Correlation: Correlation measures how closely two markets move together, from +1 (in step) to −1 (opposite).

Correlation in forex

Many pairs share a currency, so they move together. EUR/USD and GBP/USD often rise and fall together because both are priced in dollars, while EUR/USD and USD/CHF often move in opposite directions. Correlations change over time, especially around central bank surprises, so measure them on recent data rather than relying on fixed tables.

Why it matters for risk

Two positions on highly correlated pairs are close to one larger position. Buying EUR/USD and GBP/USD with 1% risk each can behave like a 2% dollar short. The correlation calculator lets you paste two price series and measure the correlation of their returns.

Worked example

If EUR/USD and GBP/USD show a correlation of +0.85 on daily returns over three months, a long on both is mostly a bet against the dollar, not two separate ideas.

Common mistakes

  • Correlating price levels instead of returns.
  • Treating correlation as permanent.

If you follow trade signals, for example the gold signals or EUR/USD signals, understanding this term helps you size and manage each trade yourself. The free Forexuro Telegram channel shares daily market updates where these ideas are used in practice.
