Futures Trade Copier Dev – Rithmic, Tradovate, NinjaTrader

We are building a production-grade futures trade copier that replicates trades across multiple broker accounts in real time. A working prototype dashboard (Propcopia) already exists on Replit, and we need an experienced developer to review it, propose a clean architecture, and deliver a robust, scalable copier starting with the Rithmic API — with Tradovate and NinjaTrader to follow as API access becomes available.

Requirements:
- Proven experience with futures trading APIs (Rithmic required; Tradovate and NinjaTrader a strong plus)
- Ability to review and build on an existing Replit-based dashboard (Python or Node.js stack)
- Strong understanding of order routing, account mapping, and trade replication logic
- Experience implementing risk controls: kill switches, position limits, latency management
- Comfortable working in phases — Rithmic first, additional brokers added incrementally
- Clean, well-documented code suitable for a production trading environment

Deliverables:
- Review of existing Propcopia dashboard and architecture assessment
- Proposed system architecture for the multi-broker trade copier
- Phase 1: Fully functional Rithmic trade copier with account mapping, order handling, and risk controls (kill switch, etc.)
- Phase 2 (subsequent): Integration of Tradovate and NinjaTrader APIs once access is granted
- Clean codebase with documentation and deployment instructions

Work arrangement: This is a fixed-price project broken into milestones, starting with the Rithmic phase. Scope and pricing for later phases will be agreed upon as API access is obtained.

About the project: This is a serious trading tool aimed at prop traders and funded account holders who need reliable, low-latency trade replication across multiple brokerage accounts.
