The Constant High[0] changes during the loop

[MokhtarVerdi]

Hello
have a nice day
The length of the last candle is 10.
It is stored in a variable called BarLength.
The BarLength should be constant in the loop, but it changes as you can see in the photo.

        protected override void OnBarUpdate()
        {
            //Add your custom indicator logic here.
            if (Bars==null) return;
            
            NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType barsType = 
            Bars.BarsSeries.BarsType as NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType;
            
            if (barsType == null) return;
            
            int BarLength=(int) ((High[0] - Low[0]) / TickSize);
            

            for (int i = 0; i <=BarLength; i++) 
            {
              Draw.Text(this,"myTaga-"+i.ToString(),High[0].ToString(),i,High[i],Brushes.Yellow);
              Draw.Text(this,"myTagb-"+i.ToString(),BarLength.ToString(),i,Low[i],Brushes.Yellow);
            }
        }

I wrote the programming code in a different way, but the problem is still there, I think there is something wrong with my code.
Because I feel instead of the last candle, Indicator reviewed daily High and Low

        protected override void OnBarUpdate()
        {
            if (Bars==null) return;
            if (CurrentBar<100) return;
            
            
            Draw.Text(this,"myTag-01",BarsArray[0].GetTime(CurrentBar).ToString(),1,BarsArray[0].GetHigh(CurrentBar),Brushes.Red);

            for (double Price = BarsArray[0].GetHigh(CurrentBar); Price >=BarsArray[0].GetLow(CurrentBar); Price-=TickSize) 
            {
              Draw.Text(this,"myTaga-"+Price.ToString(),Price.ToString(),0,Price,Brushes.Yellow);
            }
        }

Hello MokhtarVerdi,

Use prints to understand the behavior.

Below is a link to a support article on using prints to understand behavior.

https://support.ninjatrader.com/s/article/Developer-Guide-Debugging-using-Print-and-TraceOrders

Print the time of the bar, print BarsArray[0].GetHigh(CurrentBar) and BarsArray[0].GetLow(CurrentBar) one line above the for loop.
Print Price within the logic block of the for loop.
Include labels for each value.

Save the output to a text file (right-click the output window > Save as) and include this with your reply.
