How to Use Correlation Calculator for Currency Pairs
Author: Victor Gryazin
Dear Clients and Partners,
This overview is devoted to the issue of correlation of currency pairs, counting it with a special calculator, and using it in trading.
What is currency pair correlation
In finance, correlation is a statistical measurement of how two assets move one against another. In other words, this is the capability of one financial instrument follow another one. For example, gold and silver have high correlation.
The idea of currency correlation represents the connections between currency pairs in Forex, the dependence of their movements one from another. Correlation demonstrates whether two pairs fluctuate similarly: the higher the correlation, the more in run are the two pairs. Currency pairs with strong correlation move somewhat in unison.
Positive correlation
Positive (or direct) correlation means that quotes go in the same direction – up or down.
For example, strong positive correlation is demonstrated by EUR/USD and EUR/CAD. In the picture below it is obvious that the quotes of these pairs often go in one direction, and their charts look quite similar.
How to calculate correlation indices
To assess the correlation of two instruments, there is a special index. It is estimated in shares, or percent: 100% = 1 for positive correlation and -1 for negative.
For calculating the index, Pearson’s formula is used. First, a set of values of both assets is formed – X and Y. Then average X and Y values are calculated. Next, they add up the product of the deviation of each set from the average and divide them by the product of the standard deviation.
The values of the correlation index are between +1 and -1.
The meaning of the values is as follows:
It should be noted that correlation between two currency pairs is not a stable and constant factor. It can change with time. Different political and social crises, unexpected changes in credit and monetary policies can alter the normal correlation at any moment, so that it stops working normally.
So, when using correlation in trading, the trader has to follow their risk management rules. Correlation can be used as some sort of a filter alongside classical fundamental and tech analysis. Before using correlation for real, practicing on a demo account is highly recommended.

The values of the correlation index are between +1 and -1.
The meaning of the values is as follows:
- 0 – no correlation. Currency pairs show no dependence on one the other.
- +1 – full positive correlation. Two currency pairs go in one direction, coinciding in movement size.
- -1 – full negative correlation. Two currency pairs go in the opposite directions, coinciding in movement size.
It should be noted that correlation between two currency pairs is not a stable and constant factor. It can change with time. Different political and social crises, unexpected changes in credit and monetary policies can alter the normal correlation at any moment, so that it stops working normally.
