What Is the Risk-Reward Ratio?

The risk-reward ratio (RRR) is a core metric that measures a trade’s potential loss (risk) relative to its potential profit (reward). Traders often use it as a vital tool to analyse whether any investment is worth the potential downside, even before opening the position. For working out this ratio, traders usually identify three particular price points for the trade. 

These include the entry price (the price at which you buy the asset), the stop-loss price (the pre-fixed exit point in case the market goes against you or the maximum you are willing to lose on the trade), and the target price (the pre-fixed exit point in case the market goes in your favour, indicating the anticipated profit). Let us learn more about it below, along with the vital concept of position sizing. 

The formula for the risk-reward ratio is as follows - 

Potential Loss (Risk) / Potential Gain (Reward)

Where,

Risk = Entry Price - Stop-Loss Price

Reward = Target Price - Entry Price 

An ideal ratio is usually considered at least 1:2 or 1:3. 

Example: 

Let’s say you want to purchase shares of a company. In this case, the following may apply: 

• Entry Price: You purchase at ₹500 per share. 
• Stop-Loss (Risk): You will set the stop-loss at ₹450 to limit your losses. 
• Risk = 500-450 = 50. 
• Target Price (Reward): You set your profit target at ₹650. 
• Reward = 650-500 = 150. 

Calculation:

Risk / Reward- 50/150 = 1:3. 

This is thus a healthy ratio, i.e., for every ₹50 you risk, you target ₹150 in profits. 

Key Points to Remember -

Remember that the RRR (Risk-Reward Ratio) is essential in trading; a more favourable ratio helps you remain profitable even with lower win rates. So, for a 1:3 ratio, you only have to be right just 25% of the time you trade to break even. This eliminates emotional decisions by offering an objective rule for trade entry and exit, while helping to combat capital erosion by keeping your losses minimal relative to your gains. 

1:2 is often considered the minimum standard for trading, while 1:3 or more is ideal for high-quality or swing trading setups, offering greater buffers against losses. 1:1 or lower is usually avoidable, unless you have an excessively high win rate above 60% or 65%. 

What is Position Sizing?

Position sizing is a necessary risk management technique that determines the specific number of units (contracts, shares, lots) to buy or sell for a given asset. It helps balance returns and risks, ensuring that potential losses from one trade do not negatively affect the trader's overall capital. 

Here are some key aspects of position sizing: 

• Managing Risks - Position-sizing targets, limiting losses on any one trade to a smaller percentage (1-2%) of the overall trading capital. 
• Size Calculation - This is done by dividing the total at-risk amount by the difference between the entry and stop-loss prices. 
• Combating Emotional Decision-Making - Consistent sizing improves discipline and reduces the risk of panic selling or impulsive market gambles. 

Here are some of its main components: 

• Account Risk - The total percentage of the trader's overall capital that they are willing to risk. It is often limited to a small percentage, i.e., 1-2% of each trade. 
• Trade Risk - The monetary difference between the stop-loss and entry prices. 

Position sizing safeguards traders against large losses, helping them withstand losing streaks more effectively. Traders can maximise their returns on successful trades while minimising their losses on losing trades. 

Why Risk-Reward and Position Sizing Go Hand-in-Hand

Risk-reward ratio (RRR) and position sizing go hand in hand, as they are essentially two sides of risk management. Position sizing is the primary tool for implementing the risk management strategy defined by the risk-reward ratio. Without combining these two aspects, traders may fail to manage risks effectively, regardless of how good the entry strategy is. Here are some key aspects that illustrate why they should be taught together: 

Interdependence 

One cannot function without the other. The risk-reward ratio helps traders determine whether a trade is worth going for. This is done by comparing potential profit to potential loss (aiming for at least 1:2 or 1:3). 

Position sizing determines the number of units to trade so that, if the stop-loss is triggered, the loss does not exceed a predetermined percentage of the account. If a trade has a high-risk RRR, the position size should be reduced. If it is too tight, then the position size may be increased while keeping the monetary risks the same. 

Better Emotional Discipline and Management 

Teaching them together helps ensure that the maximum potential loss is always known before entering the trade. Once you know that the position size is calculated properly based on the RRR, it will help prevent emotional or panic-stricken decision-making, especially for large positions. This helps you set and forget, removing impulses and anxiety from the whole process. 

Preserving Capital 

Many traders mistakenly set their position sizes and adjust stop-losses, leading to erratic, sizable losses over time. Teaching them together ensures a consistent risk per trade, safeguarding capital during losing streaks. Suitable RRR with position sizing helps traders stay profitable even when they win less than 50% of trades. 

Adjusting Dynamically to Volatility

In a volatile market, a wider stop-loss is necessary to avoid being stopped out early and to maintain smaller position sizes. In a calm market, a tighter stop-loss and a larger position may be more suitable. Traders can learn these concepts together to adapt more dynamically to evolving market conditions (e.g., adjusting position sizes relative to the RRR). 

Step 1: Define Account Risk per Trade

You should first define the maximum monetary amount that you are willing to lose on one trade. It is usually a percentage of the total capital, i.e., 1-2%. Thus, the Account Risk equals Total Capital × Risk Percentage. 

Step 2: Define Entry and Stop-Loss

You then have to define the account risk on a per-trade basis, along with the entry and stop-loss levels. You should also identify your trading parameters based on fundamental and technical analysis. The entry price is the level at which you will sell or buy, while the stop-loss is the price threshold at which you should exit to prevent any more losses. 

Step 3: Calculate Risk Per Share/Unit

This calculation is essentially the difference between the entry price and the stop-loss price. It indicates how much you stand to lose for each unit of your ownership. This will only apply if the trade moves against you. So, the Risk per Share equals the Entry Price minus the Stop-Loss Price. 

Step 4: Calculate Position Size

You can calculate the position size by dividing the total amount you are willing to risk by the per-share risk. This will indicate exactly how many units or shares you should purchase. So, the Quantity = Account Risk / Risk per Share. 

Step 5: Evaluate Whether the Reward Justifies the Trade

You should compare the potential profit (target – entry) to the potential loss (entry – stop-loss price). A healthy and standard ratio is 1:2 or 1:3 in this case. So, if you are willing to risk ₹500, you should aim for at least ₹1,000. 

Thus, the risk-reward ratio will be calculated as: Target Price – Entry Price – Stop-Loss Price. 

Scenario: a ₹1 lakh account, 1% risk, Stop-Loss-based position size - 

Suppose you have an account balance of ₹1,00,000 and want to trade a stock currently at ₹500 with a stop-loss at ₹490. You only want to risk 1% of your capital in this case. So, account risk in this case will be 1% of ₹1,00,000, i.e. ₹1,000. The risk per share in this scenario is 500-490 = 10. The position size will be 1,000/10 = 100 shares. 

If your target is ₹530, your potential reward can be ₹30 per share. Since the risk is ₹10, the risk-reward ratio is 1:3. This makes it a mathematically sound and healthy trade. So, for a ₹1,00,000 account with 1% risk, you should not be risking any more than ₹1,000 per trade. If the stop-loss distance is ₹10, then the position size should be no more than 100 shares. 

Common Mistakes and Best Practices

There are several common mistakes traders make with risk-reward ratios and position sizing. Some of them include the following: 

Risk-Reward Ratio (RRR)

Common Mistakes 

• Neglecting the RRR completely - This happens when traders focus solely on potential profits while overlooking the risks. 
• Setting unrealistic targets - Setting RRR objectives like 1:10 will only lead to adverse outcomes. You may miss opportunities or hold onto trades for too long. 
• Low RRR trades - Entering trades with a ratio of 1:1 or worse will necessitate a high win rate to stay profitable. 

Best Practices

• Keep a ratio of at least 1:2 - Only take those trades where the potential reward is double the risk at least. 
• Keep volatility in mind - Adjust your targets based on market conditions, i.e. wider targets in trending markets and tighter targets in ranging markets. 
• Leverage technical levels - Put stop-losses and take-profits at more logical resistance/support levels instead of arbitrary monetary amounts. 

Position Sizing 

Common Mistakes

• Overleveraging during trading - If you use excessive margin, it may magnify your losses and even wipe out your account in some cases. 
• Choosing the same sizes for all the trades - If you use the same share quantity for all your trades, it may lead to poor outcomes (not looking at how far or close the stop-loss is). 
• Revenge trading practices- Scaling up position size immediately after a loss to take revenge and recoup losses is another common mistake. 
• Not accounting for volatility - Using large sizes in markets that are highly volatile is another error that you should avoid. 

Best Practices

• 1:2 thumb rule - Do not risk more than 1-2% of your total capital on one trade. 
• Calculate based on the stop-loss - Always size your position so that, if your stop-loss is hit, you will only lose the pre-fixed 1-2%. 
• Lower the size in highly volatile markets - If the stop-loss needs to be wider due to market volatility, reduce the share quantity. This will help you keep the cash risk more consistent. 

Make sure you do not move or extend the stop-loss to avoid sudden losses, as it may convert smaller losses into bigger ones. Don’t change your strategies impulsively and focus more on managing risks consistently. Have a trading plan in place that is emotion-free and not driven by impulse, and always account for slippage, commissions, and swap fees (particularly for high-frequency trading).
