Personnaly I wouldn't go for a broker (whoever it is) with 1 pip spread on the cable and 0 commissions.
The interbank spread on the cable can be bigger than 1 pip (check with an ECN), then if they would pass actual orders they will loose money in such cases.

Of course they don't pass your trades and they take the counterpart but anyway they have to make money. So if they don't make money from the spread they have to make it from somewhere else.
For me it seems that for them to stay alive the MUST have a large number of customers loosing their money.
I know that the stats are here to confirm that (but the stats maybe different with 1 pip spread only) but anyway they have to insure somehow that people are loosing.
Or did I miss something?
