Fractal Trendline For ThinkOrSwim

Men of courage and of valor! I need some help with coding this code into ToS. The correct syntax needed is escaping me. I would like the desired ToS code to be based on this code....

Trend = (((average(highest price in past 90 periods, lowest price in past 90 periods))*8)+((average(highest price in past 120 periods, lowest price in past 120 periods))*4)+((average(highest price in past 180 periods, lowest price in past 180 periods))*2))/14

Thanks Much!
 
Solution
@Riff I think I have this right -
Code:
#Trend = (((average(highest price in past 90 periods, lowest price in past 90 periods))*8)
#+((average(highest price in past 120 periods, lowest price in past 120 periods))*4)
#+((average(highest price in past 180 periods, lowest price in past 180 periods))*2))/14

def h = high;
def l = low;
def a1 = (highest(h, 90) + lowest(l, 90)) / 2;
def a2 = (highest(h, 120) + lowest(l, 120)) / 2;
def a3 = (highest(h, 180) + lowest(l, 180)) / 2;

plot trend = ((a1 * 8) + (a2 * 4) + (a3 * 2)) / 14;

Because I had the courage and valor to tackle that, I'm asking since you are a man of honor - how did you think of it? This actually looks really good for finding trend.

I believe it’s a weighted average of different length of donchian channel middle lines.
Here it is as a donchian channel

Code:
#Trend = (((average(highest price in past 90 periods, lowest price in past 90 periods))*8)
#+((average(highest price in past 120 periods, lowest price in past 120 periods))*4)
#+((average(highest price in past 180 periods, lowest price in past 180 periods))*2))/14

def h = high;
def l = low;
def a1 = (highest(h, 90) + lowest(l, 90)) / 2;
def a2 = (highest(h, 120) + lowest(l, 120)) / 2;
def a3 = (highest(h, 180) + lowest(l, 180)) / 2;


plot upper = ((highest(h, 90) * 8) + (highest(h, 120) * 4) + (highest(h, 180) * 2)) / 14;
plot middle = ((a1 * 8) + (a2 * 4) + (a3 * 2)) / 14;
plot lower = ((lowest(l, 90) * 8) + (lowest(l, 120) * 4) + (lowest(l, 180) * 2)) / 14;

Ok Pensar, I tried your code and it drew a Cyan line right on top of the line my code drew!!!! So success to both of us! Thanks Much for your time and effort, I appreciate it.

(It seems we are both brilliant coders :))
 
barbaros, the Donchain Channel thing is interesting, middle line seems to be the same as Pensar's code but now I have a channel above and below it. Thanks. I will leave it on my charts and see how much value I derive from having the extra lines above and below.

BTW guys the original code is for a "fractal" trend line.....(for use on day chart). Thanks again to both of you!
