There is a frequent dead system and slippage with USGFX . My account was 2001997766, in which all orders were canceled. Now I will reveal all the evidence collected. At 16：47：53, January 6th, I placed US30 at 28388.05 for 6 lots or so, but failed. The No. was 45717092. So I changed it into 28283.65 at 16：54：58, which was eventually evacuated. The data was interrupted during 16:50 to 17:09, during which the price decreased to 28384, thus my order should be effective. Now the price has exceeded 29000, which could bring a 20 thousand dollars profits. There is slippage with every single order on crude oil, as well XAU/USD since January 6th. Each order would cause a $50 to $100. Sometimes, the position-opening was even unavailable. I require USGFX to compensate all my losses.
