The concept of profit and loss ratio

Let me fully understand the concept of Risk/Reward Ratio:

1. Basic Definition:

- The ratio of potential reward to potential risk

- Usually expressed as possible profit points / possible loss points

2. Practical Application Considerations:

- Estimation of upside potential

- Assessment of downside risk

- Win rate factors

- Support and resistance levels

3. MSTR Case Analysis:

- Significantly increased as of 11/21

- Limited room for further increase

- Higher downside risk

```

Let me give a specific example using MSTR:

Assuming on 11/21 the MSTR stock price was at $500:

1. Risk Calculation:

- The nearest strong support level is at $400

- Potential downside risk = 500 - 400 = 100 points

2. Expected Reward:

- Technical resistance level is at $550

- Potential upside = 550 - 500 = 50 points

3. Risk/Reward Ratio Calculation:

- Risk/Reward Ratio = 50:100 = 0.5:1

- This means for every unit of risk taken, only 0.5 units of reward can be obtained

4. Risk Assessment:

- Risk/Reward Ratio is less than 1:1

- Even with a high win rate, it is difficult to achieve long-term profitability

- Does not meet good trading criteria

A better trade should be:

1. Ideal Risk/Reward Ratio:

- Should reach at least 1:1

- It is recommended to pursue 2:1 or higher

- For example, risk 50 points, target reward 100 points

2. Practical Operation Suggestions:

- Wait for a pullback near the support level

- Set a reasonable stop-loss level

- Ensure there is enough upside potential

3. Specific Calculation Method:

```

Risk/Reward Ratio = Target Reward Points / Stop-Loss Points

Example:

Buy Price: 450

Stop-Loss Price: 400

Target Price: 550

Risk/Reward Ratio = (550-450)/(450-400)

      = 100/50

      = 2:1

```

Important Reminders:

1. Trading Discipline:

- Always consider risk first

- Do not chase prices or panic sell

- Wait for high win rate and high risk/reward ratio opportunities

2. Pre-Opening Checklist:

- Technical support

- Fundamental analysis

- Risk/Reward Ratio calculation

- Risk control plan

3. Common Misconceptions:

- Only looking at upside potential

- Ignoring downside risk

- Not calculating risk/reward ratio

- Pursuing high win rates while ignoring risk/reward ratio

4. Best Practices:

- Look for opportunities with a risk/reward ratio greater than 2:1

- Ensure there is a clear stop-loss level

- Build positions near support levels

  • Build positions in batches and take profits in batches

Remember: Good trading opportunities are waited for, not chased. High risk-reward trading opportunities often appear during market panic or pullback periods, rather than when hitting new highs
