How to check, if an indicator's value is less than some number consecutively?

[sherazwaqar]

I am writing a strategy in ninja script and the main function of the script is to have the value of an indicator consecutively 15 bars in a range.
For example, if i am using ADX, it is part of the strategy to have ADX below 20 for 15 bars in a row, and if after 15 consecutive times it breaks above 20, the strategy will buy or sell.
I have used loops and some other functions but did not have a working code.
I will appreciate any help in this regard.
Thanks

Hello sherazwaqar,

You could custom code a loop that checks the prior 15 instances. There is also built in method CountIf() that can be used to check for occurrences of a condition. It returns the number of times the condition evaluates true over a lookback.

Thanks for the quick reply, I was trying to use a loop. Code is below

int lvls =0;
int i =0;
while(Math.Abs(fibMC1[i]) < threshold*TickSize)
{
        lvls++;
					
	cr1.cBar = CurrentBar;
	cr1.upTV = DonchianChannel(fChannel).Upper[0];
	cr1.dnTV = DonchianChannel(fChannel).Lower[0];
	crList.Add(cr1);
				
	if(crList.Count > congestion)
	{
		crList.Clear();
	}
	i++;
					
	}
	
	if(lvls >= congestion)
	{
		int start	= crList.Count;
				        DrawRectangle("Congestion",false,lvls,High[congestion]+TickSize,0,Low[congestion]-TickSize,Color.Blue,Color.Gold,4);
			}

It was working fine, when i was using it on ES CME Index Futures ETH, and when I try to use it on CME Index Futures ETH or 24/5, the indicator does not return any value.
I have set

if(CurrentBar < 200) return; a

I was loading 100 days of data for a 3 min chart.

Error in output windows is

Error on calling 'OnBarUpdate' method for indicator 'FibSRV3' on bar 200: barsAgo needed to be between 0 and 255 but was 256

I will try to use CountIf method.

You are checking for a range over a lookback period. Use the MAX() and MIN() methods.

CountIf() will likely do the trick. A quick example of a for loop you could use to check for consecutive conditions:

protected override void OnBarUpdate()
{
if (CurrentBar > 15)
{
	int myConditionCounter = 0;

	for (int x = 0; x < 15; x++)
	{
		if(ADX(14)[x] < 20)
		myConditionCounter++;		
	}
	
	if (myConditionCounter >= 15)
          Print("We have " + myConditionCounter + " occurrences of our condition");

         myConditionCounter = 0; //Resets back to 0 after we access.

}
}
