Calculate indicator value on close of bar (and not per tick)
28 Nov 2016, 11:52


Hi guys

I am working on an indicator that draws points to indicate highs and lows.

When I add the indicator to a chart, all the historic points are drawn perfectly.

The newly drawn points, however, are a mess, as the indicator does not wait for the new bar to close before adding it.

Does anybody know hoe to get around this.

 

Regards

Hi, you need to write a method that's called on each new bar. See sample below.

using cAlgo.API;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewIndicator : Indicator
    {
        private int lastIndex = 0;

        public override void Calculate(int index)
        {
            if (index > lastIndex)
            {
                OnBarClosed(lastIndex);
                lastIndex = index;
            }
        }

        private void OnBarClosed(int index)
        {
            // Put your logic here
        }
    }
}

I use shorter approach:

 

.....
        [Parameter(DefaultValue = true)]
        public bool CalculateOnBarClose { get; set; }

        private int lastIndex = 0;
 
        public override void Calculate(int index)
        {
            if (CalculateOnBarClose) if (index == lastIndex) return;  lastIndex = index;
            
            // Put your logic here
        }
.....
