Financial charts in .NET? Best library to display a live streaming 1-min stock chart?

Question

We are using C# .NET.

We're looking for a method to display live streaming 1-min financial stock charts.

Need: - Candlesticks - Zoom/pan - The chart scrolling in real time as it receives streaming data

Woud like: - A method to print metadata on the chart (buy/sell points, etc)

We don't mind paying for it, so any recommendation goes!

Answer 1

My research eventually led to these packages:

* StockChartX WPF
      o http://www.freedownloadscenter.com/Programming/Misc__Programming_Tools/Stock_Chart_X_Financial_Chart_Component.html
      o Rating: B.
      o Pros:
            + Very powerful
            + Nice looking
            + Has a WPF version, see http://www.modulusfe.com/stockchartxwpf/
            + Real-time automatic technical analysis updating
      o Cons:No scroll with the mouse (for non-WPF version, WPF version has mouse scrolling)
      o Cost: US$350 (AciveX) to US$529 (WPF)
      o Notes: StockChartX uses a function named AppendValue (series name, date, value). You actually "push" data into StockChartX, so it does not matter where the data is coming from, be it a database, text file, XML file, or real time tick-by-tick data - it all goes into StockChartX the same way, simple, quick, and easy!
