How to use the Currency Correlation Calculator

  1. Paste numeric returns for the first pair or symbol.
  2. Paste the same number of returns for the second pair or symbol.
  3. Use commas, spaces, or line breaks between values.
  4. Read the r value and relationship label.
  5. Compare the output before stacking multiple trades.

Formula

r = covariance(series A, series B) / (standard deviation A x standard deviation B) r ranges from -1.00 to +1.00 R squared = r x r

Example

If two pairs produce r = +0.90 over your sample, they moved very similarly. Taking both may double up on the same market theme.

What to watch

  • Correlation changes across regimes and timeframes.
  • Use returns, not raw prices, for cleaner comparison.
  • A negative correlation can still break during volatile news events.

Frequently asked questions

What does +1 correlation mean?+
It means the two series moved perfectly together in the sample. Real market samples rarely stay perfect.
What does -1 correlation mean?+
It means the two series moved perfectly opposite in the sample.
How many data points should I use?+
More points usually give a steadier estimate, but the sample should match the timeframe you trade.
