Thanks for the reply Panagiotis.
Yes, I decided to cheat this limitation by creating a wait thread for event of closing.

But this only works when changing parameters / timeframes / symbols and not CloseEvent.

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

using System.Threading;
using System.Threading.Tasks;

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class TestWaitClose : Indicator
    {
        [Parameter(DefaultValue = 0)]
        public int RESET { get; set; }

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

        private static AutoResetEvent InitEvent;
        private string Status;
//......................................................        
        protected override void Initialize()
        {
            if(InitEvent != null)
                InitEvent.Set();    // send signal to previous instance of the indicator
            else
                InitEvent = new AutoResetEvent(false); // first start
            
            Status ="Init";
            
            startWaitResetHandler();
        }

        private async void startWaitResetHandler()
        {
            await Task.Run(() => InitEvent.WaitOne());
            
            // OnClose indicator operations ..
            Status ="DeInit";
            Console.Beep(1000, 200);
        }
//......................................................
        public override void Calculate(int index) 
        { 
            ChartObjects.DrawText("StatusInfo", Status, StaticPosition.Left);
        }
    }
}

@PanagiotisCharalampous:

Are there any plans for this?

We have a Panel control we place on the chart. This panel control can have multiple indicators that add their own button/checkbox/whatever to the panel. When the indicator is deleted from the chart, the whole Panel Control is removed as there appears to be no way to execute code when an indicator is deleted nor does there appear to be any sort of "indicatorremoved" event for the chart so we can tell our panel control to remove the child control that was added by the now-deleted indicator.
