A mature trader is never the type who "never loses."

What truly makes a difference is who can keep losses within an acceptable range.
If you don't want your trading career to end abruptly, the first thing is not to study complicated indicators, but to implement risk management effectively.
Without risk control, even the best market conditions and high win rates can be shattered by a single out-of-control operation.
Only by surviving first are you qualified to talk about profitability.
Long-term survival allows the strategy's advantages to gradually manifest over time.
What you need to do is not copy others or gamble on directions, but:
Build a trading system that is uniquely yours,
Test it through backtesting to verify if it truly has a positive expectation,
And then use rules to constrain yourself, with position sizing and stop-losses to protect your account.
