# Implementation

When a user wants to open an order (buy or sell), they enter the order parameters (order type, token they want to buy and the one he want to sell, desired token price, and amount) and submits the transaction by signing it in the wallet (MetaMask and Wallet Connect are supported).

After the transaction is executed, TheTrade smart-contract system manages the provided assets and creates a position. The position consists of Uniswap v3 concentrated liquidity in the smallest price range. Once the market price goes up or down to the desired price, assets in the liquidity position are swapped and are available for execution of the order. 

Now, any Ethereum account can get the reward by calling the execute function and finalizing the order. The smart contract gets liquidity back from Uniswap and places the desired asset, obtained at the preset price, in the user's wallet.

## 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://thetrade.gitbook.io/thetrade/features/buy-limit-and-take-profit-orders/use-cases/implementation.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.
