Formula Used in Lot Size Calculation

1. Risk Amount Formula
\text{Risk Amount} = \frac{\text{Account Balance} \times \text{Risk %}}{100}
Explanation:
This determines how much money you are willing to lose on one trade.
2. Stop Loss Value Formula
Stop Loss Value=Stop Loss (pips)×Pip Value
Explanation:
This shows how much loss you will face if stop loss is hit.
3. Lot Size Formula
Lot Size=Stop Loss ValueRisk Amount
Explanation:
This determines the correct trade volume based on your risk.
4. Profit Estimation Formula
Profit Potential=Risk Amount×2
Explanation:
This assumes a 1:2 risk-to-reward ratio (common in trading).
Example Calculation
Let’s understand with a real trading example:
- Account Balance = $1000
- Risk = 2%
- Stop Loss = 30 pips
- Pip Value = $10
Step-by-Step Calculation
1. Risk Amount
2% of $1000 = $20
2. Stop Loss Value
30 pips × $10 = $300
3. Lot Size
20 ÷ 300 = 0.066 lots
4. Profit Potential
20 × 2 = $40
