I mainly reported a few issues with WB: First, the platform’s profiteering spreads caused the “small fluactuation market”, investors “scalped” back and forth, and most of the profits were taken away by the platform. For WB's MT4 gold (marked as "GOLD" in the system), the spread of 0.1 standard lot is 5 dollars, and the spread of silver (marked as "Silver" in the system) is 20 dollars; every fluctuation of silver (0.01 dollars) is 5 dollars, while gold is $0.5; while spot silver (XAGUSD.S) of the same species only needs a spread fee of $15 in another platform CWG, and a fluctuation is $2.5, and gold (XASUSD.S) only needs 1.5 US dollar spread fee, a fluctuation of 0.1 US dollars, which is equivalent to 2 fluctuation and more expensive than silver, and 5 times more expensive than gold. Second, there are serious bug in the lock-up operation of the platform: I bought 0.1 lot of silver from Sell 22.13 on the WB mt4 platform. Due to the continuous rise in subsequent prices and the problem with the amount of my funds, I had to take the same amount to buy more Buy 0.1 lot of silver is 22.66, and because follow-up operations may have an impact on the long order, I closed the long position at 23:01 on 2022/12/07, with a loss of 25 US dollars, but the platform immediately triggered the stop loss, resulting in my empty order directly It was considered liquidated by the system and forced to close the position, and there was no money left in the end. Seriously affect subsequent operations
