Develop 9-EMA VWAP Bot

I need a clean, production-ready Python solution that trades automatically using a simple 9-period EMA + VWAP strategy. The script must:

• Stream live market data, calculate the indicators in real time, and act instantly on the signals it generates.
• Place, modify, and cancel orders through my broker’s REST API without manual intervention.
• Run reliably inside an AWS environment (EC2 or Lambda). Environment variables should hold all keys and secrets, and logging must write to CloudWatch for easy monitoring.

Please structure the code for easy maintenance: clear functions, comments, and a requirements.txt file. Once finished, provide deployment instructions I can copy-paste into a fresh AWS instance and a quick test that confirms the bot is receiving data and submitting orders.

Speed, stability, and readable code are the key acceptance criteria.
