Since the trading target changed from Insider Brother to the leader Brother James, I have discovered a significant issue. James tries to avoid continuous market impact when opening and closing positions, so he operates in multiple time segments separately. This results in following him only being able to capture a small amount of profit, or even no profit at all, especially with the BTC trading pair. Additionally, due to the erosion of transaction fees, the profits are far below expectations, which has also lowered my overall win rate.
