tomcole, trader/god - thanks, appreciate the inputs / suggestions
just by way of feedback:
. i did ask for and obtain a couple of minor contractual 'improvements', altho not nearly as many as i was seeking to obtain (but thats no surprise), however nothing as far-reaching as what tomcole is suggesting unfortunately. perhaps if i were in their top 10 accts / partners list i'd stand a better chance, dunno... in any case, i tried, and got some, perhaps not enough but at least no regrets...
. in regard to segregation, what is becoming clear at this point is, they (my second-tier fx prime broker) definitely won't entertain the idea of "myname" designated client accts, the type that wld provide 100% safety of funds in the event of a broker default. no ill will there, its just that they too don't need the hassle (i once had to implement escrow type arrangements for a sale, i know exactly what they mean...), and they are not doing it for any of their other 11,000+ brokerage clients (all products, not just fx), therefore no offense taken...
no done deal yet but after a couple of negotiating rounds over the last 6 weeks, the lines are pretty much drawn here... it seems i am either going to have to settle for what they were offering earlier (see previous posts), i.e. 2 accts per client, 1 seg ("broker name" omnibus cust segregated acct) and 1 non-seg (utilized fx margin + yet tba) and the cross-margining / sweep agreement, or take my money/clients elsewhere
will i (settle)? most likely, yes, because of the overall T&Cs i am getting from them, the fact that their (audited) financials look good enough to me, their good UK-FSA record, their good rep ...
i tried hard but in the end i have to defer to the UK-FSA / the regulators more generally, to implement more comprehensive segregation-type measures on the spot fx mkt... am sure it will come in time, sooner than we think, thks to competitive pressures (of CME eFX products notably)! cheers
