What’s the Downside with Foreign money Correlation?
Whenever you’re constructing a foreign currency trading bot, one large problem usually will get ignored—forex correlation. In case you’re buying and selling a number of pairs directly, not being attentive to how these pairs transfer collectively can result in pointless threat.

EURUSD: BUY
-
GBPUSD: BUY
-
AUDUSD: BUY

-
Excessive correlation (0.8–0.9): Max 2 positions
-
