The financial report released by EBC Financial Group in 2025 pointed out that 83% of margin calls were due to the imbalance between Risk and return set by traders, and errors in manual calculations by traders led to a reduction in actual profits by as much as 37%¹.

1. Why does a precise and professional risk-reward ratio (RR) determine the fate of your trading account?
"Good traders focus on profitability, while top traders concentrate on the risk-reward ratio" - Statistics of One Million Myfxbook Accounts in 2025 [²]
1.1 Basic Concept: Understand in 2 Minutes What is Risk-Reward Ratio (RR)
Calculation formula: Risk-reward ratio = Your potential profit ÷ Your potential loss.
Let me illustrate and compare for you in a tabular format, and you will understand:
| Parameter | Value | Logic |
|---|---|---|
| Entry Price | 1.1050 | Current EUR/USD |
| Stop-Loss | 1.1020 | Risk: 30 pips |
| Take-Profit | 1.1140 | Reward: 90 pips |
| Actual RR | 1 : 3 | 90 ÷ 30 = 3 |
📊 This is the truth of trading, which is very simple, intuitive, and clear at a glance: even when the win rate is only 40%, a strategy with RR=1:3 can still be profitable. (Data source: Myfxbook 2025 win rate model [³])
Suppose you have made 10 trades, with a profit of $30 per trade and a loss of $10 per trade. Out of the 10 trades, 4 have resulted in losses, totaling $40, and 6 have been profitable, totaling $180.
By subtracting the $40 loss from the $180 profit, you can still earn a net profit of $140. That is to say:
Win rate 40% + RR=1:3 → Expected return = (0.4×3) - (0.6×1) = +0.6 (only counting profits);
Win rate 60% + RR=1:1 → Expected return = (0.6×1) - (0.4×1) = +0.2 (only counting profits);
1.2 Trader's Golden Rule: RR≥1:3 is your bottom line! In 2025, Myfxbook's analysis of stable profitable trading accounts revealed a shocking truth[²]:
| RR Ratio | % of Profitable Accounts | Avg. Annual Return | Max Drawdown |
|---|---|---|---|
| < 1: 2 | 8 % | -15 % | ≥ 50 % |
| ≥ 1 : 3 | 91 % | +34 % | ≤ 25 % |
Now, it's time to seriously consider your RR ratio!
II. Operation Guide for Foreign Exchange Risk-Reward Ratio Calculator: Avoiding the Fatal Mistakes Often Made by 90% of Traders
💡>>> Risk Reward Ratio calculator:
2.1 Choose whether you are going long or short, and then enter three numbers (with screenshot guidance)
Step 1: Choose whether to go long or go short
Step 2: Enter the price:
Entry Price: Current market price or planned listing price (enter your entry price here);
Stop Loss: It must be based on support/resistance levels (or analyzed using a Fibonacci calculator, if applicable);
Take Profit: It must be calculated based on the ratio of RR to 1:3. If you are unsure about this value, input it first, click Calculate, check the calculation result, and then fine-tune this value.
Step 3: Obtain your calculation results
| Output | Meaning | Action |
|---|---|---|
| RR Ratio | Reward ÷ Risk | < 1 : 2 → skip trade |
| Potential Loss (pips) | Loss at SL | Must be ≤ 1-2 % of equity |
| Potential Profit (pips) | Gain at TP | Must be ≥ 2× the risk |
2.2 List of Fatal Errors (Statistics of Huge Losses on Real Trading Accounts in 2025)
| Mistake | Damage | Fix | Case |
|---|---|---|---|
| Ignoring spread | Overstates RR by 0.2-0.5 | Auto-deduct spread | John lost $520 after misreading 1:2.3 as 1:3 |
| Using $ instead of pips | 30 % position sizing error | Link to Pip Calculator | [Link] |
| Swap fees ignored | 15 % RR drift on swing trades | Auto-merge Swap Calculator | Gold long over 3 days: -$90 |
| Moving SL emotionally | RR collapses to 1:0.5 | Lock SL after entry | Sarah widened SL from 30 → 80 pips, lost $2 100 |
| Ignoring Leverage | Margin call on 0.5 % move | Link to Margin Calculator | 500× leverage on EUR/JPY → instant wipeout |
III. Tailored Advanced Strategies for You: Building Your Sustainable Profit Trading System with RR Ratio
3.1 Dynamic stop-loss method: increase the RR ratio by 50%
Scenario: Assuming your original strategy involves a fixed 30-pip stop loss with a risk-reward (RR) ratio of 1:2, and you encounter the release of non-farm payroll data while trading EUR/USD, your dynamic optimization would be:
1) Use the Pivot Point Calculator to calculate the key support level[³]
2) Move the stop loss to 15 points below the support level, reducing the stop loss to 15 points
3) By doing so, you can keep the profit limit at 90 points, which is equivalent to increasing your RR to 1:6
⚠️ Risk Warning: The maximum drawdown for the non-farm strategy in 2024 was as high as 42% [⁴]. This plan is only suitable for traders who can withstand significant fluctuations.
3.2 You also need to implement multi-layer risk control: leveraging the synergy of three major computational tools
"RR ratio is the starting point, not the end point" - EBC 2025 Risk Control White Paper [⁵]
Operation path:
1) The RR calculator yields a result of RR=1:3
2) Click here to access the Position Size Calculator
3) Enter "account balance and other numbers, with risk ratio ≤2%"
4) Check the "number of positions"
Continue to use the Stop Loss Calculator to verify whether your stop loss level is reasonable.
IV. Risk Warning for You from This Platform: The Real Reason for 90% of Traders' Failure
4.1 Mandatory Regulatory Disclosure (FINRA Rules)
"Leveraged forex trading may result in a total loss of your principal investment, potentially exceeding the initial margin. According to FINRA data from 2025, 76.5% of retail traders were in a loss position[6].
Leverage restrictions: EU statutory limit ≤ 30 times | US statutory limit ≤ 50 times | Offshore brokers may reach 500 times (high risk!)
4.2 Tool Limitation Statement
1) Black-Swan Event: For instance, in 2024, the Swiss National Bank removed the lower limit for the euro-Swiss franc exchange rate, leading to a single-day fluctuation of over 20%. This rendered Relative Ratio (RR) calculations completely ineffective, and even technical indicators failed to work. Several foreign exchange brokerage trading servers experienced a brief outage[⁷]
