AmeriTrade API

The AmeriTrade API allows developers to enable their software to connect to TD AmeriTrade. Anyone with a TD Ameritrade account has access to the API, and you can use API features such as submitting a trade, canceling a trade, modifying a trade, viewing historical stock data, streaming news and actives, obtaining your account information, and getting mutual fund or EFT data. You can become a partner, too, to expand your application's reach. Contact to obtain more information and documentation.
