# The Buy/Sell/Cart Widget

If you want to either buy or sell digital assets using the power of AlphaDex Limit Orders you can do so via the widget. The widget has three main tabs

* BUY - for placing orders to purchase digital assets
* SELL - for placing orders to sell digital assets
* CART - a place where you can add either buy or sell orders to a shopping cart for submitting later or submitting all at once

## Highest Buy / Sell

The Highest Buy or Sell button is a quick way to add an order at the top of the order book for either the buy or sell side.

## Highest Buy / Sell +1

The Highest Buy or Sell +1 button places your order in front of the current highest buy or lowest sell  price. If a market order was placed your order would be the first to be filled.

## Maker Fee

If you are supplying liquidity to the order book then you will receive a 'Maker Fee'. You will see a negative fee value here, which is normal. This is the Maker Fee that you will earn once your order is filled by another user.<br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.shardspace.app/trading/limit-order-trades/the-limit-order-page/the-buy-sell-cart-widget.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
