First all seeking thread owner permission to post here...
I am following similar set up,
NR4 is Narrowest Range of last 4 bars.
NR7 is for Narrowest Range of last 7 bars.
i am following NR 21 which means Narrowest Range of las 21 days.
All stocks which comes in NR7 will also come in NR4 and similarly stocks falling under NR 21 will also come in NR7 and NR4 , so basically its just filtration of Narrow range stocks.
** if PH / PL is almost equal to yesterday high / low then i take trade on either above MAX(today's high , yesterday high) or below Min(today's low, yesterday low).
Today's high volume stocks having NR21
Bank Baroda : Today's high = 662 , Today's Low = 651.4 , yesterday low = 651 .
So trade = buy above 662 and sell below 651.
Bata India : Today's high = 720, yesterday's high = 722. today's low 711.85 , yesterday's low 711.3
so trade = buy above 722 and sell below 711.3.
If thread starter believe that i should not have post this thing here then just give hint , i will delete my post
