This is outrageous! I strongly urge you to avoid this broker. I placed a trade this afternoon, setting a trailing stop at 1.7050 to protect my profits. The price was clearly trading sideways at 1.7058, but the system suddenly forced my long position to close at 1.7062! I used FXBlue to monitor the spread, and Dupoin's spread shot up from 1.2 pips to 9.8 pips in 2:59:30 PM, then returned to normal after 12 seconds. Even worse, the price immediately shot up to 1.7080 after I closed my position, resulting in a $3,000 loss! It's simply artificial manipulation of the spread to exploit my stop-loss order!
