This is an unofficial JavaScript/TypeScript WebSocket client implementation for the Charles Schwab / TD Ameritrade Streaming APIs. It allows developers to interact with TD Ameritrade's services and access streaming financial data programmatically. Please note that this implementation is not affiliated with or endorsed by Charles Schwab and/or TD Ameritrade.

• MIT Licensed: This project is fully open source and available under the MIT License.
• Cross-Platform: It is designed to work in both Node.js and Browser environments.
• Strongly Typed: The codebase is strongly typed using JSDoc annotations for enhanced code quality and autocompletion support in TypeScript.
• Implementation of Official Streaming Data Endpoints: Official TD Ameritrade Streaming Data Documentation
• Derived from proprietary & internally developed quantitative trading and research software.

To install and use this TD Ameritrade Streamer client, you can add it to your project using npm or yarn:

npm install @allensarkisyan/schwab-td-ameritrade-streamer

yarn add @allensarkisyan/schwab-td-ameritrade-streamer

/** Using CommonJS */
const { TDAmeritradeStreamer } = require('@allensarkisyan/schwab-td-ameritrade-streamer');

const tdApi = new TDAmeritradeAPI({
  clientId: process.env.TD_AMERITRADE_CLIENT_ID,
  callbackUrl: process.env.TD_AMERITRADE_CALLBACK_URL
});

/** Authenticate with TD Ameritrade and retrieve User Principals data to make a streaming connection */

/** Get User Principals data */
const { data: principals } = await tdApi.getUserPrincipals();

/** Configure Streamer Connection Options */
