Hi jcl. FXCM has told me there is another account type available through an un-regulated subsidiary called FXCM Markets. These accounts are not currently scheduled to get the new currencies rates at all, but pay 5% interest on average Usable Margin, paid monthly.

A few questions:

a) Since CFD's are unchanged by the new rate structure, this seems like a no-brainer for trading Z3?
b) Is there an easy way to account for this interest in Testing results? Or would it need to be an additional after-Testing calculation?
c) If the latter, is there a way to easily get Usable Margin figures for the life of the equity curve?
d) If not, what summary variables within Test provide the simplest path to calculate it? Something like store each month's average (Equity-UsedMargin), and then at the end loop back and add CR to all the values?
e) Wondering if it makes any sense to consider this account for Z12 &/or Z5?

Thanks.
