Plotting Buy / Sell Signals On Candle Chart

Question

Hi,I want to plot Buy / Sell / Other Signals On a Candlestick Chart based on certain condition. The signal signs (Say Some Icon Image / UpArrow / DownArrow) should appear above High or below Low of a candle  by a certain Offset value so that user can see it clearly. Please let me know how can I achieve this in Synfusion Winform chart using c#.Thanks,Amit

Hi Amitabha, 
 
Greetings from Syncfusion. 
 
We would like to let you know that the add symbol by using Symbol property of ChartSeries.Style. Please find the code example below.  
   
Code Snippet:  
   




   
for (int i = 0; i < chartSeries1.Points.Count; i++) 
{ 
    var point = chartSeries1.Points[i]; 
    if (point.YValues[3] < point.YValues[2]) 
    { 
        chartSeries1.Styles[i].Symbol.Shape = ChartSymbolShape.Triangle; 
        chartSeries1.Styles[i].Symbol.Color = Color.Green; 
    } 
    else 
    { 
        chartSeries1.Styles[i].Symbol.Shape = ChartSymbolShape.InvertedTriangle; 
        chartSeries1.Styles[i].Symbol.Color = Color.Red; 
    } 
    chartSeries1.Styles[i].Symbol.Offset = new Size(0, -10); 
} 
   
   
Also, we have prepared the sample for your reference. Please find the sample from the below link.

Hi 
Yuvaraj,Thanks
 for your response. I tried as you suggested and the signals are 
appearing on chart. However I want the Buy signal (Green Up 
Triangle  in your example) to be placed below the Low of the Candle And the Sell signal(Red 
InvertedTriangle

in your example) to be placed Above the High of the candle.
 Right now the offset is being computed with respect to the High of 
candle I believe And hence all signals are appearing above the high of 
the candle. Is there any way to achieve what I want ?Thanks,Amit

Hi Amitabha, 
 
We can achieve your requirement “Add symbol in the above high value and below low value based on PriceDown and PriceUp” with the help of ChartCustomPoint in Windows forms chart. Please refer the below code example. 
 
CodeSnippet: 
 




for (int i = 0; i < chartSeries1.Points.Count; i++) 
{ 
    var point = chartSeries1.Points[i]; 
    if (point.YValues[3] < point.YValues[2]) 
    { 
        ChartCustomPoint ccp = new ChartCustomPoint(); 
        ccp.XValue = point.X; 
        ccp.YValue = point.YValues[1] - 1f; 
        ccp.CustomType = ChartCustomPointType.ChartCoordinates; 
         
        ccp.Symbol.Color = Color.Green; 
        ccp.Symbol.Offset = new Size(0, 30); 
        ccp.Symbol.Shape = ChartSymbolShape.Triangle; 
        this.chartControl1.CustomPoints.Add(ccp); 
    } 
    else 
    { 
        chartSeries1.Styles[i].Symbol.Shape = ChartSymbolShape.InvertedTriangle; 
        chartSeries1.Styles[i].Symbol.Color = Color.Red; 
        chartSeries1.Styles[i].Symbol.Offset = new Size(0, -10); 
    }                 
}
