NR99 means the range of nifty is narrowest compared to past 99 days.
like what we are calling NR7 is the narrowest range in past 7 days including that days range.
it shows the contraction of nifty.
Thanks Rohan for the explaining NR99.
gurprB2J, don't wait for NR99 as they rarely appear. Even NR7 days (narrowest range of last 7 days come hardly 15% of the time). Number bigger then 7 after NR has no extra meaning in interpretation but just that we have seen higher degree of contraction and range expansion is just around the corner.
Don't interpret that if NR7 break, gives 150 points opportunity then NR99 will give atleast x time bigger opportunity. There is no base for such logic (atleast I have not seen any base so far)
