The E*TRADE C++ SDK is an additional tool that helps to build trade applications directly through E*TRADE without installing additional software components. The section of news and the developers forum could be useful for programmers who want to learn with others before partnering with E*TRADE. With the developer platform, users can integrate portfolio data, market information, and trade execution.
API service provider Mashery (a ProgrammableWeb sponsor) has launched a new app directory at SXSW which features apps built on Mashery hosted APIs. It’s a great thing for three distinct groups. First, it helps the API providers who partner with Mashery by encouraging API usage through the apps. Second, it helps app developers seeking to build an audience. Third, it helps consumers that might be interested in finding an app that uses a particular API. Granted, those would be your super savvy mobile app consumers, but that doesn’t seem so far fetched after a week at "spring break for geeks."
