Strategy standardization entails the development of take-profit and stop-loss setups, the generation of signal alerts, and the implementation of a backtesting framework, all serving to provide an operational environment and safeguard for trading strategies. Bullets represent the generation of entry and exit points in trading strategies, while guns include the creation of profit and loss limits and signal alerts, with the battlefield representing the trading platform. Modular design enhances the system's flexibility, scalability, maintainability, and adaptability. The buy-sell point algorithm (bullets) is like a public key, while profit and loss limits and backtesting framework (guns) are like a private key, working together to form a complete trading system. The benefits of this design include security, flexibility, reusability, and maintainability. The modular trading system design is analogous to public key encryption and private key decryption in encrypted communication. This design improves the system's security, flexibility, reusability, and maintainability
