Daos anybody here who can say me why in the hell this indicator won't work?
U have to problems:
1) the definition of GbpUsd was not an Array.
2) U have zero divizion
Change it to :
double tmp = MathSqrt((sumX2-(MathPow(sumX,2)/R_Period))*(sumY2-(MathPow(sumY,2)/R_Period)));
if (tmp == 0) tmp = Point;
Oh, i see... thank you
however, now i can see its value, the problem is that this value should be between 1 and -1 and with this solution it shows values greater than 1
i have to give a deep look to the Pearson formula...
Thank you again..
maybe, you want to check the Pearson formula.... ... no, eh?
thx. i was looking for it

Practical application of correlations in trading
Correlation is a statistical relationship between two or more random variables (or quantities which can be considered random with some
acceptable degree of accuracy). Changes in one ore more variables lead to systematic changes of other related variables. The
mathematical measure of the correlation of two random variables is the correlation coefficient. If a change in one random
variable does not lead to a regular change in the other random variable but leads to a change in another statistical
characteristic of this random variable, such a relation is not considered correlation, although it is statistical.
