Correlated positions: EURUSD and GBPUSD at the same time

[FXS London Scalper]

Opening EURUSD and GBPUSD in the same direction at the same time often feels like two trades. It's closer to one larger dollar trade.

Why: both pairs share the dollar leg, and on most days they move together. A dollar move hits both.

What this means for risk:

• Two 1% trades in the same direction can behave like a 1.5% to 2% trade on dollar days.
• A news surprise in the US stops both at once, often with slippage.

Ways to handle it:

• Count exposure per currency. Long EURUSD and long GBPUSD is short dollar twice.
• Allow only one dollar trade at a time, or halve the size when two are open.
• Prefer the pair with the cleaner setup, rather than taking both.

When two pairs can make sense: when the story is about one currency, for example euro strength against both dollar and sterling.

Whatever method you choose, write it into the plan as a number, so it's applied the same way on every trade.

I used to take both pairs on the same signal and felt very diversified until a US data release stopped me out on both within about forty seconds. Together it was a larger loss than I had planned for either, and the slippage on the second one was worse than on the first. That day got me to change how I look at risk.

Now I add up exposure by currency before I enter. If I am already long EURUSD and a GBPUSD setup appears, I only take it if the EUR trade has already moved to breakeven, and then at half size. Otherwise I leave it alone and wait for the first trade to resolve.

An exception I allow is a cross like EURGBP, where the two legs largely cancel the dollar. I have taken that with an open EURUSD trade a few times, and the correlation was weak enough that it behaved like a separate position.
