Writing Data to CSV

api.key

Please remove this API Key now.

It's now public and everyone can use it, if it's still valid.

The problem is, that your data has not they key 'closed'.
dict = {'Date':data['date'],'OPEN':data['open'],'HIGH':data['high'],'LOW':data['low'],'CLOSE':data['close'],'VOLUME':data['volume']}

I am not familiar with pandas, but I guess there is a technique to avoid problems with missing data.
In science they have to fight with this issue everyday. Crappy data, which is sometimes not valid or it's completely missing.
