Measure combined currency exposure
Three open trades can still be one large bet on the dollar. Look through the pair names to the shared exposure.
Look through pair names to find shared risks across open positions.
Different symbols do not necessarily create independent positions. Buying EUR/USD and GBP/USD both sells dollars against another currency. If dollar strength is the main driver, both positions can move against you together even though their charts look different.
Correlation describes how returns moved together over a chosen sample. It changes with period, timeframe and market conditions. Historical correlation is a useful observation, not a permanent hedge ratio or a promise about the next stress event.
Review the direction and size of each underlying currency exposure, then consider combined loss under a shared scenario. Add planned cash risk across positions and allow for simultaneous slippage. Opposite positions may reduce one exposure while leaving others, costs and broker margin requirements. Count risk, not merely tickets on a screen.
Let’s use numbers · hypothetical example
Two demo trades each plan USD 10 loss: long EUR/USD and long GBP/USD. A sudden dollar rally triggers both. The combined planned loss is USD 20, and gaps could make the realised loss larger.
Keep in mind
Several small trades can concentrate risk as much as one large trade. A different symbol is not automatic diversification.
Your turn
List the currency bought and sold in EUR/USD long, GBP/USD long and USD/JPY long. Mark the common dollar directions.
A quick check before we move on
Why might two long EUR/USD and GBP/USD trades lose together?
- All currencies always move identically
- Both can be hurt by broad US dollar strength
- Their pair names contain the same number of letters
Check answer
Both can be hurt by broad US dollar strength Both positions are short dollars in their pair structure. Other factors still influence the final outcomes.
