EjChart control supports 10 types of technical indicators.

Bind data to render the indicator

You can bind the series DataSource to the indicator by setting the specific series name to the indicator by using the Indicators.SeriesName property.

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...
      //Initializing Series
      .Series(sr =>
      {
          sr
              .XName("XDate").High("High").Low("Low").Open("Open").Close("Close")
              //Set name to series
              .Name("Hilo")
              .DataSource(ViewBag.ChartData).Add();
      })
        //Initializing Indicators  
      .Indicators(ind => { ind
          //Set HiLo series dataSource to indicator using seriesName
          .SeriesName("Hilo").Add();
      })
        //...
 )

CSHARP

//// Create dataSource to chart
            List<ChartData> data = new List<ChartData>();
            data.Add(new ChartData("2010/7/1", 38, 10, 58, 27));
            data.Add(new ChartData("2010/7/8", 28, 15, 48, 58));
            data.Add(new ChartData("2010/7/9", 54, 35, 85, 98));
            data.Add(new ChartData("2010/7/10", 52, 21, 38, 85));
            ///...
            ViewBag.ChartData = data;

Also, you can add data to the indicator directly by using the DataSource option of the indicator.

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...
     
      //Initializing Indicators  
      .Indicators(ind => { ind
              //Add dataSource to indicator directly
              .XName("XDate").High("High").Low("Low").Open("Open").Close("Close")
              .DataSource(ViewBag.ChartData).Add();
      })
        //...
  )

Indicator Types

Accumulation Distribution

To create an Accumulation Distribution indicator, set the Indicators.Type as AccumulationDistribution. Accumulation Distribution require Volume field additionally with the DataSource to calculate the signal line.

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...
        //Initializing Series
      .Series(sr =>
      {
          sr
              .XName("XDate").High("High").Low("Low").Open("Open").Close("Close").Volume("Volume")
              //Set name to series
              .Name("Hilo")
              .DataSource(ViewBag.ChartData).Add();
      })
        //Initializing Indicators  
      .Indicators(ind => { ind
          //Set indicator type
          .Type(ChartIndicatorType.AccumulationDistribution)
          .SeriesName("Hilo").Add();
      })
        //...
 )

      {
         //...
      })
        //Initializing Indicators  
      .Indicators(ind => { ind
          //Set indicator type
          .Type(ChartIndicatorType.ATR).Add();
      })
        //...
 )

      })
        //Initializing Indicators  
      .Indicators(ind => { ind
          //Set indicator type
          .Type(ChartIndicatorType.BollingerBand).Add();
      })
        //...

      })
        //Initializing Indicators  
      .Indicators(ind => { ind
          //Set indicator type
          .Type(ChartIndicatorType.Momentum).Add();
      })
        //...
 )

      .Indicators(ind => { ind
          //Set indicator type
          .Type(ChartIndicatorType.MACD).Add();
      })
        //...
 )
