YahooDataManager ydm = new YahooDataManager(); CSVDataProvider cdp = (CSVDataProvider)ydm[“MSFT”]; //Add stock lines to main stock view fc[0].AddFormula("FML.NATIVE.EMA(10)"); fc[0].AddFormula("FML.NATIVE.EMA(50)"); fc[0].AddFormula("FML.NATIVE.EMA(200)"); fc[0].AddFormula("FML.SAR(10,2,20)"); //Add indicators to stock chart fc.AddArea("FML.MACD(26,12,9)"); fc.AddArea("FML.RSI"); //Apply build-in stock chart skin fc.SetSkin(FormulaSkin.CyanGreen); //Bind stock data fc.DataProvider = cdp; //Output the chart to webbrowser fc.SaveToStream(Response.OutputStream, 640,480);

  5. Formula script sample: Below code is copy from basic_fml.xml MACD: DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG); DEA : EMA(DIFF,M); MACD : 2*(DIFF-DEA), COLORSTICK This formula will create three line DIFF,DEA and MACD. Formula compiler can edit “native-en.xml” and compile the script to Basic_fml.cs and basic_fml.dll, basic_fml.cs can be compiled to Your main program, basic_fml.dll can be load on runtime.
