Remarks

The concept of Directional Movement is based on the assumption that in an upward trend today?s highest price is higher than yesterday?s highest price and in a downward trend today?s lowest price is lower than yesterday?s lowest price. If this is the case, it is a matter of the so-called Outside Days.

The Directional Movement Index (DX) is calculated by dividing the difference between the PDI and MDI by the sum of both figures. The result is a percentage, with which the extent and/or intensity or the trend is quantified.

Note, that there are two styles of indicator ADX. Some trading systems use a bit diffrent formula to calculate this indicator. Therefore Quant Studio gives an opportunity to use two styles ADX - classical (QuantStudio style) and little bit changed (MetaStock style.)

ADX has QuantStudio style by Default.

Formula for Quant Studio (classical) style:

TDataManager.cd("demo");

TInstrument Instrument = TDataManager.GetInstrument("YHOO");

DateTime Date1 = DateTime.Parse("2000/01/04"); 
DateTime Date2 = DateTime.Parse("2000/12/29"); 

TDailyArray Array = Instrument.DailyArray.Clone(Date1, Date2);

TCanvas Canvas = new TCanvas("Canvas", 600, 800);

Canvas.Divide(1, 4);

Canvas.cd(1);

Array.Draw("C");
Array.SMA(14).Draw("S", Color.Red);

Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRangeX(Date1, Date2);

Canvas.cd(2);

Array.DX (14).Draw(Color.Violet);
Array.PDI(14).Draw(Color.Red);
Array.MDI(14).Draw(Color.Blue);

Canvas.Pad.Title.Text = "+/- DI, DX";
Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRange(Date1, Date2, 0, 100);

Canvas.cd(3);

Array.ADX (14).Draw(Color.Red);
Array.ADXR(14).Draw(Color.Blue);

Canvas.Pad.Title.Text = "ADX, ADXR";
Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRangeX(Date1, Date2);

Canvas.cd(4);

Array.PDM().Draw(Color.Purple);
Array.MDM().Draw(Color.Green);

Canvas.Pad.Title.Text = "+/- DM";
Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRangeX(Date1, Date2);

Formula for MetaStock style is the same as for QuantSudio style, but calculation of DX uses PDI and MDI indicators, which formulas each has two styles.

TDataManager.cd("demo");

TInstrument Instrument = TDataManager.GetInstrument("YHOO");

DateTime Date1 = DateTime.Parse("2000/01/04"); 
DateTime Date2 = DateTime.Parse("2000/12/29"); 

TDailyArray Array = Instrument.DailyArray.Clone(Date1, Date2);

EIndicatorStyle Style = EIndicatorStyle.MetaStock;

TCanvas Canvas = new TCanvas("Canvas", 600, 800);

Canvas.Divide(1, 4);

Canvas.cd(1);

Array.Draw("C");
Array.SMA(14).Draw("S", Color.Red);

Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRangeX(Date1, Date2);

Canvas.cd(2);

Array.DX (14, Style).Draw(Color.Violet);
Array.PDI(14, Style).Draw(Color.Red);
Array.MDI(14, Style).Draw(Color.Blue);

Canvas.Pad.Title.Text = "+/- DI, DX";
Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRange(Date1, Date2, 0, 100);

Canvas.cd(3);

Array.ADX (14, Style).Draw(Color.Red);
Array.ADXR(14, Style).Draw(Color.Blue);

Canvas.Pad.Title.Text = "ADX, ADXR";
Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRangeX(Date1, Date2);

Canvas.cd(4);

Array.PDM().Draw(Color.Purple);
Array.MDM().Draw(Color.Green);

Canvas.Pad.Title.Text = "+/- DM";
Canvas.Pad.LegendEnabled = true;
Canvas.Pad.SetRangeX(Date1, Date2);
