I have an arbitrage strategy sketched out in TradingView and now want it fully automated. The core logic has to be written in Pine Script, then connected to live order execution on Binance, Coinbase, and Kraken. Alongside the live deployment I also need: • A reliable back-testing module so I can replay the script on historical data directly inside TradingView and export key metrics. • Real-time execution that listens to WebSocket price feeds and pushes orders the instant a spread opens. • Embedded risk-management controls—position sizing, max daily loss, and exchange-specific rate-limit handling—hard-coded, not just comments. I am comfortable spinning up servers myself, so you can choose whatever bridge you like (Python + CCXT, Node, Go, etc.) as long as the code is clean, documented, and keeps latency low. Hand-over is complete when: 1. The Pine Script compiles without error and raises alerts exactly at my defined triggers. 2. The bridge script captures those alerts (or direct API calls) and posts test orders on all three exchanges in under a second. 3. Back-test results inside TradingView match the live fill logic in at least three replay sessions I will specify. 4. I receive concise setup instructions so I can redeploy or extend the bot on my own. If you have prior examples of multi-exchange Pine-based automation, that will speed things up. Looking forward to working together.
