Run reliably on a VPS server Preferred Technical Stack (flexible): Python Node.js Experience working with brokerage APIs Experience with automated trading systems Important Features: Must support multi-leg option spreads (not single-leg only) Replicate trades quickly after the master account order is placed preferable via webhook or order event stream Basic error handling if an order fails Simple configuration file for account IDs and sizing rules Nice to Have: Prior experience with the Tradier API Experience building trade copiers Knowledge of options trading structures Deliverables: Fully working trade copier Installation instructions Basic documentation Ability to run on a VPS server Accounts: 1 master account Up to 6 follower accounts Usage: The system will mainly copy options credit spreads placed manually in the master account.
