Z12 with IB (IBCE)

FX pairs return the following message:
Code
!Order rejected - reason:FX trade would expose account to currency leverage. GBP-CASH--0.00--IDEALPRO/--USD

Indeces and Metals are ok.

Limitation comes from a specific regulation for IB Central Europe only.

I tried:
  • Creating a positive/negative GBP ballance in account by buying manually a GBP/USD CASH
  • changing assets file to use GBP-CFD-SMART-USD
  • any combination of the above with other pairs (including reverse pairs like USD/JPY)


Does anyone trade Z system (FX pairs) in IBCE?
Does anyone use CFD instead of CASH assets with IB?

Thanks
Anton
