The end of trading is not technology, but cognition.
Cognition determines how far you can go; technology is merely a cushion for how deeply you fall.
Many people spend all their time researching indicators and staring at charts, but overlook the fact that what truly sets people apart is the understanding of risk, awareness of market cycles, and respect for human nature.
Trading without a stop-loss is like a car without brakes - no matter how aggressively it starts, it is doomed to crash.
Those who can take profits are the experts;
Those who can stay in cash are the veterans;
Those who only know how to open positions are the tenderest shoots among the chives.
A truly mature trader does not chase trends, does not gamble on emotions, but remains calm at critical points and protects their capital.
