Hi all, i am trying to scan with above requirement but i guess my script is wrong.

i am trying to find the last 21 days highest high compare to the last 50 days highest high.

if the last 21 days highest point is higher than the last 50 days highest point, program will return true and look for stock of such condition. Below is my script. may someone help.

def highest21days = highest(high[1], 21);

def highest50days = highest(high[1], 50);

def higherhigh = if highest21days > highest50days then 1 else 0;

plot scan = higherhigh;

Solution
I think "Q' mean that
- if you have a high (let's say 100) in last 21 days
- when you trying to get the high in 50 days, the high(100) in last 21 days data set is also included in last 50 days data set
- therefore, you will only get 50 days high > 21 days high, or, 50 days high = 21 days high
The last 50 contains the last 21 therefore the last 21 will never be higher. Equal Maybe.
Perhaps you would would like to know if the last 50 is higher?

Try using 2 Donchian channels, one set to 21 and the other set to 50, on the daily timeframe. This might give you what you want.
