write an external AddON to draw line

Hello turbofib,

Thank you for your response.

So it is the previous session Open, High, Low, or Close that you need to pass to your custom method, correct?

You could create individual overloads for each double or you could pass an Array as you suggested.

Please let me know if you have any questions.

Hello turbofib,

Thank you for your response.

Below is an example of passing the Open, High, Low, and Close of a secondary series to a partial class.

protected override void OnStateChange()
		{
			if (State == State.SetDefaults)
			{
				Description									= "";
				Name										= "TestPartialClass";
				Calculate									= Calculate.OnBarClose;
				IsOverlay									= true;
			}
			else if (State == State.Configure)
			{
				AddDataSeries(BarsPeriodType.Minute, 1440);
			}
		}

		protected override void OnBarUpdate()
		{
			if (CurrentBars[0] <= 2
				|| CurrentBars[1] <= 2) return;
			
			if (BarsInProgress == 1)
			{
				MyMethods.priorSessionsDetail(Opens[1][0], Highs[1][0], Lows[1][0], Closes[1][0]);
			}
		}
	}
	
	public partial class MyMethods : Indicator
	{		
		public static void priorSessionsDetail(double open, double high, double low, double close)
		{
			// your logic
		}
	}

Please let me know if you have any questions.
