In the world of financial markets, few principles are as profound and transformative as the concept that profit and loss originate from the same source. This idea—often referred to as "盈亏同源" in Chinese trading circles—is not just a philosophical observation; it's a foundational mindset that separates novice traders from seasoned professionals. At its core, this principle teaches us that every strategy, decision, or market move that generates profit also inherently carries the potential for loss. You cannot have one without the other.
Understanding this truth begins with a critical mental shift: letting go of the illusion of certainty. Many new traders enter the market seeking guaranteed outcomes—patterns that always work, indicators that never fail, or strategies with 100% win rates. But such certainty doesn’t exist in dynamic, probabilistic environments like crypto, stocks, or forex. The pursuit of absolute predictability leads only to frustration, over-optimization, and ultimately, failure.

Why Certainty Is a Trap in Trading
Markets are complex systems influenced by countless variables—economic data, geopolitical events, investor sentiment, liquidity flows, and even algorithmic behavior. No single trader can control or perfectly predict these forces. Yet, many still chase "holy grail" setups or backtest strategies into oblivion, hoping to eliminate all risk.
But here’s the paradox: when you try to remove risk completely, you also eliminate the possibility of reward. Every edge in trading comes with built-in uncertainty. A trend-following system profits during strong moves but suffers in choppy markets. A mean-reversion strategy wins when prices bounce but loses during breakouts. The source of your gains is the same mechanism that exposes you to losses.
This is what “盈亏同源” truly means—your winning trades and losing trades come from the same strategic root. Accepting this duality allows you to stop blaming losses on bad luck or flawed execution and instead focus on consistency, position sizing, and long-term expectancy.
The Yin and Yang of Market Psychology
Think of trading like a太极 (Tai Chi) circle—half light, half dark, constantly rotating. Risk and reward are not opposites; they are interdependent forces. Just as day turns into night and back again, winning streaks give way to drawdowns, and volatility creates both danger and opportunity.
Traders who constantly avoid risk—jumping out of positions at the first sign of red candles or news noise—are unknowingly avoiding the very conditions under which their strategies succeed. If your system requires riding through minor pullbacks to capture major trends, then exiting early out of fear ensures you’ll miss the big wins.

Building a Sustainable Trading Mindset
So how do you apply the "profit and loss share the same origin" principle in practice?
1. Focus on Process Over Outcome
Instead of judging each trade by whether it made money, evaluate it based on whether you followed your rules. Did you enter at the right setup? Was your position size appropriate? Did you manage risk according to plan? Over time, a solid process leads to positive results—even if individual trades lose.
2. Embrace Drawdowns as Part of the Journey
Losses aren’t failures—they’re tuition fees for market education. Every drawdown tests your conviction and discipline. The best traders don’t fear losing; they fear inconsistency.
3. Optimize for Long-Term Expectancy
Rather than chasing high win rates (which often come with small gains and rare catastrophic losses), aim for a positive risk-reward ratio. For example, losing on 6 out of 10 trades but making 3x more on winners than losers creates profitability.
4. Avoid Overfitting Your Strategy
When you tweak a strategy to avoid past losses, you risk making it too specific to historical data. That may look great on paper—but fail in live markets. Remember: removing past losses often removes future profits too, because both stem from the same market behavior.
Frequently Asked Questions (FAQ)
Q: Can I ever eliminate risk and still make money?
A: No—risk is inseparable from return. Even "safe" assets carry inflation or opportunity cost risks. In trading, zero risk means zero edge.
Q: If losses are inevitable, how do I protect my account?
A: Use strict position sizing, stop-losses, and diversification. Protect capital not by avoiding losses entirely, but by ensuring no single loss can cripple your portfolio.
Q: How do I know my strategy has a real edge?
A: Test it across multiple market conditions, measure its risk-adjusted returns (like Sharpe ratio), and ensure it aligns with sound market logic—not just curve-fitted data.
Q: Should I change my strategy after a string of losses?
A: Only if you’ve broken your rules. If you followed your process, stay consistent. Short-term results don’t define long-term success.
Q: Is crypto trading different when it comes to risk-reward balance?
A: While crypto is more volatile, the core principles remain unchanged. High volatility increases both risk and potential reward—but disciplined execution is even more crucial.

Final Thoughts: Mastering the Duality
The journey to becoming a mature trader isn’t about finding a perfect system—it’s about developing resilience, clarity, and acceptance of market reality. When you internalize that profit and loss are born from the same source, you stop fighting the market and start working with it.
You begin to see drawdowns not as setbacks but as signs that your strategy is operating as intended. You stay in winning trades longer because you understand that volatility is part of the payoff. And most importantly, you trade with confidence—not because you know what will happen next, but because you trust your process regardless of outcome.
Let go of certainty. Embrace uncertainty. And let the balance of risk and reward guide your path forward.
