Understanding Risk-Reward: Not Just a Ratio
It's easy to look at a 1:2 or 1:3 risk-reward ratio and think you've got a winning strategy. But often, traders oversimplify this concept. The raw ratio only tells part of the story; it needs to be weighed against your win rate. A 1:3 ratio is great, but if your win rate is only 20%, you're still likely to be underwater over a series of trades.
Conversely, a 1:1 risk-reward can be perfectly viable if your win rate is high enough – say, 60% or 70%. The real power of understanding risk-reward is in combining it with your typical win rate to calculate your expected value per trade. This provides a more realistic picture of profitability over time, rather than fixating on just one component. For example, chasing a 1:5 on $SI right now when it's up +5.42% intraday could mean setting an unrealistic target that's rarely hit, despite looking good on paper. It's about achievable targets relative to your stops, not just arbitrary numbers.
จริงเลยครับ หลายคนมองข้ามเรื่อง Win Rate ไปเยอะ คิดแค่ Risk-Reward สูงๆ ก็พอแล้ว แต่สุดท้ายก็เจอน้ำท่วมปอดกันเป็นแถว ยิ่งถ้าไปเจอ Slippage หนักๆ นี่จบเลยนะ
