Understanding RR in Trading: From Theory to Practical Application

When it comes to trading or investing decisions, most traders tend to focus on the expected returns. However, the actual risks involved are equally important. One way to help traders visualize this clearly is by using the RR (Risk Reward Ratio), which is not a complicated formula but a powerful tool that can significantly influence decision-making.

What is RR and Why Is It Important?

Risk Reward Ratio or RR describes the comparison between the amount we risk losing (risk) and the expected (reward). This metric indicates whether a trade is worth taking based on its potential reward relative to its risk.

A clear example: Suppose you have two trading options:

Option 1: Enter a position that could yield a 20% profit but might incur a 50% loss.

Option 2: Trade an asset with a 10% profit potential but only a 5% risk.

At first glance, Option 1 seems better. But when calculating RR, the second option has an RR of 2, while the first has only 0.4. This means that if you succeed with Option 2, your reward is much more favorable relative to your risk.

How to Calculate RR Correctly

The basic formula for RR is straightforward:

RR = (Target Price – Entry Price) / (Entry Price – Stop Loss Price)

Let’s break down each component:

• Entry Price: The price at which you decide to buy
• Target Price: The price you expect the asset to reach
• Stop Loss Price: The point at which you are willing to exit to limit losses

( Practical Application

Let’s look at a concrete example. Suppose you’re interested in trading BTS )shares of BTS Group Holdings Limited(, currently priced at 7.45 THB.

• You set a target at 10.50 THB
• You place a Stop Loss at 4.50 THB

Plug these into the formula:

RR = (10.50 – 7.45) / (7.45 – 4.50)
RR = 3.05 / 2.95
RR ≈ 1.03

This calculation indicates that if the trade succeeds, you stand to gain approximately 1.03 times your risk, making it a worthwhile trade.

Types of Risks Traders Should Know

Before trading, it’s essential to understand that risks come in various forms:

Liquidity Risk – The risk of not being able to buy or sell at the desired time.

Correlation Risk – When multiple assets move together, reducing diversification benefits.

Currency Risk – Fluctuations in exchange rates affecting your holdings.

Interest Rate Risk – Changes in interest rates impacting asset values.

Inflation Risk – Inflation eroding purchasing power.

Political Risk – Political events negatively affecting markets.

What Is an Appropriate RR: How Much Is Worth It?

Most professional traders recommend that a good RR is 2 or higher, as it clearly indicates favorable risk-reward balance.

• RR = 1:1 – Risk equals reward; suitable for conservative traders but not ideal for profit growth.
• RR between 1 and 2 – Moderate balance; suitable for traders willing to accept some risk.
• RR greater than 2 – Reward significantly exceeds risk; suitable for confident, skilled traders.

However, an excessively high RR might also imply lower probability of success, so balance is key.

The Relationship Between RR and Win Rate

Smart trading involves considering RR alongside your Win Rate )percentage of wins###. These two factors are inversely related:

• To achieve a high RR (e.g., 3:1), your Win Rate might need to be around 25%.
• Conversely, accepting a lower RR (e.g., 1:1), your Win Rate could be around 50%.

( Example Calculation

Suppose you use RR = 3:1 and Win Rate = 25% over 100 trades:

• 25 wins × 3 )profit( = total profit of 75
• 75 losses × 1 )loss( = total loss of 75

Net result = 0 )break-even(

This means, to be profitable, your Win Rate must be higher than 25%.

Types of RR and Their Usage in Trading

( RR = 1:1
Results in equal risk and reward; suitable for beginners but not ideal for sustainable income.

) RR > 1 (e.g., 1.5:1)
Reward exceeds risk; suitable for intermediate traders with confidence in their system.

RR > 2 (e.g., 3:1 or higher)

Significantly higher reward relative to risk; requires a tested system and good understanding.

Using RR for Risk Management

However, RR is not just a number; it’s a risk management tool. For example:

Suppose your acceptable risk per trade is 50% of your capital, and you trade an asset with an RR of 2.0.
You can set your Stop Loss at 50%. When the price hits that point, you exit and preserve your capital.

This approach helps you:

• Avoid total loss
• Maintain confidence over the long term
• Continue trading in subsequent opportunities

Summary: Why Is RR Important for Traders?

RR is the bridge between hope and reality. Using RR helps traders avoid impulsive trades and promotes calculated decision-making.

The importance of RR lies in helping to:

• Assess the value of each trading opportunity before investing
• Manage your portfolio systematically
• Maintain the necessary balance between Risk and Reward according to your own preferences

Professional traders agree: RR alone is not enough; it should be considered alongside other factors such as company stability, market volatility, system Win Rate, and personal strategy. By integrating all these elements, you can develop a sustainable and valuable RR.
