# CEX Ads

The CEX Ads page shows live offers from [CEXs](https://docs.p2pprice.app/glossary/) (centralized exchanges, platforms where you trade on a website or app). Each offer appears as its own card. You can filter by platform, sort by different factors, and switch between buying and selling [USDT](https://docs.p2pprice.app/glossary/) (a digital dollar, a stablecoin worth about 1 US dollar).

## What each card shows

Each card is one offer posted by one advertiser. It shows these parts:

- **Advertiser name.** The username of the person or business posting the offer.
- **Verified merchant star.** A star icon next to the name means this advertiser is a [verified merchant](https://docs.p2pprice.app/glossary/) (a trader the exchange has checked and approved). The name also appears in a different color.
- **Price.** How much local currency you pay or receive per USDT.
- **Available USDT.** The total amount of USDT the advertiser has ready to trade right now.
- **Min and max order.** The smallest and largest trade size the advertiser will accept.
- **Payment methods.** Small badges show how you can pay. Up to three badges appear on the card. If the advertiser accepts more methods, a "+N" badge shows how many extra options there are.
- **Monthly orders.** How many trades this advertiser completed in the past month.
- **Finish rate.** The percentage of this advertiser's trades that completed successfully. Shown as a number like "99.1% finish".
- **Last checked.** When the app last fetched this offer from the exchange.

## Controls

### Buy or sell toggle

A toggle at the top lets you switch between two modes:

- **Buy.** You want to buy USDT. You see advertisers who are selling USDT to you.
- **Sell.** You want to sell USDT. You see advertisers who want to buy USDT from you.

### Platform filter

Chips (small clickable buttons) let you pick which CEXs to include. By default, all platforms are selected. Click a chip to remove that platform from the view. Click it again to add it back. A "Reset" button appears whenever you change the defaults, and clicking it returns all filters to their starting state.

If you click off every chip, the page shows a message asking you to select at least one platform.

### View: By CEX or Best price

Two view options change how cards are arranged:

- **By CEX.** Cards are grouped under a heading for each exchange. Good for comparing offers on one platform at a time.
- **Best price.** All offers from all selected platforms are mixed together and ranked. Each card in this view shows a small label naming its exchange. Good for finding the single best offer across all platforms at once.

### Sort

A sort menu lets you order the cards by:

- **Best price.** Lowest price first when buying, highest price first when selling. This is the default.
- **Most orders.** Advertisers with the most monthly trades appear first.
- **Highest finish rate.** Advertisers with the highest completion percentage appear first.
- **Most available.** Advertisers with the most USDT ready to trade appear first.

## Auto-refresh

The page refreshes itself every 60 seconds. You do not need to reload. A small indicator shows when data was last updated, or if a refresh is in progress.

## How to use it

Here is a simple example. Say you want to buy USDT with Saudi riyals at the best price:

1. Set the toggle to **Buy**.
2. Pick your currency (SAR) in the currency tabs at the top.
3. Leave all platform chips selected so you see every exchange.
4. Switch the view to **Best price**.
5. The sort is already on **Best price** by default, so the cheapest offer appears at the top. For example, a Binance advertiser might show 3.75 SAR per USDT.
6. Check the finish rate and monthly orders on the top cards to find a reliable advertiser.
7. The page updates on its own every 60 seconds, so you can watch for better offers without reloading.
