Trading Backend

This is a simple trading bot application built with Rust that monitors stock price changes using a mock API. Implements basic trading strategies to buy or sell stocks based on price movements.

Getting Started

Prerequisites

• Rust and Cargo installed on your machine. You can install them from rustup.rs.

Clone the Repository

git clone https://github.com/pakhare/backend-rust-algo.git
cd backend-rust-algo

Start the mock API server:

cargo run --bin mock_api

This will start the mock API server at http://localhost:8080/api/stock_prices

Build and Run the Trading Bot

In a new terminal window, navigate to the root of the project and run:

cargo run --bin backend_assignment

The trading bot will start monitoring stock prices and executing trades based on the defined strategy.

API Usage

The mock API provides an endpoint to retrieve stock prices:

Endpoint: GET /api/stock_prices
Response:

[
    {
        "id": 1,
        "symbol": "AAPL",
        "price": 150.0,
        "quantity": 10
    },
    {
        "id": 2,
        "symbol": "GOOGL",
        "price": 2800.0,
        "quantity": 5
    }
]

Trading Logic

The trading bot evaluates trades based on the following criteria:

• Buy: When the stock price drops by 2% compared to the last price, and there are no open positions.
• Sell: When the stock price rises by 3% compared to the last price, and there is an open position.
• Profit/Loss Tracking
  • Current Position: Positive for long positions, negative for short positions.
  • Current Balance: The cash balance available for trading.
  • Total Profit: The overall profit/loss based on current positions and balance.

Technologies Used and Dependancies

• Rust
• Actix Web (for the mock API)
• Reqwest (for making HTTP requests)
• Serde (for JSON serialization/deserialization)
• Tokio (for asynchronous programming)
