SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you use the @alpacahq/alpaca-ts-alpha SDK correctly when building trading and market-data workflows, so you can avoid guesswork around client setup, streaming, order placement, and data handling.

Core Features & Use Cases

  • Unified Alpaca client guidance: Understand how the single Alpaca client exposes trading and market-data namespaces without losing access to the underlying raw APIs.
  • Safe trading and data workflows: Use ergonomic order builders, pagination helpers, normalized bars/trades/quotes, and real-time streams in the right way for bots, backends, and analytics tools.
  • Developer guardrails: Follow SDK-specific rules for credentials, branded timeframes, typed errors, retry behavior, and REST-only versus streaming runtimes.
  • Use Case: You are wiring a trading bot that places orders, backfills bars, and then subscribes to live updates; this Skill points you to the correct SDK surfaces and the implementation patterns that keep the workflow reliable.

Quick Start

Ask for help integrating or reviewing code that uses @alpacahq/alpaca-ts-alpha, and include the task you want to solve such as placing orders, fetching market data, or opening a WebSocket stream.
