How to pass Bars from a cBot to an Indicator

Hi,

When you run a cBot it gets the available data on your chart as Bars object.

That same object is shared with indicators that you use inside your cBot or on your chart.

You can't select the bars in UI parameters, a Bars object represent a time frame/period price data.

You have to use TimeFrame parameter and then your indicator/cBot can load that time frame bars.

RE:

Many thanks for the reply. I currently have:

using System;

using cAlgo.API;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class IndicatorTest : Indicator
    {
        [Parameter("Bars")]
        public Bars bars { get; set; }

        protected override void Initialize()
        {
            try
            {
                Print("Starting");

                Print("Bars - {0}", bars);

                Print("Started");
            } catch (Exception e)
            {
                Print(e, e.StackTrace);
            }
        }

        public override void Calculate(int index)
        {
        }
    }
}

I am wondering if you can share an example come on how 

GetIndicator(Bars bars, Object[] parameterValues)

is used?

I am trying to create multiple indicators for multiple symbols within the bot. Each indicator will get one timeseries of bars.

Hi,

You can do it like this:

using System;
using cAlgo.API;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class IndicatorTest : Indicator
    {
        [Parameter("Bars TimeFrame")]
        public TimeFrame BarsTimeFrame { get; set; }
        
        private Bars _bars;

        protected override void Initialize()
        {
            try
            {
                _bars = MarketData.GetBars(BarsTimeFrame);
                
            } catch (Exception e)
            {
                Print(e, e.StackTrace);
            }
        }

        public override void Calculate(int index)
        {
        }
    }
}

Now, to use it on a cBot or another indicator:

Indicators.GetIndicator(TimeFrame.Daily);

It means it will use daily bars.
