Orderbook strategies and zipline #1616

Open femtotrader opened 7 years ago

Hello,

some trading strategies use orderbook modeling.

I haven't seen currently in zipline and Quantopian any support for orderbook. It may be interesting to backtest / paper trade quite illiquid assets (penny stocks, crypto currencies...) and have a more realistic execution simulation.

This Quora question https://www.quora.com/Where-can-I-download-historical-limit-order-book-information may be useful to download historical limit order book

Kind regards

Hi, thanks for the recommendation. This is a feature that would be nice to support, but is not something we will likely be able to add in the near/medium term.
