Roberk,
They only make money on the spread
for the trades they can match and not
all trades can be matched ;
to match all trades,there has to be
exactly the same amount of size
on both sides bid/ask at all times
For the trades that can't be matched, they
take the other side of the losing traders
and the winners are sabotaged because
those trades need to be offset in the
interbank market otherwise the broker
has to pay out of his own pocket.
That's why they don't like scalpers because they don't have the time to offset.(How you can offset a mini-
contract in the interbank market ? you
CAN'T)
Matching works on automatic,taking
the other side of losing traders also.
the hardest clients are the winning
scalpers and least amount of profit
their spread minus interbank spread
(if they offset at all)
But why would they match losing
traders if they can make more by ta-
king the other side ??
The biggest money is made from taking the other side of the 95 % of losers, second place from the matching(the
spread) and third from the winning
traders (spread minus interbank spread if they offset at least)
They have to make sure that the money those 5 % winners make is
coming from the interbank market and
not out of their own pocket if they cannot
offset.
So there is indeed a HUGE conflict
of interest !
