no High Low of Custom candles in my Delta indicator

[memonolog]

Hello everyone, no High Low of Custom candles in my Delta indicator

Created a Delta indicator, which should display delta bars in a new panel, everything works, bars are there, but there are no values where the candle's delta was high and low.

Help me figure it out, thanks

code

private Brush barColorDown = Brushes.Red;
private Brush barColorUp = Brushes.Lime;
private Brush shadowColor = Brushes.Gray;
private Pen shadowPen = null;
private int shadowWidth = 1;

AddPlot(Brushes.Gray, "HAOpen");
AddPlot(Brushes.Gray, "HAHigh");
AddPlot(Brushes.Gray, "HALow");
AddPlot(Brushes.Gray, "HAClose");

private void MyDelta //
{
double Vol = buys + sells;
double Delta = buys - sells;

if (CurrentBar == 0)
{
HAOpen[0] = Open[0];
HAHigh[0] = High[0];
HALow[0] = Low[0];
HAClose[0] = Close[0];
return;
}

HAClose[0] = Delta;// Calculate the close
HAOpen[0] = 0; // Calculate the open

HAHigh[0] = (Math.Max(Delta, HAOpen[0])); // Calculate the high
HALow[0] = (Math.Min(Delta, HAOpen[0])); // Calculate the low

}

public override void OnCalculateMinMax()
{
base.OnCalculateMinMax();

if (Bars == null || ChartControl == null)
return;

for (int idx = ChartBars.FromIndex; idx <= ChartBars.ToIndex; idx++)
{
double tmpHigh = HAHigh.GetValueAt(idx);
double tmpLow = HALow.GetValueAt(idx);

if (tmpHigh != 0 && tmpHigh > MaxValue)
MaxValue = tmpHigh;
if (tmpLow != 0 && tmpLow < MinValue)
MinValue = tmpLow;
}
}

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{

if (Bars == null || ChartControl == null)
return;

int barPaintWidth = Math.Max(3, 1 + 2 * ((int)ChartControl.BarWidth - 1) + 2 * shadowWidth);

for (int idx = ChartBars.FromIndex; idx <= ChartBars.ToIndex; idx++)
{
if (idx - Displacement < 0 || idx - Displacement >= BarsArray[0].Count || (idx - Displacement < BarsRequiredToPlot))
continue;

double valH = HAHigh.GetValueAt(idx);
double valL = HALow.GetValueAt(idx);
double valC = HAClose.GetValueAt(idx);
double valO = HAOpen.GetValueAt(idx);
int x = chartControl.GetXByBarIndex(ChartBars, idx); //was chartControl.BarsArray[0]
int y1 = chartScale.GetYByValue(valO);
int y2 = chartScale.GetYByValue(valH);
int y3 = chartScale.GetYByValue(valL);
int y4 = chartScale.GetYByValue(valC);

SharpDX.Direct2D1.Brush shadowColordx = shadowColor.ToDxBrush(RenderTarget); // prepare for the color to use
var xy2 = new Vector2(x, y2);
var xy3 = new Vector2(x, y3);
RenderTarget.DrawLine(xy2, xy3, shadowColordx, shadowWidth);

if (y4 == y1)
RenderTarget.DrawLine(new Vector2(x - barPaintWidth / 2, y1), new Vector2(x + barPaintWidth / 2, y1), shadowColordx, shadowWidth);
else
{
if (y4 > y1)
{
SharpDX.Direct2D1.Brush barColorDowndx = barColorDown.ToDxBrush(RenderTarget); // prepare for the color to use
RenderTarget.FillRectangle(new RectangleF(x - barPaintWidth / 2, y1, barPaintWidth, y4 - y1), barColorDowndx);
barColorDowndx.Dispose();
}
else
{
SharpDX.Direct2D1.Brush barColorUpdx = barColorUp.ToDxBrush(RenderTarget); // prepare for the color to use
RenderTarget.FillRectangle(new RectangleF(x - barPaintWidth / 2, y4, barPaintWidth, y1 - y4), barColorUpdx);
barColorUpdx.Dispose();
}
RenderTarget.DrawRectangle(new RectangleF(x - barPaintWidth / 2 + (float)shadowWidth / 2,
Math.Min(y4, y1), barPaintWidth - (float)shadowWidth, Math.Abs(y4 - y1)), shadowColordx, shadowWidth);
}
shadowColordx.Dispose();
}
}

my result now

Hello memonolog,

Unfortunately, plot series do not have an open, high, low, close and do not appear the same as candle sticks for bar data.

This would have to be custom rendered similar to the heiken ashi indicator.

where is plot? I don’t use Plot series

if you read it again and look at my code, you will probably understand that there is a custom bars and it is from the indicator to which you have dropped the link

[memonolog]

if I understand correctly

Here

HAHigh[0] = (Math.Max(Delta, HAOpen[0])); // Calculate the high
HALow[0] = (Math.Min(Delta, HAOpen[0])); // Calculate the low

I need to somehow get the maximum value that was in the delta

I don’t know how to do it

[NinjaTrader_ChelseaB]

Hello memonolog,

To confirm, you are only asking about a single line of code and you are not referring to the series added with AddPlot() shown in your first post?

Use the MAX() method to get the largest value in a series for a period.

the question of how to get the maximum delta value in a bar, not the last value that is displayed by the Delta variable, but the maximum that would be in the bar

double Delta = buys - sells;


HAClose[0] = Delta;// Calculate the close
HAOpen[0] = 0; // Calculate the open

HAHigh[0] = buys; // Calculate the high
HALow[0] = sells; // Calculate the low

how to get it using the the MAX () method?
What's the correct syntax?

Hello memonolog,

I'm sure that I understand. I was previously thinking you want the largest delta value in a series of bars.. but this is not what you want.

The buys - sells is not the maximum delta?

What is the maximum delta that you are looking for?

buys - sells ( Delta)
it turns out that this is the maximum delta when the bar is closed, last delta, final delta in the bar (in my code it is HAClose [0] = Delta; // Calculate the close delta)

but I need to get at the moment the maximum delta that was in the bar, in general - in your indicator (Order Flow Cumulative Delta, delta type BAR 'second picture in my post') this is just a candle wick - which I am trying to implement in my indicator

Hello memonolog,

So you want to process each tick as a bar is built, and if the buys - sells is greater than the value saved to a variable, save the larger value to a variable, is this correct?

private double maxDelta;

if (IsFirstTickOfBar)
maxDelta = 0;

maxDelta = Math.Max(maxDelta, buys - sells);

if (IsFirstTickOfBar)
int maxDelta = 0;

maxDelta = Math.Max(maxDelta, buys - sells);

maxDelta int???

or

double maxDelta = 0;
if (IsFirstTickOfBar)
{
maxDelta = 0;
}
maxDelta = Math.Max(maxDelta, buys - sells);z

Hello memonolog,

double would be correct for decimal values.

[memonolog]

if I did it right, I still get the final bar delta to the maximum location, that is, wick draws me the same value as the Delta variable in my code, compared with your indicator

double maxDelta = 0;
double minDelta = 0;

if (IsFirstTickOfBar)
{
maxDelta = 0;
minDelta = 0;
}

maxDelta = Math.Max(maxDelta, buys - sells);
minDelta = Math.Min(minDelta, buys - sells);


if (CurrentBar == 0)
{
HAOpen[0] = Open[0];
HAHigh[0] = High[0];
HALow[0] = Low[0];
HAClose[0] = Close[0];
return;
}

//HAClose[0] = Delta;// Calculate the close
HAOpen[0] = 0; // Calculate the open
HAHigh[0] = maxDelta; // Calculate the high
HALow[0] = minDelta; // Calculate the low

not working I get the same values as the Delta variable

Hello memonolog,

Are you viewing the prints of each tick update? Which delta calculation had the highest value?

no .., how to do this?
