The biggest enemy of manual trading is often oneself. Fear causes people to miss opportunities, while greed makes it hard to withstand losses. Instead of decisively cutting losses, they hesitate; instead of locking in profits, they keep adding positions—this is where quantitative robots come into play. They don't get tangled up, don't regret, and are never swayed by candlestick charts. As long as the strategy is written into code, the robot can execute every buy and sell signal without hesitation—decisive when buying, firm when selling. This mechanical discipline is precisely what many retail investors lack—consistent strategy execution, zero emotional interference, and trading logic that remains unchanged.
