Correlation: Why Two Trades Can Be One | Borearis
Correlation measures how two markets move together. Correlated positions double risk without doubling the edge.
Examples
EUR/USD and GBP/USD often move together; gold and the dollar often move opposite; BTC and ETH are highly correlated.
Rule
Count correlated positions as one risk unit and size accordingly with the position size calculator.

會，危機時常一起下跌。
