Almost all greed and fear in the market fundamentally stem from two words: ignorance and the incompetence caused by ignorance.

When you lack a clear judgment system,
no repeatable technical basis,
and no understanding of trends, positions, or rhythm,
every buy and sell becomes a psychological game of emotions.

Thus, the two most typical fears emerge:
• Not daring to sell when in profit, afraid of "selling too early,"
• Not daring to cut losses when in loss, afraid of "cutting too deep."

On the surface, it appears that greed and fear are dominating the operations;
in reality, you simply don't know what you're earning or losing.

When you don't know whether this money is made through trends or luck,
you can't feel at ease when selling.

Because you can't judge:
• Is this a main upward trend, or just the tail end of a rebound?
• Is this a normal correction within the trend, or has the trend already broken?
• Should you lock in profits, or continue holding?

Without judgment ability,
you can only place hope on "a little more rise" or "another chance,"
and trading naturally turns into prayer.

The same applies to fear.

When you don't know where your stop-loss logic is,
don't know if the loss is within controllable limits,
and don't know if this trade has already "lost its logic,"
you can only fight uncertainty with "toughing it out."

The typical results are:
• Unwilling to stop small losses
• Becoming numb to medium losses
• Being forced to accept large losses

This is not a personality issue,
but a mismatch between ability and risk.

Truly mature traders, in fact, have the least emotional fluctuation.

It's not that they lack greed and fear,
but that they clearly understand:
• When to take profits
• When to exit
• How much they might lose at most if wrong
• How much they can roughly earn if right

When everything has rules, boundaries, and expectations,
emotions naturally lose their dominance.

Greed is when you don't know where profits come from;
fear is when you don't know where the risk boundaries are.

When you start replacing emotions with cognition, systems, and techniques,
the market for you
is no longer a psychological torment,
but a probabilistic game that can be continuously refined and evolved.
