Converting Coordinates to NT8

[aligator]

Dear Support,

globalLine coordinates from an NT7 indicator for a user dawn line are:

						leftY 			= globalLine.EndY;
						rightY			= globalLine.StartY;
						leftBarsAgo		= globalLine.EndBarsAgo;
						rightBarsAgo	        = globalLine.StartBarsAgo;

converted to NT8

						leftY 			= globalLine.EndAnchor.Price;
						rightY			= globalLine.StartAnchor.Price;
						leftBarsAgo		= globalLine.EndAnchor.BarsAgo;
						rightBarsAgo	        = globalLine.StartAnchor.BarsAgo;

compiles but does not seem to plot. Are these definitions for left and right correct for NT8? Am I supposed to use SlotIndex instead (i.e.globalLine.EndAnchor.SlotIndex)?

Thanks

Hello aligator,

Thank you for your note.

So I can best answer your question, would you please provide some context of what you are attempting to convert or where these code blocks are coming from? Perhaps the name of the indicator or section of the helpguide you are referencing?

I look forward to your reply.

Thanks Alan,

This is an indicator conversion of Y and X (start and end) coordinates for a user draw line (globalLine) in NT7 to NT8.

In the post #1- Is the second script block the proper code in NT8 for the start and end of a line or I need to use SlotIndex instead of BarsAgo for the X coordinate or is it something else?

(ref: DrawObjects - Looping through the collection to find specific draw objects)

Many thanks.

Hello alligator,

If you add prints to the script for what you’re attempting to set leftY to, are you seeing an output?

Do you have a sample script which demonstrates what you’re trying to do?

I look forward to your reply.

Thnaks Alan,

Here is the converted file. It works fine now, but on and off. I have commented out areas that I have converted to NT8. See lines 115 to 144 in regards to proper conversion of a user drawn line coordinates as shown in post #1.

I am planning to post and share this conversion when I have cleaned it up and possibly added a couple of features including features for market analyzer.

Many thanks.

Hello aligator,

I apply the indicator to a chart, draw a Line on the chart, the line changes colors and an alert sound is played when the price crosses the line.

In your first post you mention it doesn't plot, is it supposed to plot? What is the issue I'm looking for exactly here, the indicator appears to work fine.

I look forward to your reply.

Thanks Alan,

No plot, what I meant was no Alert. Initially I converted horizontal coordinate to Start/EndAnchor.BarsAgo then I changed it to Start/EndAnchor.SlotIndex and it seems to work now, but not all the time for all line types.

But, I am not sure if the coordinates conversion is correct or not since the indicator does not seem to work all the time for all four types of line. Did you draw Line, Ray, Extended Line, and Horizontal Line and alert worked for all of them? In my case, the line changes color to red but no alerts are generated.

Thanks.

Hello alligator,

I used a ray.

That the indicator works correctly at least one time hints that the coordinates are correct, as do prints when I add them to the script. How the indicator handles additional drawing lines, resetting of the alarm, where the start and end anchor are in relation to each other could be the issue.

Does the indicator stop working when you add additional lines to the chart?

If you only apply one chart, does the indicator always work as expected?

I look forward to your reply.

I only use one chart (1m) and one user drawn line (any type) with the start in the past and end in future, and rearm resets on new bar.

Receiving no alarms when crossing now and get the No alert message. I did get some alarms before after crossing but not always.

Thanks.

Hello aligator,

I would suggest adding print statements to check whether and when your conditions are becoming true. I’ve provided a link to a youtube video which covers an example of using prints to understand behavior: https://www.youtube.com/watch?v=K8v_...tu.be&t=48m45s

I’ve provided a link covering debugging which you may find helpful.
