tdameritrade-ext 0.0.2

This package extend from https://github.com/timkpaine/tdameritrade.

Information

This package extend from https://github.com/timkpaine/tdameritrade I crawled data options from TD Ameritrade API with thousand requests by hour and my application has generated over 11k tokens in the last few hours when I use tdameritrade package maybe when I send a get request to TDA then a token generated so TD Ameritrade API team notice me. Then I used redis to keep token and using it in 30minute before re-generated. I only modified session.py file and keep others. Bonus, I created 2 methods to get history stock price and options straddle as Yahoo Options.

Installation

pip install pip install tdameritrade_ext --upgrade
