This is an Intrinio C# SDK for Real-Time Stock Prices. It provides real-time stock prices via a two-way WebSocket connection. The Intrinio Real-Time Feeds uses the WebSockets protocol to push stock price quotes to clients in real time. The Intrinio Websockets API will send you the last recorded IEX bid/ask/last quotes, even during off-hours. So you will notice that the first quote update will come through immediately upon connection, and it will have an older timestamp. All quotes afterwards are live updates. Intrinio is a financial data marketplace that is restriction-free with self-sign up, and chat support.
Google's App Engine product has been available for developers to build upon since last April, and in that time has been free to all, up to certain resource limits. Many have taken advantage of that capability to build thousands of apps including some now in our directory like the iTunes clone The Cloud Player and the Yahoo BOSS search mashup 4hoursearch. But the most common request from App Engine developers has been the ability to go beyond the initial resource limits. As of today, Google has lifted those limits and will let apps scale beyond those early free quotas.
