    symbols: ["AAPL"],
    startdate: "2012-04-06",
    interval: "1min"
  }).then(function(data) {
    handle(data);
  }).catch(function(error) {
    handle(error):

  });

Notes

For highly repetitve calls where streams are not used, generate your own endpoint and GET from it directly via getDataFromEndpoint(endpoint). This is far more efficient.

For migrating from 1.0.0 to 1.1.0, getStockData is now getQuotesForSymbols. Also, the constructor no longer takes symbols and fields. Generate an endpoint and use getDataFromEndpoint(endpoint) if static use is necessary.

The following functions are built out, but have not obtained useable data from TradeKing.com: getNews getArticleById searchOptionsForSymbol
