In Calculate() method how to identify each bar instead of each tick
07 Jul 2020, 14:09

I am using an indicator to alert me when it is oversold, and using IsLastBar helps me to understand the current bar but I keep getting alert every second that it is oversold, When I have the chart for 1 hour how can I tell to alert me only once and then only alert after the next bar? Thanks

As you advised - Calculate() is executed on every tick. Try checking if the last bar's open time has change since the last tick. This way your code will be executed only once per bar

Could you please share an example ?

Hi naveenwhy,

See below an example

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewIndicator : Indicator
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        var _lastBarOT;
        protected override void Initialize()
        {
            // Initialize and create nested indicators
        }

        public override void Calculate(int index)
        {
            if (IsLastBar)
            {
                if (Bars.OpenTimes.LastValue != _lastBarOT)
                {
                    _lastBarOT = Bars.OpenTimes.LastValue;
                    // Send your alert
                }
            }
        }
    }
}
