In the world of trading, one of the forex scams is based on the manipulation of bid/demand spreads by broker. Basically, the point spread between offer and demand reflects the commission of one intermittent transaction processed through a broker. These spread scams are usually altered without being detected by the trader.
These scams have become less active over the past 10 years, where brokers have been the target of regulatory scrutiny. Any broker is also at risk for spread fraud unless you can ask a skilled and experienced trader.
Choosing the right broker is very important to become a trader .
