# Estimated trading volume

The Estimated trading volume chart shows roughly how much [USDT](https://docs.p2pprice.app/glossary/) was traded on a chosen [CEX](https://docs.p2pprice.app/glossary/) over time. It helps you see how active the market is for your selected currency.

## What the chart shows

The chart has two lines:

- **Green line**: estimated amount of USDT bought
- **Red line**: estimated amount of USDT sold

Both lines move over time. A higher point on the chart means more trading activity at that moment.

## This is an estimate

The numbers are not exact. They give a general picture of market activity, not a precise count of every trade. Use this chart to spot trends, not to get exact totals.

## How the filters affect the chart

The chart follows three filters:

- **Time range**: how far back you look
- **Currency**: the [fiat](https://docs.p2pprice.app/glossary/) currency you are watching, such as SAR or EGP
- **CEX**: the centralized exchange you selected, for example Binance

When you change any of these filters, the chart updates to match your new selection.

## How to read it

- A **busier market** shows higher lines
- A **quiet market** shows lower, flatter lines
- When the green line is higher than the red line, more USDT was being bought than sold
- When the red line is higher, more USDT was being sold than bought
