🌸 Flower Exchange Project

The Flower Exchange Project is a trading platform for buying and selling flowers, built as part of the LSEG C++ Workshop Series. It includes a C++ back-end for processing orders and a React-based front-end for generating orders in CSV format.

Getting Started

1. Clone the repository to your local machine:

git clone <repository_url> 

2. Run the Trader and Exchange applications to simulate placing and matching orders.

Input and Output

• Input: Orders are submitted in CSV format (orders.csv) containing fields like Order ID, Client Order ID, Instrument, Side (Buy/Sell), Quantity, and Price.
• Output: The execution_rep.csv file is generated, which shows the status of each order (e.g., New, Partial Fill, Fill, Reject).

⚙️ Implementation Details

• Order validation checks for missing fields, valid flower types, side (buy/sell), valid quantities, and prices. Rejected orders are noted with reasons.
• Orders are sorted and matched based on price and quantity. The system supports full and partial executions of orders.
• An optimized version is available for handling single flower type orders, reducing computation overhead for better performance.
• The execution time is logged in the output for performance analysis.

React Front-End

A separate front-end interface is built using React to allow users (traders) to submit buy and sell orders. The front-end generates the orders.csv file, which is then processed by the Exchange Application.

📋 Instructions to Run the React App

1. Clone the front-end repository:

git clone <repository_url>

2. Navigate to the project directory:

cd <project_directory>

3. Install the dependencies:

npm install

4. Start the React development server:

npm start

5. Open your browser and navigate to http://localhost:3000 to access the Trader Application.
6. Submit orders through the interface, and the orders.csv file will be generated automatically.
