Hi gle101,
Happy to be here. Brokers and spread betting firms offer the same product, forex trading, but there are two methods of execution: market maker and direct market access (no dealing desk, straight through processing).
The majority of spread betting firms are market makers. They take the other side of all positions thereby profiting when you lose, and losing when you profit. This is a conflict of interest because it is in your broker’s best interest for you to lose money. Since a market maker can profit if the market moves against you, it is also common to get referred to a dealer when the price is unfavorable to the market maker. A good example of this is news trading.
With FXCM, every single order is sent directly to one of the 9 banks quoting on our system. As a result, FXCM does not profit when you lose money on a trade. Rather, we are compensated by marking up the price we receive from the bank. Thus, FXCM is strictly concerned with volume. Because of this there are no restrictions on trading styles or strategies such as scalping or news trading. There are no re-quotes.
