Trend Line Jump

[cbart_1]

I there anyway to get the value of a trend line at the current bar.

AddTrendLine(upTrendStartBarsAgo, startBarPrice, upTrendEndBarsAgo, endBarPrice, UpTrendColor);

this is the code i used to make the trend line.

Hello cbart_1,

Yes, it may be possible with custom programming. Is AddTrendLine() a custom method or an indicator script of yours that draws lines?

One approach to this is to work with exposed ILine values to calculate a slope. Once you have that, can calculate the lines value at any point.

the slope

i know how to figure the slope but how do i use it to figure the value of the current bar.

OK i loaded up the indicator but there is a lot of extra stuff in in that needs to be taken out.

I created a script that can do this, available here:

Hopefully that provides some guidance on accessing lineValueAtLastBar. This script was created in my spare time. I'm sure you can understand that NinjaTrader is not able to provide additional coding guidance on this project. Should you need this, any of our NinjaScript consultants can assist:

ok I think i got it

thank you for the script you gave but i think i got it i have th ecode to do this but it was for 1 bar over and i want 3 bars over before it alarms.

ok i still have a problem

this is my code to check the previous bars to see if they crossed the trend line. i think i have it correct, but it keeps sounding the alarm on every bar. and it doesnt draw the arrow. so i dont think it is even entering the if statement.

if (Close[3] > DendBarPrice + (Math.Abs(downTrendEndBarsAgo - 3) * DchangePerBar) && Open[2] > DendBarPrice + (Math.Abs(downTrendEndBarsAgo - 2) * DchangePerBar) && Open[1] > DendBarPrice + (Math.Abs(downTrendEndBarsAgo - 1) * DchangePerBar) && Open[0] > DendBarPrice + (Math.Abs(downTrendEndBarsAgo) * DchangePerBar))
{
if(!Historical && sTime[0] == 1)
{
//RemoveDrawObject("DownTrendBreak");
DrawArrowUp("DownTrendBreak", 3, Low[3] + TickSize, Color.Blue);
vPlayCount = 3;
Alert("Alert", Priority.High, "Down trend line broken", iAlert, 100000, Color.Black, Color.Green);
}
}

Best of luck tracking this down, cbart_1. You will need to Print all values to verify they're what you expect, and simplify the code until it's at a point where you can follow the behavior.
