How does a Position Size Calculator work?

 

A Position Size Calculator is a trading tool that helps determine the appropriate amount of currency units to buy or sell based on the risk level a trader is willing to accept for each trade. It works by incorporating several key inputs: the trader’s account equity (total value of the trading account), the risk percentage (the fraction of account equity the trader is willing to risk), the stop loss in pips (the number of pips the trader is willing to lose before exiting a trade), and the currency pair being traded.

 

The Forex calculator uses these inputs to compute the risk in monetary terms (Risk Amount = Trading Account Equity * Risk Percentage). It then calculates the value of a pip for the specific currency pair (Pip Value = Pip Size * Contract Size) and, finally, determines the ideal position size. The position size is calculated by dividing the monetary risk amount by the product of the number of pips at risk and the pip value (Position Size in Lots = Risk Amount / (Stop Loss in pips * Pip Value)). This calculation ensures that the trader only risks the specified percentage of their account on a single trade, aligning with their overall risk management strategy.

 

In the next part, we will explain several values that help you correctly set your position size calculator:

 

1. Trading Instrument:

●       This is the financial asset you intend to trade, such as EURUSD, XAUUSD (Gold), or US30 (Dow Jones 30).

●       How to Use It: Select your desired trading instrument from the list provided by your broker. This choice determines factors like pip size and contract size.

 

2. Trading Account Currency:

●       This is the currency in which your trading account is denominated, typically USD, EUR, etc.

●       How to Use It: Ensure you know the currency of your account as it affects the calculation of pip value and your risk in monetary terms.

 

3. Trading Account Equity:

●       This represents the total value of your trading account.

●       How to Use It: Input the current value of your trading account.

 

4. Risk Percentage:

●       This is the percentage of your trading account equity that you're willing to risk on a single trade.

●       How to Use It: Decide how much of your account you will risk (commonly between 1% to 3%).

 

5. Stop Loss (in pips):

●       It represents the number of pips you will lose on a trade before automatically closing.

●       How to Use It: Determine how many pips away from your entry point your stop loss will be set.

 

6. Pip Size:

●       It represents the value of a single pip movement for the trading instrument.

●       How to Use It: Your broker typically gives this value. For EURUSD, it's often 0.0001, while for XAUUSD, it's 0.1.

 

7. Contract Size (units per lot):

●       This is the number of units of the trading instrument in one standard lot.

●       How to Use It: This information can be found in your MT4/MT5 platform under Symbol Specification. For EURUSD, it's usually 100,000 units, while for XAUUSD, it's 100 ounces.

 

Position Size Calculator Examples and Formulas:

In this part, we will discover a range of simple yet efficient formulas and examples related to the Position Size Calculator. These are designed to provide a clear understanding of how to apply these formulas in real-world trading scenarios. Whether a novice or professional, you can enhance your ability to calculate position sizes accurately, ensuring better risk management and trading efficiency.

 

Risk Amount = Trading Account Equity * Risk Percentage

Pip Value for a Standard Lot = EURUSD Pip Size * Contract size (units per lot)

Position Size in Lots = Risk Amount / (Stop Loss (pips) * Pip Value for a Standard Lot)

Position Size in Units = Position Size in Lots x Contract Size (units per lot)

 

EURUSD Example:

●       Trading Account Equity: $10,000

●       Risk Percentage: 2%

●       Stop Loss: 50 pips

●       Pip Size: 0.0001

●       Contract Size: 100,000 units

●       Calculation:

●       Risk Amount = $10,000 * 2% = $200

●       Pip Value for a Standard Lot = 0.0001 * 100,000 = $10

●       Position Size in Lots = $200 / (50 * $10) = 0.4 lots

●       Position Size in Units = 0.4 * 100,000 = 40,000 Units

 

XAUUSD (Gold) Example:

●       Trading Account Equity: $10,000

●       Risk Percentage: 2%

●       Stop Loss: 50 pips

●       Pip Size: 0.1

●       Contract Size: 100 ounces

●       Calculation:

●       Risk Amount = $10,000 * 2% = $200

●       Pip Value for a Standard Lot = 0.1 * 100 = $10

●       Position Size in Lots = $200 / (50 * $10) = 0.4 lots

●       Position Size in Units = 0.4 * 100 = 40 Ounces/Units

 

US30 (Dow Jones 30) Example:

●       Trading Account Equity: $10,000

●       Risk Percentage: 2%

●       Stop Loss: 50 pips

●       Pip Size: 0.1

●       Contract Size: 10 units

●       Calculation:

●       Risk Amount = $10,000 * 2% = $200

●       Pip Value for a Standard Lot = 0.1 * 10 = $1

●       Position Size in Lots = $200 / (50 * $1) = 4 lots

●       Position Size in Units = 4 * 10 = 40 Units
