re the broker, LMAX spreads are good, better definitely than Dukascopy (especially Gold), FXCM, FxPro, Gain Capital/Forex.com, CMS, Saxo Bank (which is a joke considering they are a bank).... let's see, did i manage to piss off enough dealers?
BUT RJOBrien (UK)/Integral as better spreads.
and both have stellar execution, but RJObrien/Integral LPs have last look, whereas on the LMAX Exchange, the LPs have no last look so once your order is matched against a LP, the LP cannot back out of the trade anymore--no funny business in that regard.
and yes, commissions but they are competitive and spreads are variable of course.
hope this helps.
all the best.
