Module contracts 

A Contract object represents trading instruments such as a stocks, futures or options.

Every time a new request that requires a contract (i.e. market data, order placing, etc.) is sent to the API, the system will try to match the provided contract object with a single candidate. If there is more than one contract matching the same description, the API will return an error notifying you there is an ambiguity. In these cases the API needs further information to narrow down the list of contracts matching the provided description to a single element. Contract definitions and related functionality for trading instruments.

This module provides data structures for representing various financial instruments including stocks, options, futures, and complex securities. It includes contract creation helpers, validation, and conversion utilities.
