1. What is a Trading Profit and Loss Calculator?

Definition: This calculator determines the profit or loss from a trading position based on price changes, trade volume, and associated costs.

Purpose: It helps traders evaluate the financial outcome of their trades by accounting for all relevant factors.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Profit or loss (USD)
• \( P_{new} \) — New price (USD)
• \( P_{old} \) — Old price (USD)
• \( V \) — Volume (lots)
• \( C \) — Costs (USD)

Explanation: The price difference is multiplied by volume to get gross profit/loss, then costs are subtracted to determine net result.

3. Importance of Profit/Loss Calculation

Details: Accurate profit/loss calculations are essential for trade evaluation, risk management, and performance tracking.

4. Using the Calculator

Tips: Enter the entry and exit prices, trade volume, and any associated costs (commissions, fees). Volume must be > 0.

Q4: Can I use this for any asset class?
