Project Specifications

You are provided with the implementation of the Trade model. The REST service must expose the /trades endpoint, which allows for managing the collection of trade records in the following way:

POST request to /trades:

• creates a new trade
• expects a JSON trade object without an id property as a body payload. You can assume that the given object is always valid.
• adds the given trade object to the collection of trades and assigns a unique integer id to it. The first created trade must have id 1, the second one 2, and so on.
• the response code is 201, and the response body is the created trade object

GET request to /trades:

• returns a collection of all trades
• the response code is 200, and the response body is an array of all trade objects ordered by their ids in increasing order

GET request to /trades/<id>:

• returns a trade with the given id
• if the matching trade exists, the response code is 200 and the response body is the matching trade object
• if there is no trade with the given id in the collection, the response code is 404 with the body having the text ID not found

DELETE, PUT, PATCH request to /trades/<id>:

• the response code is 405 because the API does not allow deleting or modifying trades for any id value
