API client for Robinhood

fast_arrow

A robust yet simple API client for Robinhood.

   

example

from fast_arrow import Client, Stock, OptionChain, Option

#
# Oauth2 authenticate with Robinhood
#
client = Client(username=username, password=password)
client.authenticate()

#
# fetch the stock info for TLT
#
symbol = "TLT"
stock = Stock.fetch(client, symbol)

#
# get the TLT option chain
#
stock_id = stock["id"]
option_chain = OptionChain.fetch(client, stock_id)

#
# let's get TLT options (calls and puts) for next 4 expiration dates
#
oc_id = option_chain["id"]
eds = option_chain['expiration_dates'][0:3]

#
# get all options on the TLT option chain
#
ops = Option.in_chain(client, oc_id, expiration_dates=eds)

#
# merge in market data fro TLT option instruments (ask, bid, delta, theta, etc)
#
ops = Option.mergein_marketdata_list(client, ops)

install

Install the package from pypi

pip install fast_arrow

philosophy

fast_arrow is a Robinhood api client, not an automated trading system. Thus, the goal is "keep it simple stupid".

Robinhood as an API has a few different core objects,

• instruments (Option, Stock)
• marketdata (OptionMarketdata, StockMarketdata)
• positions (OptionPosition, StockPosition)
• orders (OptionOrder, StockOrder)
• account stuff (that I'll build for later)

fast_arrow expects that users want to merge these core objects. For example, fetch Apple, Inc (Stock) quote data (StockMarketdata) to display the current price per share of $APPL stock.
