resetting ray position

Hello brucelevy,
Thank you for your patience.
Below is code that would draw a ray on the first instance and then set it to the second instance (or in my example that last instance of the signal). My example uses Close[0] > SMA(20)[0] as the signal.
Code:public class TestRay : Indicator { #region Variables private int instance = 0; private int barOfInstance; private IRay myRay; #endregion /// <summary> /// This method is used to configure the indicator and is called once before any bar data is loaded. /// </summary> protected override void Initialize() { DrawOnPricePanel = true; Overlay = true; } /// <summary> /// Called on each bar update event (incoming tick) /// </summary> protected override void OnBarUpdate() { if(Close[0] > SMA(20)[0]) // Basic Signal { if(instance == 0) // first instance of our signal { myRay = DrawRay("myRay", 0, Close[0], -1, Close[0], Color.Black); instance = 1; barOfInstance = CurrentBar; } if(instance == 1 && CurrentBar > barOfInstance) // second instance of our signal { myRay = DrawRay("myRay", (CurrentBar - barOfInstance), Close[(CurrentBar - barOfInstance)], 0, Close[0], Color.Black); instance = 0; } } } #region Properties #endregion }
