Hi Miska, sorry, I'm only an options and equities trader. There are more FX traders on Zorro so you might want to post your question in a different section.

And yes the Zorro IB plugin works fine, but a bit slow. The extreme slowness I experienced over Christmas was no longer there.. probably IB server maintenance. However, option greeks are not available via fast mode SET_PRICETYPE=8. So, scanning greeks across multiple assets and multiple options chains proved to be too slow for real world trading. I'm looking fat aster alternatives. The problem is not every data source is perfect or affordable :-)
