Brothers, there's no need to ask too much why unrealized gains increase the position, why there's a sudden loss and reduce position, or why entering a position didn't earn and directly closed out, etc. I won't answer each question individually because all my accounts on several platforms are unified. Increasing the position is just looking at the signals, reducing the position is just that the situation is not right, preserving strength for the next key position, closing out for a little profit is just that there’s no confidence in this order, closing out for a small amount, or just to get a feel for the market. Because focusing on trading requires blocking out noise, including the fact that the market has many smokescreens, including favourable information suddenly dumping, unfavourable information leading to a reverse pump. So many people lose money because they stop loss when they shouldn't and hold on when they should stop loss.
