C# Programmer - Stock exchange data recording

Project: C# Programmer for Stock Exchange Data recording Expected work load 5-10 days. We would like the programmer to build a small tool to monitor and save real-time stock exchange data (bid ask quotes). The real-time data will be delivered via an API from a Broker, a C# .Net interface for the data is available. ([login to view URL]). The broker we use is Interactive Brokers ([login to view URL]), a demo account and demo tickers will be provided. The programmer should build a simple GUI that displays realtime quotes. The relevant tickers should be imported from an Excel sheet, where the user can add, delete and modify stock tickers (eg. MSFT). The recorded data should be saved in a text file or an Access Database. We will request the full source code. If we are compeletly happy with the work, there will be a bigger follow-up project with a work load of 6-10 weeks.
