Python Developer for TradingView Webhook to Multi-Broker Order Routing System

We are Looking for Freelance Full Stack Python Developer

Job Title: Python Developer for TradingView Webhook to Multi-Broker Order Routing System

Project Type: Freelance

Project Overview

We need an experienced Python developer to build a webhook-based order routing system that:

• Receives real-time trading signals from TradingView alerts (Pine Script indicators)
• Routes orders to multiple Indian broker accounts (Zerodha, Upstox, Angel One, Fyers, etc.)
• Manages individual static IP addresses per broker for NSE algo trading compliance
• Operates via a web-based backend with reliable execution at market hours (9:15 AM onwards)

Core Requirements

Technical Skills (Mandatory)

Python Backend Development:

• Flask or FastAPI for webhook endpoint creation
• Experience handling HTTP POST requests and JSON payloads
• Asynchronous processing for low-latency order placement

Indian Broker API Integration:

• Hands-on experience with at least 2 of these: Zerodha Kite Connect, Upstox API, Angel One SmartAPI, Fyers API
• Understanding of OAuth2/token-based authentication
• Order placement, modification, and cancellation logic
• Error handling for API rate limits and broker-specific responses

TradingView Webhook Knowledge:

• Parsing TradingView alert messages ({{strategy.order.action}}, {{ticker}}, {{close}}, etc.)
• Validating and mapping signals to broker-specific formats
• Experience with Pine Script alerts is a plus

Infrastructure & Deployment:

• VPS/cloud server setup (AWS, DigitalOcean, Vultr) with static IP configuration
• Multi-broker IP isolation (Docker containers or proxy routing preferred)
• Deployment near Mumbai/NSE for low latency
• Linux server administration basics

Nice to Have

• Experience with Indian stock/options trading workflows (Nifty, Bank Nifty, Sensex)
• Knowledge of NSE algo trading compliance (static IP whitelisting)
• Database management (SQLite/Redis) for logging and state management
• Real-time monitoring/alerting setup (Telegram bot, email notifications)
• Prior work on algo trading systems or HFT execution platforms

Scope of Work

Phase 1: Core Development

• Build Flask/FastAPI webhook receiver to accept TradingView alerts
• Implement authentication and security (HTTPS, API key validation)
• Integrate 3-4 Indian broker APIs with order placement logic
• Create routing logic to send orders to specific brokers based on configuration (JSON/YAML file)
• Add basic error handling, logging, and retry mechanism

Phase 2: Infrastructure Setup

• Deploy backend on VPS with static IP per broker account
• Configure IP whitelisting with brokers' API portals
• Set up Docker containers or proxy routing for multi-broker IP isolation
• Test order execution across all brokers during market hours

Phase 3: Testing & Documentation

• End-to-end testing with live TradingView alerts (paper trading first)
• Validate order placement speed (target: <500ms from signal to broker)
• Provide complete documentation:
• Setup instructions (server, broker API keys, TradingView webhook config)
• Code comments and architecture overview
• Troubleshooting guide for common errors
• Handover with 7-day post-launch support for bug fixes

Deliverables

• Fully functional Python backend (source code via GitHub/GitLab)
• Deployed system on VPS with static IP configuration
• Integration with 3-4 Indian brokers (client will provide API credentials)
• TradingView webhook setup guide (alert template, URL endpoint)
• Documentation (README, architecture diagram, API reference)
• 7 days of support after go-live for troubleshooting

Project Timeline

• Week 1: Core webhook + single broker integration
• Week 2: Multi-broker routing + IP setup
• Week 3: Testing, documentation, and deployment
• Total Duration: 3-4 weeks (flexible based on complexity)

How to Apply

Please include in your proposal:

• Experience:
• Links to GitHub repos/projects involving TradingView webhooks or broker API integrations
• Specific Indian brokers you've worked with (Zerodha, Upstox, etc.)
• Any prior algo trading or HFT system development
• Technical Approach:
• Brief outline of your proposed architecture (webhook receiver → order routing → broker APIs)
• How you'll handle static IP per broker (Docker/proxy/VPS strategy)
• Tools/frameworks you'll use (Flask vs FastAPI, hosting provider, etc.)
• Questions:
• Ask any clarifying questions about broker count, order types (market/limit/SL), or expected signal volume
• Timeline & Budget:
• Your estimated hours and rate
• Availability to work during Indian market hours (9:15 AM - 3:30 PM IST) for testing

Important Notes

• No upfront API credentials: We'll provide broker API keys after contract signing with NDA
• Security is critical: All API keys, tokens, and credentials must be stored securely (environment variables, not hardcoded)
• Market hours testing required: You must be available for at least 2-3 live market sessions for validation
