CFD Leverage in API

hi, does anyone has an example how to define CFD with leverage in any language ? (using TWS API)

 

https://interactivebrokers.github.io/tws-api/basic_contracts.html#cfd

 

hi, thank you. this is working for me, however i am not sure which one of the parameters is the leverage or how do i specify the leverage. Maybe i am missing something obvious here...
My contract definition
sectype="CFD"
contract=Contract()
contract.symbol=symbol
contract.secType=sectype
contract.currency=currency
contract.exchange=exchange
contract.multiplier=???

 

There is no multiplier with CFDs, it's always 1:1. CFDs are like buying stocks/index on margin (you don't own the asset - futures analogy) without expiration and rollover, and you always trade against broker as market maker.
