# Platform comparison

The Platform comparison box shows how [CEXs](https://docs.p2pprice.app/glossary/) (centralized exchanges) compare to each other. For your chosen currency, it displays the average [buy price](https://docs.p2pprice.app/glossary/) and [sell price](https://docs.p2pprice.app/glossary/) for every exchange side by side.

## What the box shows

For each exchange, the box shows:

- The average price buyers paid to get [USDT](https://docs.p2pprice.app/glossary/) (a digital dollar worth about 1 US dollar) in your chosen currency.
- The average price sellers received when giving USDT.

Seeing all exchanges together lets you spot which one was cheaper to buy on and which one gave sellers a better return.

## What the box ignores

The box ignores the single-CEX filter on the page.

If you have the rest of the analytics page filtered to show one exchange (for example, Binance), the Platform comparison box still pulls data from all exchanges. It always shows all of them, not just the one you selected.

This is the whole point of the box: comparing exchanges against each other. A single-exchange filter would make that comparison impossible.

## What the box still follows

Even though it ignores the CEX filter, the box does follow two other settings:

- **Currency**: it shows prices only for the currency you have chosen.
- **Time range**: it looks only at data from the time period you have selected.

Change either of those and the box updates right away.

## How a beginner uses it

The Platform comparison box is useful for one simple goal: finding where to get the best price.

- **Buying USDT**: look at the buy prices. The exchange with the lowest number is where buyers paid less on average.
- **Selling USDT**: look at the sell prices. The exchange with the highest number is where sellers got more on average.

Use this to choose the exchange that fits your next trade.
