The idea behind this method is to find out what would be actual level of nifty on any given day irrespective of how much high or low it has moved.
Studying the historical values of nifty, it has been observed that, nifty moves on an average approx 11 to 12 points (up or down) in a day. Taking this as a bench mark, we tried to find out the actual value of nifty on any given day basis the time period you want to calculate the level.
Method :
Suppose one want to know the actual level of nifty in the last 10 days duration, we find the maximum value of nifty in that last 10 days period and also find the minimum value of nifty in those 10 days.
Calculate the number of days “D1” between that high (max value of 10days) and the current day.
Similarly we calculate the number of days “D2” between the low (min value of those 10 days) and the current day.
Calculate the actual value of nifty as follows :
N1 = Max nifty - (D1 x 12)
N2 = Min nifty + (D2 x 12)
Actual level of nifty on the current day = (N1 +N2)/2
Studying historical data of nifty, we observe that NIFTY takes on an average approximately 92 trading days to scale 1000 points in UP move. Similarly it takes approximately 74 trading days to scale DOWN 1000 points.
This means that on average the movement of nifty per day is 12 points (approx).
The recent high of nifty on 28/10/11 was 5399
on 23rd nov 2011, nifty made a low of 4640.
Suppose we assume that, 4640 is the low and nifty is moving upwards with 12points a day, then the current level of nifty should be
4640 + 12x5 = 4640+60 = 4700
Similary, if we assume that 5399 is the high and nifty is moving downwards at 12 points a day then, the current level of nifty should be
5399 - 12x 20 = 5399 - 240 = 5159
therefore, the exact level of nifty should be = (5159+4700)/2
= 4929.50
Conclusion :
What we try to do here is, from the high point of those 10 days, if nifty move down as per the average (12 points) every day it should reach a particular level. Similarly if nifty move up from the lowest points of those 10 days at a speed of 12 points in a day, it will reach at some level. We calculate the average of these two levels, which should be the actual level of nifty at any given point of time.
