Equity Options

Key Concepts

Introduction

Equity Options are a financial derivative that gives the holder the right (but not the obligation) to buy or sell the underlying Equity, such as Apple, at the stated exercise price. This page explains the basics of Equity Option data in the Research Environment. To get some data, see Universes or Individual Contracts. For more information about the specific datasets we use, see the US Equity Options and US Equity Option Universe dataset listings.

Markets

LEAN groups all of the US Equity Option exchanges under Market.USA, so you don't need to pass a Market to the AddOptionadd_option or AddOptionContractadd_option_contract methods.

Data Normalization

The data normalization mode doesn't affect data from history request. By default, LEAN doesn't adjust Equity Options data for splits and dividends of their underlying. If you change the data normalization mode, it won't change the outcome.
