Many people believe that retail investors can't make money because they don't understand the market. Actually, that's not the case.

The real killers are not here, but in four deadly psychological traps: greedily chasing high during rallies, getting scared and cutting positions during dips, trying to go all-in after a few losses to recover, and suddenly changing rules when the market moves against you. Sounds familiar, right? This is not a personality issue; it's human instinct in high-volatility environments—essentially unavoidable.

But how do automated trading systems work? It's very simple, just three points:

First, execute predetermined conditions—act when it's time to act, observe when it's time to observe, with no hesitation.

Second, risk control is fixed—stop loss when the limit is reached, never try to "prove yourself."

Third, rules are executed uniformly and never changed.

What is the effect of combining these three points? No greed, no fear, no rush, and no sudden desire to gamble everything. It may sound less clever, but in fact, it's more stable—and stability is everything in trading.

The future differentiation in trading is no longer about who has stronger analysis skills, but about who can minimize emotional interference. This is where the game rules are changing.
