Plot line from X day high from X days ago?

Hey,

Need some help, even more is I would love to learn, how to find a value/condition in the past, and draw a horizontal line from it. I understand how to plot a line from a high bar but haven't figured out how to in relation to time. What I want to do is based off a scan from stockfetcher. Ultimately I want to make a TOS scan from it but it think the study would be useful to visualize.

https://www.stockfetcher.com/sfforums/?mid=149271

The study will find a 10 days high within 10 days and the 20 day high within 60 days and calculates the value if a line connected the two highs to today. The scan would find when price crosses above that calculated value.

So from my little knowledge of coding I have been playing around with...

highest(high[10], 100); and
getvalue to find the point
(Not the full script, just two commands that seem useful)

Am I using these right, how off is this?
My other �tries� have included tweaking the Near_high_low scan from the condition wizard.

def price = close;
input period = 252;
input choice = {default High, Low};
input choice1 = 3;

def hi = high;
def lo = low;

plot scan;
switch (choice) {
case High:
scan = price >= highest(hi,period)* ((100 - choice1) /100);
case Low:
scan = price <= lowest(lo,period)* ((100 + choice1) /100);;

Would appreciate an explanation of how the code should be written. Or a tutorial or other script I could use.

Teach me how to fish.

Hi Ken,

I think the main issue here is the trend line coding if I understand that correctly.

I used TOS and think script in the past, but I found it to be a bit limited. I just looked at the paltform again under thinkscript and I could not find any think that is related to trend line where it could be a start for coding a line. So this would be a big stopper here.

A scan by itself does not do anything with trend lines either.

So unless you can find some where in thinkscript an example of how to draw a line, that would be difficult to do. May be i didn't look deep enough to find it.

There is a programmer out there who did some good things with TOS, and he programs for a fee. He has some free tutorials and Q&A on his site that might point you in the write direction, or give you a clear answer if it is possible or not possible to code that trend line in TOS. His site is : https://www.hahn-tech.com/.

Hope that helps in any way.
