April 2022 Summaries

Composer is a trading platform that allows retail investors to build portfolios using sophisticated investment strategies with a no-code visual editor. Founded by Benjamin Rollert, Ananda Aisola, and Ronny Li in 2020, Composer aims to make dynamic portfolios accessible to investors at all levels by providing off-the-shelf templates and breaking down the trading strategy process into building blocks that can be combined infinitely. The platform partners with Alpaca Broker API to offer retail investors access to systematic investing strategies that would have previously required coding skills to execute. With its intuitive software, Composer enables investors to monitor strategy performance in real-time and automatically execute trades on their behalf.

The Alpaca Trade SDK provides four language-specific APIs in Python, TypeScript/JS, C#/.NET, and Go, allowing developers to access the latest functionality of Alpaca APIs. The SDKs have been updated with new features and improvements, including the removal of Market Data V1 capabilities, support for multi-symbol requests, and enhancements to data streaming connectivity. Notable changes include breaking changes due to API updates, improved error handling, and increased performance. The SDKs are designed to be easy to install using language-specific CLI commands, making it simple for developers to integrate Alpaca APIs into their projects.
