four different statistics commonly used in the forex (foreign exchange) market:

1. **Exchange Rate**: This is the value of one currency in terms of another. It tells you how much one currency can be exchanged for another. For example, the EUR/USD exchange rate of 1.20 means one Euro can be exchanged for 1.20 US Dollars.

2. **Volatility**: Volatility measures the degree of variation in the exchange rate of a currency pair over time. Higher volatility implies greater price fluctuations and potential trading opportunities but also higher risk.

3. **Trading Volume**: Trading volume indicates the total number of currency units traded in a given time frame. Higher trading volumes can indicate increased liquidity and potentially tighter spreads in the forex market.

4. **Pip (Percentage in Point)**: A pip is the smallest price movement that a given exchange rate can make based on market convention. It's usually the last decimal place of a currency pair's quote. For example, if EUR/USD moves from 1.2000 to 1.2001, it has moved one pip.

These statistics are essential for traders and investors to make informed decisions in the forex market.
