$RIVER's recent price movements have sparked quite a bit of discussion—some are asking whether they can recover costs through profit sharing. From the actual market data, investors who entered at 1:30 experienced fee deductions by 2:00, with current paper profits of $250, while the fee cost was only $35. This reflects a key issue in the trading mechanism behind it.

Many people still have a superficial understanding of fee sharing. When the fee is activated, the robot has already automatically closed the position—closing a long position is equivalent to selling. Do you think you can react faster than the robot? The reality is that retail investors simply can't keep up. The robot executes at millisecond speeds, while you're still contemplating whether to follow.

The result is: those investors who try to chase the high and reap fee dividends end up waiting for a waterfall sell-off. This isn't a market problem, but a lack of understanding of the trading mechanism among participants. To participate in such mechanisms, you must understand the underlying logic; otherwise, you're just gambling on probabilities, and probabilities often don't favor latecomers.
