Interative Brokers: using ibPy to get live market data

External question — Quantitative Finance Stack Exchange Author: user31172 Original post: https://quant.stackexchange.com/questions/37515 License: CC BY-SA 3.0 — https://creativecommons.org/licenses/by-sa/3.0/ Adaptation: HTML converted to plain text; contact email addresses removed. documentation on ibPy is sparse. All I would like to do is request the current price of a security both pre-market and during market hours so that I can make automated trading decision on that information. Something like: get_price("AAPL"....) that returns the current price of AAPL. Any pointers, or documentation links are much appreciated.
