Currency pair correlations

I have made some research about correlations in the most popular crosses like eur/usd and usd/jpy etc.

In Wikipedia.org you can see the explanation of correlation.

The term correlation can also mean the cross-correlation of two functions or electron correlation in molecular systems.

In probability theory and statistics, correlation, also called correlation coefficient, indicates the strength and direction of a linear relationship between two random variables. In general statistical usage, correlation or co-relation refers to the departure of two variables from independence. In this broad sense there are several coefficients, measuring the degree of correlation, adapted to the nature of data.

The correlation is based on 527 cases of 4H periods (large statistical probe).
The cases marked in red are statistically important. If the cross is more closer to 1 it is more correlated.
