Hi Roland,

following up on Niall’s comments, please have a look at Example_8. It covers pricing and exposure simulation for a cross currency swap, so the set up we have chosen there takes cross currency basis into account, and it is assuming EUR collateral.

In Examples/Example_8/Input/ore.xml we say that we want to use the market configuration “collateral_eur”.

In Examples/Input/todaysmarket.xml you then see that this means we use the following discount curves

Yield/EUR/EUR1D
Yield/USD/USD-IN-EUR
Yield/GBP/GBP-IN-EUR
Yield/CHF/CHF6M
Yield/JPY/JPY6M

i.e. Eonia discounting in EUR and e.g. a USD-IN-EUR for discounting USD cash flows.

And finally in Examples/Input/curveconfig.xml you will find the following which defines how the USD-IN-EUR curve is constructed from FX Forwards and Cross Currency Basis Swaps:

USD-IN-EUR
USD collateralized in EUR discount curve
USD



FX Forward

FXFWD/RATE/EUR/USD/3M
FXFWD/RATE/EUR/USD/6M
