After the account is profitable, IC starts to add dark points. Several of my accounts are like this. The video on the left is normal, while the right side has dark points added. Please note that the difference between the price when placing an order on the right side of the video and the price at the time of execution is always around 0.3. The exits are the same. Moreover, I was trading when the price fluctuations were not significant, not within an hour before or after the close, during the European session, which means trading normally at three or four o'clock in the afternoon Beijing time. In addition, the account on the left was also trading at the same time, and its spreads were always normal. If it was slippage, it wouldn't be the case that every time it slips in the opposite direction. Even after placing several consecutive orders, there should also be positive slippage, but it only slips in the opposite direction.
