Highest High Lowest Low N bars back

[Ccowl1]

Hi,
Im trying to code a simple indicator that would draw Fib. retracement based on the highest high and lowest low of N bars back. I found one indicator that draws the fib based on the range of a specific time an another one that draws it based on the high and the low of the day. I need N bars back only, very simple.

Im trying to adjust an existing indicator but can't seem to get the highest high and lowest low for the especific 50 bars back

Can you help me here?

Will greatly appreacite any comments.
Thanks.

protectedoverridevoid OnBarUpdate()
{ if(CurrentBar<50) return;

{ if(FirstBar<0) FirstBar=CurrentBar;

if(HighestHigh<0.0)
{ HighestHigh = High[0];
LowestLow = Low[0];
} else
{ if(High[0]>HighestHigh)
{ HighestHigh = High[0];
HighBar=CurrentBar;
if(showHighAndLow) DrawHorizontalLine("High",false,HighestHigh,Color.Gray,DashStyle.Solid,1);
}
if(Low[0]<LowestLow)
{ LowestLow = Low[0];
LowBar=CurrentBar;
if(showHighAndLow) DrawHorizontalLine("Low",false,LowestLow,Color.Gray,DashStyle.Solid,1);
}
}

Hello,

Sure, If it was me I would use the MAX() function.

http://www.ninjatrader-support.com/HelpGuideV6/MaximumMAX.html

And MIN().

This will do exactly what your looking for.

Let me know if I can be of further assistance.

Hi Brett, thanks for getting back to be so fast.

I follow your advice and used the MAX and MIN, and and I was able to get the highest high and lowest low I was looking for.

Now I wanted to get only the current value, and I am getting that for the lowest low but the highest high seems to keep plotting all the previous values. I can't find the error, can you help me?

And also I'm having problems when trying to get the value of the highest high and lowest low to draw the fib. Is there any other sample I may follow?

I really appreciate all your help.

Thank you I have a good day.

protected override void OnBarUpdate()
{
double highestHigh = MAX(High, 100)[0];
double lowestLow = MIN(Low, 100)[0];


if(ShowHigh)
{
if (!PlotCurrentValue || highestHigh != High[0])
HighestHigh.Set(highestHigh);
else
for (int idx = 0; idx < HighestHigh.Count; idx++)
HighestHigh.Set(idx, highestHigh);
}

if (ShowLow)
{
if (!PlotCurrentValue || lowestLow != Low[0])
LowestLow.Set(lowestLow);
else
for (int idx = 0; idx < LowestLow.Count; idx++)
LowestLow.Set(idx, lowestLow);
}

}

Hello,

What do you mean by highest high keeps plotting? Can you please send a screenshot of what your seeing.

To send a screenshot press Alt + PRINT SCREEN to take a screen shot of the selected window. Then go to Start--> Accessories--> Paint, and press CRTL + V to paste the image. Lastly, save as a jpeg file and send the file as an attachment.


Also, I not sure what your refering too for this: value of the highest high and lowest low to draw the fib

Lowest low and highest high of what? The day?

I look forward to assisting you further.

Data Box

Hi,

I have an indicator which values I don't want to see plotted on the chart, but I do want to see them in the data box. I changed the color of the indicator to transparent, but this takes it away from the data box. I know this is supposed to happened in NT7, and I was wondering if there is a way to having the indicator be transparent and still show in the data box.
thanks

Glad to hear,

Also on your secondary question I unfortunately do not know of a way to do this currently.

Let me know if I can be of further assistance.
