The longer you trade, the more you realize: holding on stubbornly after being trapped, adding to positions as it drops, is not contrarian trading, but completely following human instincts.

Behavioral economics has long concluded: the pain of losing 100 yuan is 1.5 to 2 times the pleasure of gaining 100 yuan. So most people, after losing, are obsessed with "getting back to even," unwilling to accept losses calmly, always trying to make every trade "not lose"; and even less willing to cut losses and exit, because stopping loss feels like admitting a mistake publicly, intertwining pride and luck, hardening shallow traps into deep ones.

The real test of skill, the truly counter-human operation, is never adding to a losing position against the trend, but daring to admit mistakes and decisively cut losses. When the trend turns bad and the trading logic no longer exists, exit immediately to cut losses, rather than deluding oneself with the hope that "it will bounce back if I wait longer."

The same applies to profits. The human nature-aligned approach is to take profits quickly and lock in gains, ending up with only small crumbs; while mature traders rely on trends and rules to patiently hold, letting profits run.

Trading along with emotions always results in earning small amounts and losing big ones. In the end, technical skills are fundamental, risk control is the bottom line, and fighting against human greed, fear, and luck is the true ongoing discipline.
