1. What is Risk-to-Reward Ratio?
The Risk-to-Reward Ratio (sometimes written as R:R) is a tool that helps traders decide if a trade is worth taking.
Risk = how much you are willing to lose on a trade (your stop-loss distance).
Reward = how much you expect to gain (your take-profit distance).
👉 Example: If you risk $100 to potentially make $300, your R:R = 1:3.
2. Why is it Important?
Trading is about probabilities, not certainties.
Even if you lose more trades than you win, a good R:R can still make you profitable.
It helps you control emotions and avoid gambling behavior.
3. How to Calculate It?
Formula:
R:R=Potential Reward / Potential Risk
Step 1: Decide entry price.
Step 2: Set stop-loss (where you cut losses).
Step 3: Set take-profit (your profit target).
Step 4: Calculate ratio.
Example:
Buy a stock at $50
Stop-loss at $48 → risk = $2 per share
Take-profit at $56 → reward = $6 per share
Ratio = 6 ÷ 2 = 1:3
4. What Ratio is “Good”?
Many day traders aim for at least 1:2 (risking $1 to make $2).
Scalpers might accept 1:1 if win rate is very high.
Swing traders may go for 1:3, 1:4, or more.
5. Example in Real Trading
You take 10 trades with R:R = 1:2.
Win only 4 trades, lose 6.
Wins: 4 × $200 = $800
Losses: 6 × $100 = $600
Net: + $200 profit (even with only 40% win rate!).
6. Common Mistakes Beginners Make
❌ Setting take-profit too close, but stop-loss too wide.
❌ Moving stop-loss further away when trade goes bad.
❌ Not calculating R:R before entering.
✅ Key Takeaway:The Risk-to-Reward Ratio is your safety net. It ensures that you don’t need to win all the time to still make money.
