WHAT WE ARE BUILDING: - Dual-mode automated trading bot (scalp trades and swing trades) - Architecture: TradingView (signal generation) > Webhook > VPS middleware server > NinjaTrader 8 (execution) - Two completely independent trader accounts with separate TradingView and NinjaTrader instances routed through one shared middleware server - Three active trading sessions - Economic calendar integration - Full alert system including Telegram bot, push notifications, and SMS with tiered priority levels - Instrument-agnostic architecture built to support additional futures instruments via config - 30-day paper trading phase required before any live deployment REQUIRED SKILLS (NON-NEGOTIABLE): - Pine Script: Expert level - multi-timeframe strategy logic, indicator conditions, webhook alert systems - NinjaScript / C#: Expert level - fully automated execution, order management, position tracking, risk controls - Webhook middleware: Proficient in Node.js or Python server on VPS routing signals between TradingView and NinjaTrader instances - VPS setup and 24/7 deployment - Telegram bot development with interactive alerts and command-response capability - Dual-account architecture with fully siloed accounts, independent risk tracking, alerts and logs STRONGLY PREFERRED: - Familiarity with futures trading and price action concepts - Experience building trading automation systems for retail traders - Economic calendar API integration - Push notification and SMS integration (Firebase, Twilio, or equivalent) SECURITY & RELIABILITY: - Webhook authentication with secret token on all endpoints - Encrypted credential storage with no hardcoded API keys - VPS lockdown with SSH key only and firewall restricted to required IPs - Full audit logging with timestamps - Heartbeat monitoring during all sessions - Auto-shutdown logic when risk or malfunction thresholds are hit - Bot must be 100% deterministic and rules-based (no machine learning) DELIVERABLES: - Full source code (Pine Script, NinjaScript, middleware) - VPS deployed, configured, documented, and live - User guide for settings and session controls - Clean inline code documentation - Paper trading setup, monitoring, and results report - Go-live checklist - 30-day post-launch support SCREENING QUESTIONS (must answer all): 1. Have you built a webhook middleware server routing signals from TradingView to NinjaTrader 8? Describe the architecture. 2. Describe a NinjaScript project with fully automated execution - how did you handle order management, stop loss, and position tracking? 3. What is a Break of Structure in price action trading? How would you detect and code it in Pine Script? 4. Have you managed two independent trading accounts from a single middleware layer? How did you ensure no interference? 5. What is your approach to bot security for protecting webhook endpoints from unauthorized signals?
