tradier 0.1.0

This project involves the development of a Rust library for managing trades and market data using the Tradier broker API. The main objective is to provide an efficient and secure interface for executing trades, retrieving real-time quotes, managing portfolios, and accessing historical market data. The library focuses on leveraging Rust's performance and concurrency advantages, enabling integration into high-frequency trading applications and data-intensive financial processing.
