Supports six pairs across USD, EUR, GBP and JPY. Enter up to eight held positions and one separate proposed trade for comparison.
Supported pairs: USD/JPY · EUR/USD · GBP/USD · EUR/JPY · GBP/JPY · EUR/GBP
Compare two held positions and one proposed trade by currency
Fixed rates for this explanation: EUR/USD = 1.10, USD/JPY = 150 and GBP/USD = 1.25. These assumptions provide reference values for USD, EUR, GBP and JPY. They are neither current ECB rates nor rates you can enter in the tool. The live screen uses ECB reference values for the displayed reference date, so its results may differ.
Quantity is in the currency on the left of the pair, the base currency. Consider holding a buy of 10,000 USD in USD/JPY and a buy of 10,000 EUR in EUR/USD. The proposed trade for comparison is a buy of 1,000 USD in USD/JPY.
| Currency | Two held positions | With proposed trade |
|---|---|---|
| USD | -1,000 | 0 |
| EUR | +11,000 | +11,000 |
| JPY | -10,000 | -11,000 |
| GBP | 0 | 0 |
The held USD exposure is +10,000 − 11,000 = −1,000 USD. The proposed buy adds +1,000 USD and −1,000 USD equivalent of JPY, bringing net USD to zero. The net EUR purchase and net JPY sale remain.
Offsetting USD does not make risk or required margin zero. This is not an assessment including fees, spreads, interest or margin, and it is not a trading recommendation. The proposed trade is for comparison and is not saved. Only held positions you choose to save are stored in this browser on this device.
If the live values differ, check the reference date, buy or sell direction, and currency-unit or lot setting. If rates fail to load, do not use an assumed result; recalculate after reference values become available.
Match your quantity units
Choose units or lots, then set 1,000, 10,000 or 100,000 units per lot. Check the contract size against your own account; the app cannot detect your broker’s settings.
Enter held positions
Choose a pair, direction and quantity. Fractional currency units are rejected. Currency balances are USD equivalents, not margin requirements.
Compare a proposed trade
Review added, reduced, offset or reversed balances. A net balance of zero does not remove fees, margin needs or other risks.
Check dates and decide whether to save
Read the reference date. Saving requires an explicit action and stays in this browser. Another person using the same browser may be able to read saved positions.
