Max/Min Value for Custom Indicator

[EC_Chris]

Not seeing any posts or info on plotting a Max/Min value for an indicator here really, just stuff on Max/Min for price.

All I am doing is creating a BollingerBand Width and plotting the Max/Min of that indicator over x amount of bars, similar to a Donchian Channel.

Here is the code logic. Everything compiles, but it is just plotting 0 for the Max & Min values

			else if (State == State.DataLoaded)
			{
				max = MAX(Plot0,150);
				min = MIN(Plot0,150);
			}
			
		}

		protected override void OnBarUpdate()
		{
			if (CurrentBar < Period) 
			{
				return;	
			}

			double max0 = max[0];
			double min0	= min[0];
				
			Plot0[0] = (Bollinger(Deviation,Period).Upper[0] - Bollinger(Deviation,Period).Lower[0])/Bollinger(Deviation,Period).Middle[0]*100;
			Upper[0]	= max0;
			Lower[0]	= min0;
						
		}

Hello EC_Chris,

Thank you for the post.

I see that you are passing the Plot0 to the Min and Max but you are setting Plot0 after using Min and Max. Could you try adjusting where Plot0 is being set and see if this resolved the 0 values?

Plot0[0] = (Bollinger(Deviation,Period).Upper[0] - Bollinger(Deviation,Period).Lower[0])/Bollinger(Deviation,Period).Middle[0]*100;

double max0 = max[0];
double min0	= min[0];
		
Upper[0]	= max0;
Lower[0]	= min0;

I look forward to being of further assistance.
