP connections on port 5432?```

Please ask questions either in the forum, or the discord server's support channel.

Are you running this on Google Collab? If so, it won't work. You don't have PostgreSQL in there. It only works with Jupiter notebooks on your local machine
