well, with the banks infrastructure at Fortis I doubt there will be much lacking. Remember that probably more than half of the UK arcades clear their trades through Fortis.
Look at it this way - for 20,000 roundtrips on LIFFE i'll be paying £0.74 at Refco, where at TCA/Fortis I'd be paying £0.64 - thats a difference of £2000 a month, for what?
I just want my trades cleared in the fastest, most reliable way possible - after that prime requirement, it all comes down to cost, I'd sooner that £2k be in my pocket, it isnt chump change after all, and my trades are paying for it.
Who do YOU think is the best Bureau out there, and why?
