RISK-TO-REWARD RATIO IN A PROP CHALLENGE: WHAT TARGETS ACTUALLY WORK
Risk-to-Reward Ratio in a Prop Challenge: What Targets Actually Work
Risk-to-Reward Ratio (R:R) is one of the fundamental metrics in trading, but in practice, it is often used too mechanically.
For example, a trader may decide in advance to take only trades with an R:R of at least 1:2, without considering market structure or where the realistic price target actually is.
On a prop Challenge, there are two additional factors to consider: drawdown limits and the profit target.
That is why it is important not just to look for the highest possible R:R, but to understand how much you are risking on each trade, how realistic the target is, and how a potential loss will affect your remaining buffer before reaching the limits.
In this article, we'll break down how to calculate R:R during a prop Challenge, how to choose realistic targets, and why the "only trade setups with at least 1:2" rule does not work in every situation.

What Does the Risk-to-Reward Ratio Show?
The Risk-to-Reward Ratio (R:R) shows how much a trader is willing to lose on a trade relative to the potential profit.
For example, with an R:R of 1:2, the potential profit is twice the amount at risk. If the trader stands to lose $500 if the Stop Loss is triggered, the potential profit should be $1,000.
With an R:R of 1:3 and the same $500 risk, the potential target would be $1,500.
R:R is directly related to win rate. The higher the potential profit relative to risk, the lower the win rate required to break even.
R:R
Minimum Win Rate to Break Even
1:1
50%
1:1.5
40%
1:2
33.3%
1:3
25%
For example, with an R:R of 1:3, a strategy theoretically breaks even with a win rate of just 25%. With an R:R of 1:1, it requires a 50% win rate.
However, this is a mathematical model that does not account for commissions, slippage, or other trading costs. The stated R:R also says nothing about how often price actually reaches the Take Profit.
That is why a high R:R does not automatically make a trade better. If the chart provides a realistic target of only 1:1.5, setting the Take Profit at 1:3 just to achieve a more attractive ratio may simply reduce the probability of reaching it.
On a prop Challenge, daily and total drawdown limits as well as the profit target also come into play. Therefore, R:R should be considered together with the probability of reaching the target, risk per trade, and the remaining buffer before the limits, rather than as an isolated number.
Why the "Always Trade at Least 1:2" Rule Doesn't Work
The rule of taking only trades with an R:R of at least 1:2 makes sense mathematically, but it ignores the most important factor – actual market structure.
The Take Profit should be determined not by the desired risk-to-reward ratio, but by the level that price has a reasonable chance of reaching.
Imagine that the nearest significant resistance level corresponds to an R:R of 1:1.5. If you set the Take Profit at 1:2 just to follow the rule, the market will not move further simply because you want it to. Price may reach resistance, reverse, and eventually stop out the position.
In this situation, the problem is not the 1:1.5 R:R. The problem is that the 1:2 target did not align with market structure.
The logic should therefore work in reverse: first, the trader identifies a potential target on the chart, then calculates the resulting R:R and determines whether the trade fits their trading system.
If a structurally justified target gives an R:R of 1:1.5, that does not automatically make the trade bad. It should be evaluated together with the probability of the setup playing out, Stop Loss placement, and the strategy's historical statistics.
How to Choose Targets Based on Market Structure
The market itself provides reference points for Take Profit placement. Traders can use the same structural elements that help identify entries.
Swing Highs and Swing Lows
One of the clearest reference points is previous significant highs and lows.
For a long position, the nearest swing high can serve as a potential target; for a short position, the nearest swing low. Price has reacted in these areas before, and liquidity may be located beyond these extremes.
For example, if a long position is opened from an order block with the Stop Loss below it, the nearest significant swing high can be considered the first potential target.
If that high is also connected to a previous Break of Structure, the level gains additional structural significance.
Fair Value Gaps
FVGs can also be used as intermediate profit-taking targets.
For example, if an FVG is located above a long entry while the next structural target is even higher, the trader can consider taking partial profit around the FVG and leaving the remaining portion of the position open until the next significant level.
This approach allows the trader to manage the trade as price moves rather than choosing between closing the entire position or waiting for a distant target.
Liquidity Pools
Areas where liquidity is concentrated can also serve as potential targets: equal highs and lows, previous swing points, and other visible levels.
For a long position, potential liquidity above the current price can serve as a target reference. For a short position, the logic is reversed – attention shifts to liquidity below the current price.
This concept is connected to liquidity grabs. For example, after liquidity below the lows has been swept and an upward move is confirmed, the next liquidity area above price may become one of the potential targets.
The main principle remains the same: first identify a logical target on the chart, then calculate the trade's R:R.
The Take Profit should not be moved to an arbitrary level just to achieve an attractive 1:2 or 1:3 ratio.
How R:R Relates to the Challenge Profit Target
A Challenge profit target can be broken down into a series of individual trades in advance. To do this, you need three metrics: risk per trade, average R:R, and the strategy's win rate.
This provides a rough estimate of how many trades may be needed to reach the target while following the existing trading system.
How Many Trades Does It Take to Reach the Target?
Suppose the profit target is 10%, risk per trade is 0.75%, and the average R:R is 1:2.
With these parameters:
A winning trade generates 1.5%
A losing trade costs 0.75%
With a 50% win rate, the average mathematical expectancy is 0.375% per trade
Reaching 10% would require approximately 27 trades on average
This does not mean the target will be reached exactly on the 27th trade. Winning and losing trades can occur in different sequences, so the actual result will vary.
However, this calculation highlights an important point: you do not necessarily need to complete the Challenge target with just a few large trades. If the strategy has positive expectancy, progress can be made gradually while maintaining consistent risk and following the trading plan.
Hash Hedge has no maximum time limit for completing a Challenge, so traders are not constrained by a strict deadline and can wait for suitable setups.
Partial Profit-Taking and the Actual R:R
R:R does not necessarily remain unchanged until a trade is fully closed. A trader can close portions of a position as price reaches predefined levels.
For example, the initial target may be 1:3, but there may be several significant structural levels along the way. Instead of waiting for one final target, part of the position can be closed earlier.
It is important to understand that partial profit-taking changes the final R:R of the entire trade. If half of the position is closed at 1:1 and the other half reaches 1:3, the final result will be lower than if the entire position had been closed at 1:3.
Therefore, traders should evaluate the actual average risk-to-reward ratio across completed trades rather than only the initial R:R shown on the chart.
Taking Partial Profit at 1:1
One way to manage a position is to close part of it after price has moved a distance equal to the initial risk.
For example, when price reaches 1:1, the trader closes 50% of the position. The remaining portion stays open until the next structural target.
The Stop Loss on the remaining position can then be moved closer to the entry point if this is part of the trading system and is supported by market structure.
This approach allows the trader to lock in part of the profit while maintaining exposure to further price movement.
However, there is a trade-off. If price moves directly to the more distant target, the final profit will be lower than if the entire position had been held until Take Profit.
Therefore, partial profit-taking is not automatically a more profitable strategy. Its effectiveness depends on the statistics of the specific trading system.
Scaling Out of a Position
If the potential move offers an R:R of 1:3 or higher, the position can be divided into several parts.
For example:
1
First portion at 1:1.
Part of the position is closed to lock in the first profit.
2
Second portion at 1:2.
Another part is closed if the move continues.
3
Third portion at the structural target.
The remaining position is held until a swing high, liquidity zone, or another predefined level.
This way, the trader does not depend on a single exit point and can gradually lock in profits as the move develops.
However, the levels and size of each partial exit should ideally be determined before entering the trade.
Constantly changing Take Profit levels after entry based on the current P&L can quickly turn a predefined R:R setup into emotional position management.
On a prop Challenge, this is particularly important: the goal is not to squeeze the maximum possible profit out of every individual trade, but to maintain controlled risk and consistently progress toward the profit target.
Common R:R Mistakes During a Prop Challenge
The Target Is Beyond Several Strong Levels
If price needs to move through several significant support or resistance levels to reach a 1:3 R:R, the target may be too optimistic.
For example, a trader opens a long position with a 1:3 target, but strong resistance is already located at the 1:1.5 level. Price may reach it, reverse, and eventually stop out the position without ever reaching the original Take Profit.
That is why it is better to determine the target based on the nearest significant structural level rather than forcing it to fit a predefined R:R.
If market structure provides 1:1.5, that is the ratio that should be evaluated when deciding whether to take the trade. If the trading system requires a minimum of 1:3, it may be better to wait for another setup where the structural target is genuinely far enough away.
Widening the Stop Loss After Entry
Another common mistake is moving the Stop Loss farther away from the entry when price begins moving against the position.
For example, a trade is initially planned with an R:R of 1:2. After entering, however, the trader widens the Stop Loss to give price "more room." The potential loss increases, and the original risk calculation no longer applies.
The Stop Loss should ideally be determined before opening the position based on market structure. Its distance from the entry is then used when calculating position size.
If the level that invalidates the trade setup is broken after entry, moving the Stop Loss farther away does not make the original idea stronger. It only increases the potential loss.
Focusing Only on Potential Profit
A high R:R may look attractive, but a large potential profit should not become a reason to increase risk.
For example, with 0.75% risk, a trade with an R:R of 1:3 can potentially generate 2.25%. But if the Stop Loss is triggered, the trader still loses the predefined 0.75%.
Before entering, it is therefore important to evaluate not only the potential profit but also the size of the potential loss and the remaining buffer before the daily and total drawdown limits.
Ignoring the Consistency Rule
Some prop firms have a consistency rule that limits the percentage of total profit that can be generated from a single trade or trading day.
Therefore, a large profit from a high-R:R trade may affect whether the conditions of a particular Challenge are met.
For example, with 0.75% risk, a trade with an R:R of 1:4 can potentially generate 3%. If the prop firm has a consistency rule, such a result may represent too large a share of the total profit and require the trader to account for additional restrictions.
At Hash Hedge, the consistency rule does not apply at all – neither during the Challenge nor on the Funded Account. Therefore, a large profit on a single trading day does not violate the rules.
However, the absence of a consistency rule does not eliminate the need for risk management. A high R:R should not be used as a reason to increase position size or exceed the predefined amount of risk.
Key Takeaways
1
R:R shows the relationship between potential loss and potential profit.
However, the Take Profit should be based on market structure rather than adjusted to fit a desired ratio.
2
A realistic target matters more than an attractive R:R.
A structurally justified 1:1.5 target may make more sense than 1:2 or 1:3 if price would need to move through several strong levels to reach them.
3
R:R should be evaluated together with win rate.
The higher the average profit relative to the average loss, the lower the win rate required to break even. But this only works if the stated targets are actually reached in practice.
4
The Challenge target can be broken down into a series of trades.
Calculating based on risk, average R:R, and win rate can help estimate the number of trades required and avoid trying to pass the Challenge with a few aggressive entries.
5
Partial profit-taking changes the final R:R.
Closing part of a position allows the trader to lock in profit earlier, but it also reduces potential profit if price subsequently reaches the more distant target.
6
The Stop Loss is determined before entry.
Its placement should depend on market structure and the level at which the trade setup becomes invalid. If the Stop Loss is wide, the position size should be adjusted – not the acceptable level of risk.
7
During a prop Challenge, R:R should be considered together with drawdown limits.
Potential profit matters, but it is even more important to understand the potential loss in advance and how it affects the remaining account buffer.
8
The consistency rule depends on the specific prop firm's conditions.
With a high R:R, a single winning trade can account for a significant share of the total result, which matters if the firm has a consistency rule. Hash Hedge has no consistency rule during either the Challenge or the Funded Account stage.
