$SUI No one is willing to lose, but one must learn the art of losing.

Those who trade must understand that losses cannot be completely avoided; stop-losses are inherently part of trading.

What truly causes emotional instability is not the stop-loss itself, but poor position management—when losses exceed expectations, people tend to panic.

Before opening a position, a strategy must be established; after opening a position, it should be executed mechanically, unless there is a clear deviation signal.

Because when holding a position, there will be expectations, biases will shift, and one will unconsciously downplay opposing signals while amplifying positive ones, often leading to less rational decisions compared to when one is out of the market.

Therefore, the basis for opening a position must be clear and sufficient; after opening a position, do not constantly monitor it; continuous analysis is sufficient.

There are four main principles for opening a position: first is the basis (technical signals); second is the stop-loss line (key support or resistance levels); third is the expected target (profit-taking range); fourth is the worst-case scenario (good position management).

Regarding profit-taking, open profit-taking is not suitable for a full position. The market will eventually reach an end; one can only earn money within their understanding.

Many times, when the market reaches the expected range, due to greed, profits are not taken, prices reverse, and gains turn into losses, resulting in a double blow.

Therefore, one can take profits in stages or keep a base position; the expectations set before opening a position must be executed, and any excess is considered unexpected wealth, so do not become attached.
