I'm seeking an expert developer to create a comprehensive, automatic trade execution-focused web application for algorithmic trading. The application needs to allow me to manage everything related to trading, including backtesting and integrating with multiple brokers. I have two sample website,
https://algotest.in/,
https://web.algorooms.com/
which has similar functionalities to what I need.

Key Features:
- Automatic Trade Execution: This is the primary focus of the project. The application should be capable of executing trades automatically based on pre-defined parameters or strategies.
- Broker Integration: The application needs to integrate with several top brokers in India, including Zerodha and Angelone. Knowledge of these platforms and their APIs would be a significant advantage.
- Custom Strategy Creation: While I'm unable to share my specific trading strategies, I want to be able to create my own within the application. Thus, the application should support a flexible and user-friendly interface for strategy input.

Ideal Skills and Experience:
- Extensive experience in developing web applications, preferably for trading.
- Strong understanding of algorithmic trading and its principles.
- Familiarity with Indian trading platforms and brokers.
- Ability to create an intuitive user interface for strategy creation.
- Excellent problem-solving skills and attention to detail.
