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.

I have extensive experience developing trade copiers and trading infrastructure for MetaTrader. I haven't yet worked directly with the Rithmic API, but I can quickly learn new trading APIs and would be happy to start with an architecture review and Phase 1 implementation.

Hi there, I’ve developed trade copiers, multi-account trading systems, and broker API integrations with a focus on low-latency execution and reliability. I can review your existing Propcopia dashboard, optimize the architecture, and build a production-ready Rithmic trade copier with scalable support for Tradovate and NinjaTrader. Portfolio: https://www.freelancer.com/u/MqlcoderHub?frm=MqlcoderHub&sb=t I’m available to start immediately and would be happy to discuss the architecture. Best, Fasih

Hi, I like this project because trade copiers are one of those things that seem simple right up until three accounts decide they interpreted "Buy 2 contracts" differently. Then it gets exciting. ? I've worked extensively with trading APIs, algorithmic trading systems, risk management, and low-latency applications. My first priority wouldn't be adding features—it would be making sure the foundation is boring, reliable, and impossible to accidentally blow up funded accounts with. For Phase 1, I'd start by reviewing the existing Propcopia dashboard and proposing a clean architecture around: * Rithmic trade replication. * Account mapping and position synchronization. * Risk controls (kill switches, position limits, daily loss limits, etc.). * Low-latency order routing and execution handling. * Logging, monitoring, and failure recovery mechanisms. I'd also recommend designing the broker layer as a plugin-based architecture from day one. That way, when Tradovate and NinjaTrader join the party, we're adding adapters—not rebuilding the house because someone bought new furniture. Looking forward to learning more about Propcopia and helping build something that's production-grade rather than "works great unless the market opens." ? Best, Rawan P.S. In trading infrastructure, boring is beautiful. If nobody notices the copier exists, we've done our job perfectly.

Hi, Drop me a message — I'll share a quick prototype based on what I understood. If it matches your expectations, we can move forward. Thanks!

Hi, this is exactly the kind of work where a clean architecture matters from day one: a real-time futures trade copier with Rithmic first, then Tradovate and NinjaTrader later. I’ve built systems where order routing, account mapping, and execution reliability had to be handled carefully, especially around low latency and risk controls. I’d start by reviewing the existing Propcopia dashboard, identifying what can be reused, and separating UI, execution, and broker integration into clear modules. From there, I’d implement the Rithmic phase with solid trade replication, kill switch logic, position limits, and documented deployment steps. The code would be structured to support future broker integrations without a rewrite. If you want, I can help turn the prototype into a production-ready copier. Best regards, Gabriel

Hello, your phased approach is exactly how I'd tackle a production trading system. I can review the existing codebase, identify architectural improvements, and develop a robust Rithmic integration with low-latency trade replication and built-in safety features like kill switches and position limits. I look forward to discussing your current implementation and deployment strategy.

Hi, integrating real-time trade replication across platforms like Rithmic and Tradovate often hinges on handling the nuances of each API's event-driven architecture. I'd start by ensuring the FIX API is optimized for low-latency execution. Could you share access to your current Propcopia setup so I can assess the integration points?

Hi! Building order routing and account mapping logic with kill switches and position limits is exactly the kind of trading infra I work on. Haven't touched Rithmic's API specifically yet but broker REST/websocket integrations are familiar ground, happy to start there and add Tradovate/NinjaTrader once access opens up. Is the Propcopia dashboard on Python or Node, and do you already have Rithmic sandbox credentials?
