Online broker TradeKing (www.tradeking.com) today announced a series of new enhancements to its TradeKing API (Application Programming Interface). The API is specially designed to help developers, partners and tech-savvy investors create highly-customized trading platforms and apps, delivering nearly unlimited possibilities for new trading experience for the firm’s more than 300,000 clients.

“Since we launched our open API last July, we’ve seen keen interest from the developer community in using the functionality to create new apps,” said Kevin Delo, Senior Vice President, Product for TradeKing, “We know no two clients necessarily want to trade in the same way, so our ongoing mission is to create an environment that supports innovation and customization. TradeKing has always been about providing tools that help clients trade in the ways that best suit their personal styles. The enhancements to our API further support that goal.”

The TradeKing API provides developers with the resources to create a wide variety of investor applications that integrate securely with TradeKing’s robust online trading platform. Key API enhancements include:

Available Immediately:

• Enhanced option quote and option chains calls.
  • Developers can create apps that let investors pull a list of available expirations, strikes, or a custom option chain filtered by strike price range, expiration dates and option type.
• Retrieval of equity top lists during the trading day, such as top gainers, top losers, most active and highest volume.
• News displays through an API that requests news by underlying symbol or key words.
• Intraday pricing data for chart apps including one- and five-minute rollups of open, high, low, close and volume information.

Coming Soon:

• Real-time streaming market data for stocks and options.
  • Developers no longer have to constantly make requests to get new quotes. Instead, quotes will stream directly into the app.
• Historical data by a date range for a given stock, such as daily open, high, low, close and volume values going back for six months or a year.
• Event-based order status updates allow more timely status updates on any pending orders. Whenever the order executes, a message is automatically sent to the app.
