Double Bar Histogram Overlay - not sure how to do this.

[hunter2379]

Basically I want to have a red bar histogram and a green bar histogram so they're overlaid.

Example picture attached. Idea is from: https://github.com/jackiewoodall/tv-...readme-ov-file, which is for Tradovate but want to recreate it on NT.

Any ideas how I would go about doing this? I was looking at the VOL indicator script to see but having trouble getting it to present both bars.

Code that shows nothing:

protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                                    = @"Enter the description for your new custom Indicator here.";
                Name                                        = "BullsvsBears";
                Calculate                                    = Calculate.OnEachTick;
                IsOverlay                                    = false;
                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(new Stroke(Brushes.DodgerBlue, 2),    PlotStyle.Bar,    Custom.Resource.VOLVolume);
                //AddLine(Brushes.DarkGray, 0,            Custom.Resource.NinjaScriptIndicatorZeroLine);
                
                
                AddPlot(new Stroke(Brushes.Green, 2),    PlotStyle.Bar,    "Bulls");
                AddLine(Brushes.DarkGray, 0, "Bulls_" + Custom.Resource.NinjaScriptIndicatorZeroLine);
                
                
                AddPlot(new Stroke(Brushes.Red, 2),    PlotStyle.Bar,    "Bears");
                AddLine(Brushes.DarkGray, 0, "Bears_" + Custom.Resource.NinjaScriptIndicatorZeroLine);              
                
            }
            else if (State == State.Configure)
            {
            }
        }

        protected override void OnBarUpdate()
        {
            //Add your custom indicator logic here.
            //Value[0] = Instrument.MasterInstrument.InstrumentType == InstrumentType.CryptoCurrency ? Core.Globals.ToCryptocurrencyVolume((long)Volume[0]) : Volume[0];
            
            double percent_bulls = ((Close[0] - Low[0]) / (High[0] - Low[0]));
            double percent_bears = (High[0] - Close[0]) / (High[0] - Low[0]);
            
            Value[0] = percent_bulls;    
            Value[1] = percent_bears;           
        }​

Hello hunter2379,

The BuySellVolume indicator included with NinjaTrader does something similar.

The buys is buys + sells so that both plots are visible.

Thank you so much!! Really appreciate it!

One last question, any idea if there's an indicator that shows the current ATR(20) or ATR(20) * 2 or plots them? I'd like to easily use ATR to set a stop loss without calculating ATR(20) each time I open a new position.

Hello hunter2379,

There is the ATR indicator included with NinjaTrader you can call, is this what you are looking for?
You could call this indicator from a custom indicator and multiple the value by 2 and set this to a plot value.


Below is a link to the ATRTrailing indicator which subtracts the ATR to the current price that can be used to set a stop loss.

Yea, I've looked into that. Just didn't see a clean way of adding it into my chart. I guess, if I have an indicator or strategy running, can I detect when an order is filled via the DOM and for that bar display the ATR ranges I want as dots?

Hello hunter2379,

You can go to the indicators window and select the ATR indicator and click add to add this to a chart.
You can call the ATR() indicator from a custom indicator and plot the value on a chart or plot a dot at the price value.

You can use the Addon approach in an indicator to trigger an action like drawing a dot when an order fills on an account by adding an event handler method to the <Account>.ExecutionUpdate event.
