Create a MACD function in C#

Need to create a MACD (Moving Average Convergence Divergence) function in C# that can be connected to a live stock trading bot and integrated with historical data to backtest. Function must have variable input parameters and time intervals, and output values must be chartable. Bonus for a vb.net version as well. I have 2 other projects for similar functions under my profile, bid on those as well if you are experienced in this area.
