After Feb. 28, FXCM's CFDs will be trading 1/10th lots, meaning that where before 1 lot US30 would equate to $1 per price tick, after Feb. 28. 1 lot will equate to $0.10 per price tick, requiring a margin on $9 instead of $90.

How will this affect Z strategies that trade CFDs? FXCM will automatically update open trades, but will the Z systems open 10 lots where they previously opened 1 lot?
