You are not going to get the same results from calculating the RSI by
hand because you aren't going to have precisely the same pricing data
that any automated program is using. The RSI values from MS won't be
exactly the same as the RSI values from Big Charts.
Here is the formula in algebraic terms. You would have to use exactly
the same numbers in every case as MS is using--which probably is not
possible. The question is how close is close enough.
Average price change on up days
Relative Strength = ---------------------------------
Average price change on down days
The indicator (RSI) is calculated from the RS value as follows:
100
RSI = 100 - ------
1 + RS
RS = P / N
P = PS / n1 N = NS / n2
PS = Total of PCi values NS = Total of NCi values
PCi = positive price change NC = negative price change
for period i for period i
Pp = previous value of P Np = previous value of N
(initially 0) (initially 0)
n1 = number of times the price changed in the positive
direction in the last n periods. There will be n1 PCi
values to add together to get PS.
n2 = number of timee the price changed in the negative
direction in the last n periods. There will be n2 NCi
values to add together to get NS.
n = n1 + n2 (the number of periods in the RSI calculation)
