The profit and loss ratio is the key to stable trading profits — a data model that helps you understand why a high win rate isn't enough

Many traders are obsessed with chasing high win rates but overlook a more critical metric: the risk-reward ratio. In fact, even if your win rate is below 50%, as long as your risk-reward ratio is set properly, you can still achieve consistent profits. Today, we’ll thoroughly explain this issue with data and examples.

What Is the Risk-Reward Ratio? Why Is It Often Overlooked?

The risk-reward ratio is easy to understand literally — it compares the profit per trade to the loss per trade. More specifically: before entering a trade, you determine how much you are willing to lose (e.g., $10), and then estimate how much profit the trade could bring you (e.g., $15 or $20). The ratio of these amounts, like 15:10 or 20:10, is the risk-reward ratio.

Most beginners make the mistake of focusing too much on win rate. They think, “If I can win 60% of my trades, I’ll be profitable, right?” But in reality, a 50% win rate combined with a 2:1 risk-reward ratio is far more profitable than an 80% win rate with a 1:1 ratio.

Ironically, many traders don’t even know their true risk-reward ratio. They only look at their final account balance, never calculating the specific profit and loss ratios of each trade. It’s like driving without checking the fuel gauge — eventually, you’ll run out of gas.

The Perfect Formula for Risk-Reward Ratio and Win Rate

Let me illustrate this with a simple table. Suppose your trading pool is $100, risking only $10 per trade (risk management is key).

Key formula:
Expected value = (Risk-Reward Ratio × Win Rate) – (1 – Win Rate)

Here are some examples:

• Risk-reward 1:1 requires a 60% win rate to be profitable
• Risk-reward 1:1.5 requires a 40% win rate
• Risk-reward 1:2 requires about 33% win rate
• Risk-reward 1:2.5 requires about 28% win rate
• Risk-reward 1:3 requires about 25% win rate
• Risk-reward 1:5 only needs about 17% win rate to be consistently profitable

See why the risk-reward ratio is so important? For 100 trades, someone using a 1:2 ratio needs to get about 33 correct trades, while another using 1:1 needs 60 correct trades. Clearly, the former has a lower threshold and is easier to execute.

Data Analysis of Risk-Reward Ratios: How Much Win Rate Do You Actually Need?

Let’s look deeper into what these numbers mean. Suppose you make 10 trades, risking $10 each time:

Scenario with 10% win rate (1 win, 9 losses):

• Risk-reward 1:1: Profit $10, loss $90, total loss $80
• Risk-reward 1:2: Profit $20, loss $90, total loss $70
• Risk-reward 1:5: Profit $50, loss $90, total loss $40

Scenario with 30% win rate (3 wins, 7 losses):

• Risk-reward 1:1: Profit $30, loss $70, total loss $40
• Risk-reward 1:2: Profit $60, loss $70, total loss $10
• Risk-reward 1:3: Profit $90, loss $70, net profit $20

Scenario with 50% win rate (5 wins, 5 losses):

• Risk-reward 1:1: Profit $50, loss $50, break-even
• Risk-reward 1:1.5: Profit $75, loss $50, net profit $25
• Risk-reward 1:2: Profit $100, loss $50, net profit $50

You see, even with only a 50% win rate, as long as your risk-reward ratio is 1.5:1, you start making a profit. This explains why some traders seem to have mediocre win rates but still grow their accounts — they understand the secret of risk-reward.

Practical Application: How to Set Reasonable Risk-Reward Goals

Before entering a trade, ask yourself three questions:

1. What is the maximum loss I am willing to accept?
For example, set a maximum loss of $10 (your stop-loss). This determines your stop-loss placement.

2. What is my profit target for this trade?
Look at the market — can you realistically aim for $15 or $20? If so, your risk-reward ratio is 1:1.5 or 1:2.

3. Is this ratio worth taking the trade?
Based on your current win rate. For example, if your recent win rate is 40%, then a 1:1.5 risk-reward ratio meets your profit criteria. Conversely, if you can only achieve a 1:0.8 risk-reward ratio, skip the trade.

Once this process becomes habitual, you’ll find that the outcome of your trades is largely decided before you even enter.

Common Misconceptions: Fake High Win Rates Are Destroying Your Account

Many fall into a trap: seeing six consecutive winning days with a 100% win rate, they start to inflate their confidence. But in reality, this is just because their trading frequency is too low.

The danger of small sample sizes:
If you only make 4 trades a week, your win rate looks perfect. But over a month or quarter, the true win rate will reveal itself. Statistically, you need at least 100 trades to see the real trend.

Conversely, some think their win rate is too low but trade too frequently. Doing dozens or hundreds of trades daily, jumping into every signal, is gambling, not trading. In such cases, a low win rate is normal because you’re not applying disciplined filtering.

Ideal trading rhythm:
There’s no fixed rule like “make X trades per week.” The real principle is: don’t trade unless you’re confident. If your mind is torn — one part saying “it will fall,” another “it will rise” — skip the trade. Only when you’re very sure about the market direction should you enter.

Over time, you’ll discover your strengths: some excel at range breakouts, others at trend-following, some at bottom-fishing. Play to your strengths, and both your risk-reward and win rate will improve.

Record Data to Discover the Truth

A underrated habit is to record every trade. You don’t need complicated spreadsheets — just note down:

• Entry time and price
• Your predefined stop-loss (risk)
• Actual exit point
• Final profit or loss

After a month of consistent recording, you’ll see your true win rate; after three months, your risk-reward ratio; after six months, which trading styles suit you best.

Then, the next step is optimization. The simplest way to improve your risk-reward ratio is to let your profitable trades be more profitable and keep your losses controlled. This requires more precise entries and scientific target setting, not blindly chasing higher win rates.

The concept of risk-reward ratio seems simple, but few can truly internalize and execute it in practice. Most traders are still stuck asking “Why is my win rate low?” without considering that improving the risk-reward ratio might be a more direct solution.

Keep this framework in mind as the foundation of your trading decisions. No matter how markets fluctuate or how others boast, you can evaluate each trade based on risk-reward logic. Persist long-term, and you’ll find your trading career takes a new direction.
