I'm attaching here the Assets.dta file that I've tweaked for US-based IBFX mini* accounts. I carried the precision to 2 more decimal places in both the PIPCost and Margin columns, based on information from the actual broker (via Download.c script)

I believe this has improved my testing accuracy slightly. If you agree this is all setup correctly, feel free to include it with a future Zorro release to help other US-based IBFX traders.

*NOTE: IBFX only offers "Standard" and "Mini" accounts. The account called "mini" is actually a micro account, allowing nano lots of 0.01 (ie, 1 cent)
