Getting Quotes from eTrade API in Python3

Question

I'm trying to get quotes from the etrade API. I'm able to list accounts, get transactions, but not get quotes. I've tried removing the accounts and transactions api calls but it makes no difference. I get an "oauth_problem=signature_invalid" response. Any ideas what I need to do differently?

Not sure if you figured this out but you had a typo here:

    resp = self.session.get(quote_url_template, params={'format': 'json'})

Should be using quote_url, not quote_url_template
