Adjusting standard indicator (plotting arrows)

April 24th, 2019, 12:38 AM

I am currently trying to add an indicator to my trading system and i would like it to create some alerts.

The indicator i am currently trying to adjust is CCI_Average.
With the standard code this indicator allows for an audio and visual alert to pop up once the CCI value crosses the overbought or oversold area. I have already managed to adjust the code so now the alert pops up when the CCI value crosses both the overbought or oversold are AND the CCI average at the same time.

What i would like to get done now is that once the alert is triggered, the indicator also draws an up arrow for buy signals and a down arrow for sell signals.

I have found some guidelines online but they all seem to be outdated.
Here is the code i am currently working with:

Code

using System;
using System.Drawing;
using PowerLanguage.Function;

namespace PowerLanguage.Indicator
{
    public class CCI_AverageCUSTOMandARROW : IndicatorObject
    {
        private VariableSeries<Double> m_ccivalue;

        private VariableSeries<Double> m_cciavg;

        private IPlotObject Plot1;

        private IPlotObject Plot2;

        private IPlotObject Plot3;

        private IPlotObject Plot4;

        public CCI_AverageCUSTOMandARROW(object ctx) :
            base(ctx){
            overbought = 100;
            oversold = (-1*100);
            cciavglength = 10;
            ccilength = 11;
        }

        [Input]
        public int ccilength { get; set; }

        [Input]
        public int cciavglength { get; set; }

        [Input]
        public double oversold { get; set; }

        [Input]
        public double overbought { get; set; }

        protected override void Create(){
            m_ccivalue = new VariableSeries<Double>(this);
            m_cciavg = new VariableSeries<Double>(this);
            Plot1 =
                AddPlot(new PlotAttributes("CCI", 0, Color.Cyan,
                                           Color.Empty, 0, 0, true));
            Plot2 =
                AddPlot(new PlotAttributes("CCIAvg", 0, Color.Blue,
                                           Color.Empty, 0, 0, true));
            Plot3 =
                AddPlot(new PlotAttributes("OverBot", 0, Color.Green,
                                           Color.Empty, 0, 0, true));
            Plot4 =
                AddPlot(new PlotAttributes("OverSld", 0, Color.Green,
                                           Color.Empty, 0, 0, true));
        }

        protected override void CalcBar(){
            m_ccivalue.Value = Bars.CCI(ccilength);
            m_cciavg.Value = m_ccivalue.Average(cciavglength);
            Plot1.Set(0, m_ccivalue.Value);
            Plot2.Set(0, m_cciavg.Value);
            Plot3.Set(0, overbought);
            Plot4.Set(0, oversold);
            if (this.CrossesOver(m_ccivalue, m_cciavg)&&(this.CrossesOver(m_ccivalue, oversold))){
                Alerts.Alert("Indicator indicating BUY");
            }
            else{
                if (this.CrossesUnder(m_ccivalue, m_cciavg)&&(this.CrossesUnder(m_ccivalue, overbought))){
                    Alerts.Alert("Indicator indicating SELL");
                }
            }
        }
    }
}

Thanks in advance!

Hi RDK91,

you can utilize arrow objects for that and this should get you going:

Thanks! This really helped me out!
I managed to get it working, the only problem now is that the arrow is plotted over the candle sticks instead of above it for a sell and below it for a buy. Once i got that fixed it will be finishes, thanks again!

RDK91,

you are welcome and I am glad to hear that.
Without seeing the code it's tricky to point you in the right direction, but you can use different plot locations or arrow directions based on the signal. This way one arrow could point up using a green color and be located under a bar, while the other arrow could point down using a red color and a location above the high.

Currently the code is like this:

Code

IArrowObject arrowData1 = DrwArrow.Create(new ChartPoint(Bars.CurrentBar, BarsOfData(1).Close[0]), false);
				arrowData1.Size = 10;

The upward arrows are blue right now and the down arrows are red (not sure yet how i can change this).
I will also attach a screenshot so you can see what i meant by the arrows are plotted over the candles instead of above/below.

My coding experience is 0 so i really appreciate you pointing me in the right direction!

Edit: managed to change the colors!

RDK91,

you are using the Close as location in your code:

Code

new ChartPoint(Bars.CurrentBar, BarsOfData(1).Close[0])

Using the High or Low, depending on the signal should do it.

I wish i could give you more likes! You are my hero!

Everything is exactly as i wanted it now, thank you so much!

RDK91,

you are welcome and thank you for the kind words.

You might want to consider posting the code for the benefit of others in the futures.io community.

You are right, here is the code! This is just the standard CCI_Average code that i have adjusted so i will only post the part that i have adjusted, the rest is just standard, apart from the settings.

Code

protected override void CalcBar(){
            m_ccivalue.Value = Bars.CCI(ccilength);
            m_cciavg.Value = m_ccivalue.Average(cciavglength);
            Plot1.Set(0, m_ccivalue.Value);
            Plot2.Set(0, m_cciavg.Value);
            Plot3.Set(0, overbought);
            Plot4.Set(0, oversold);
            if (this.CrossesOver(m_ccivalue, m_cciavg)&&(this.CrossesOver(m_ccivalue, oversold))){
                Alerts.Alert("Indicator indicating BUY");
				IArrowObject arrowData1 = DrwArrow.Create(new ChartPoint(Bars.CurrentBar, BarsOfData(1).Low[1]), false);
				arrowData1.Size = 5;
				arrowData1.Color = Color.White; 
				
            }
            else{
                if (this.CrossesUnder(m_ccivalue, m_cciavg)&&(this.CrossesUnder(m_ccivalue, overbought))){
                    Alerts.Alert("Indicator indicating SELL");
					IArrowObject arrowData1 = DrwArrow.Create(new ChartPoint(Bars.CurrentBar, BarsOfData(1).High[1]), true);
					arrowData1.Size = 5;
					arrowData1.Color = Color.White;
