1. What is a Price Impact Calculator for Forex?

Definition: This calculator measures how much a trade affects the market price in the Forex market.

Purpose: It helps traders understand the market impact of their trades and manage execution costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( PI \) — Price Impact (USD per pip)
• \( \Delta P \) — Price change caused by the trade (USD)
• \( V \) — Volume traded (in standard lots)

Explanation: The price change is divided by trade volume to determine the impact per pip.
