Risk/Reward: Is the Trade Worth Taking?
What You'll Learn
- What a risk/reward ratio actually compares
- How it's typically calculated
- Why a favorable ratio doesn't guarantee a winning trade
The Big Idea
Let me teach you risk/reward. It compares how much you stand to lose if a trade goes wrong against how much you stand to gain if it goes right. It is a ratio that helps you judge whether a specific trade's potential upside reasonably justifies its planned downside, before you ever enter it.
Let's Break It Down
The calculation compares the distance from your entry to your planned stop-loss, your risk, from earlier in this module, against the distance from your entry to your planned target or take-profit level, your potential reward. A risk/reward ratio of 1:3, for example, means the potential reward is three times the size of the risk being taken.
This ratio is evaluated before entering a trade, alongside, not instead of, the position sizing already covered in this module. A more favorable ratio means a smaller potential gain is needed to justify the risk being taken. A less favorable ratio means a larger potential gain is needed to justify the same risk.
I need to be precise about a genuine limitation here: a favorable risk/reward ratio says nothing on its own about how likely the trade is to actually reach its target. A trade with excellent risk/reward can still lose more often than it wins. The ratio describes the shape of a potential outcome, not the probability of achieving it.
Real Example
A lottery ticket can have an enormous risk/reward ratio — a small cost against a potentially huge payout — while still being extremely unlikely to actually pay out. A favorable ratio alone says nothing about how often that favorable outcome is likely to actually happen.
Why It Matters
Risk/reward gives you a concrete way to evaluate whether a specific trade's setup is worth taking. But understanding its real limitation — that it says nothing about probability on its own — is essential context heading into the next lesson on drawdowns, where I cover the actual math of losses over many trades directly.
Common Mistake
Please do not treat a favorable risk/reward ratio as a guarantee the trade will be profitable. It describes the shape of a potential win versus a potential loss, not how likely either outcome actually is to occur.
Quick Check
What does a risk/reward ratio of 1:3 mean?
Key Takeaways
- Risk/reward compares the planned potential loss against the planned potential gain on a trade.
- A more favorable ratio means a smaller potential gain is needed to justify the risk taken.
- A favorable ratio doesn't indicate how likely the trade is to succeed — it describes the shape of the outcome, not its probability.
