Draw Line

[EthanHunt]

I am trying to draw a line using the following formula (Midpoint). It should start at the beginning of the session and run to current adjusting along the way. I looked at Draw.Line but am getting errors. Any help would be appreciated. Thank you.

CurrentDayOHLC().CurrentLow[0] + (CurrentDayOHLC().CurrentHigh[0] - CurrentDayOHLC().CurrentLow[0])

Hello EthanHunt,

Thank you for your post.

I would suggest assigning that calculation to a Plot:

Here's a quick example:

        private CurrentDayOHL CurrentDayOHL1;
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                                    = @"Enter the description for your new custom Indicator here.";
                Name                                        = "AddAPlot";
                Calculate                                    = Calculate.OnBarClose;
                IsOverlay                                    = true;
                DisplayInDataBox                            = true;
                DrawOnPricePanel                            = true;
                DrawHorizontalGridLines                        = true;
                DrawVerticalGridLines                        = true;
                PaintPriceMarkers                            = true;
                ScaleJustification                            = NinjaTrader.Gui.Chart.ScaleJustification.Right;
                //Disable this property if your indicator requires custom values that cumulate with each new market data event. 
                //See Help Guide for additional information.
                IsSuspendedWhileInactive                    = true;
                AddPlot(Brushes.Orange, "MyPlot");
            }
            else if (State == State.DataLoaded)
            {
                CurrentDayOHL1 = CurrentDayOHL();
            }
        }

        protected override void OnBarUpdate()
        {
            Value[0] = CurrentDayOHL1.CurrentLow[0] + (CurrentDayOHL1.CurrentHigh[0] - CurrentDayOHL1.CurrentLow[0]);
        }

        #region Properties

        [Browsable(false)]
        [XmlIgnore]
        public Series<double> MyPlot
        {
            get { return Values[0]; }
        }
        #endregion

This will plot this as a line all the way to the current bar, changing as the calculation changes.

Please let us know if we may be of further assistance to you.

Thanks. This appears to be plotting a line at the high of the day only. The calcs look right though...

Hello EthanHunt,

Thank you for your reply.

That would be because I used your calculation, which simply subtracts the low from the high and then adds it again to the high, leaving you with a value equal to the high. You can absolutely adjust the calculation however you like.

Please let us know if we may be of further assistance to you.

You're correct, I fixed it. Thanks
