Exploring TrendChannel values per each parallel line

[shlosh7]

Hi
I'm trying to get the current value of each line.
It seems that I use wrong values for the GetPrice method.
What should I use as StartPrice, TotalPriceRangs, and IsInverted?

The relevant part of my script is below, but results in wrong values:

myTrendChannel = Draw.TrendChannel(this, "MyTrendChannelDown", false, StartBarsAgoD, High[StartBarsAgoD], EndBarsAgoD, High[EndBarsAgoD], MinSwingD, Low[MinSwingD] );

ClearOutputWindow();

foreach (PriceLevel priceLevel in myTrendChannel.PriceLevels)
{
//priceLevel.Stroke = new Stroke(Brushes.Transparent);
double totalPriceRange = myTrendChannel.TrendEndAnchor.Price - myTrendChannel.TrendStartAnchor.Price;
double price = priceLevel.GetPrice( myTrendChannel.TrendEndAnchor.Price, totalPriceRange, false);
Print(price);
Print (priceLevel.Value);
}

Hello shlosh7,

Thank you for your post.

I am looking into this on my end and I will follow up when I have further details.

Hello shlosh7,

(edit)
So I went about this without looking into the GetPrice() method...
The code I have works, but, GetPrice() should be doing the job on its own and I'll look into this.

(2nd edit)
I've also had to modify my custom calculation.

My original statement is below:

The price levels would need to be calculated with logic similar to how these are calculated in the TrendChannel code.

foreach (DrawingTool tool in DrawObjects)
{
	if (tool is TrendChannel)
	{
		TrendChannel channel = tool as TrendChannel;
												
		foreach (PriceLevel priceLevel in channel.PriceLevels)
		{
			// skip the first two price levels which are the start and end prices
			if (channel.PriceLevels.IndexOf(priceLevel) < 2)
				continue;

			double price = Math.Abs(channel.TrendStartAnchor.Price - channel.ParallelStartAnchor.Price) * (priceLevel.Value / 100);

			price = (channel.ParallelStartAnchor.Price < channel.TrendStartAnchor.Price) ? channel.TrendStartAnchor.Price - calculatedPrice : channel.TrendStartAnchor.Price + calculatedPrice;

			Print(string.Format("Level {0}: {1}", priceLevel.Value, price ));
		}						
	}
}

Hi shlosh7,

I think I've got it.

priceLevel.GetPrice(channel.ParallelStartAnchor.Price, (channel.TrendStartAnchor.Price - channel.ParallelStartAnchor.Price), (channel.TrendStartAnchor.Price > channel.ParallelStartAnchor.Price));

The psuedo code would be:
GetPrice(endPrice, range, isNotInverted)

Thanks ChelseaB
Thanks !
I made small update in your code order to make it working, as calculatedPrice was not declared, so the updated two lines looks like this:
double calculatedPrice = Math.Abs(channel.TrendStartAnchor.Price - channel.ParallelStartAnchor.Price) * (priceLevel.Value / 100);

double price = (channel.ParallelStartAnchor.Price < channel.TrendStartAnchor.Price) ? channel.TrendStartAnchor.Price - calculatedPrice : channel.TrendStartAnchor.Price + calculatedPrice;

Hopefully that is the logic you meant to implement.
It works,But, the output prints the Y coordination of each parallel line START , vs. its current value, at last bar update.[0] .
My goal is to detect current price crossing any of the parallel lines, so I have to have their CURRENT values.
What changes should be made?
Thanks again
Will look at your other solution (getprice) now

Hi shlosh7,

I think I've got it.

priceLevel.GetPrice(channel.ParallelStartAnchor.Pr ice, (channel.TrendStartAnchor.Price - channel.ParallelStartAnchor.Price), (channel.TrendStartAnchor.Price > channel.ParallelStartAnchor.Price));

The psuedo code would be:
GetPrice(endPrice, range, isNotInverted)

Hi
Thanks for your reply.
If I got it right, this option will also print the STARTING point of each parallel line.
How do I get the their CURRENT value?
(If possible, please send me your tested code)
Best,

Hello shlosh7,

For the end points, use the channel.ParallelEndAnchor.Price in place of the channel.ParallelStartAnchor.Price and channel.TrendEndAnchor.Price in place of channel.TrendStartAnchor.Price.

Hi Guys,

I am working with the Channel tool and do not see the ParallelEndAnchor as an item in the object. I do see it in the help file, and am using version 8.0.13.1

Please advise.

Thanks

Hello mrlogik,

I am able to reproduce this behavior and I have reported this to our development.

Once I have a tracking ID for this behavior I will post in this thread.

[mrlogik]

Great thank you

[shlosh7]

will it provide the Parralel Lines CURRENT values?

Hi NT,

In the meantime I believe a work around is to access the Anchors collection of the channel object. Of course I have to do a little simple math (compute slope and y intercept) in order to determine the intersect price, but that's not a problem.

[mrlogik]

Hi again,

I went a bit further into this and am finding that the BarsAgo value for the anchors collection is undefined.

Simple block of code to replicate

			foreach (var obj in ChartControl.ChartObjects)
			{		
				if(obj.Name ==  "Trend channel") 
				{
					TrendChannel channel = (TrendChannel)obj;
				
					// Left most point
					double p0 = channel.Anchors.ElementAt(0).Price;					
					// Right most point.
					double p1 = channel.Anchors.ElementAt(1).Price;				
					
					int numBars0 = (int)channel.Anchors.ElementAt(0).BarsAgo;
					int numBars1 = (int)channel.Anchors.ElementAt(1).BarsAgo;
					
					double slope0 = Math.Abs(p0 - p1) / Math.Abs(numBars0 - numBars1);
					
					Print("numBars0 = " + numBars0.ToString());
					Print("numBars1 = " + numBars1.ToString());		

                          }
                 }

My print gives

numBars0 = -2147483648
numBars1 = -2147483648

Please advise.

Hi guys,

Any thoughts / movement on this?

Hello mrlogik,

Thank you for your patience.

I would not have an update at this time but this item is being looked into for the Trend Channel.
