i am sorry to have to correct you but........ a round trip on a fixed price of 1 pip costs errr 1 pip !
you always must look at a trade as if you make buy and sell but the quote does not move. So if you buy at 1.30453-1.30463 in the Eur/Usd and then sell on the same quote a second later the cost will be one pip.
on a commission based market you will pay on both legs so the 'cost' is doubled around the spread. possibly to be more accurate i should have said
CFD Trading | CFDs | Contract for Difference | Capital CFDs rather than capitalspreads.
I really do have to laugh sometimes at the preconceptions here. There is always someone on the other side of your deal whether with IB or FXCM. At Capitalcfds we take 16 FX liquidity providers (the sixteen biggest) average it to a 1 pip spread and just put the price out to clients. The idea that cfd providers manipulate prices is just fanciful.
i have two traders looking after 3000 markets taking over 30k trades a day. They are just not interested in over 99pc of trades/traders. all they look at is the position risk of the company. in reality the trades they look at are they large ones (i.e £1,000,000 value and over in FX). bear in mind the cfd/sb platform is for small retail clients not pros (for whom we have several bespoke FX platforms tailored to taste!)
