Build Custom TradingView Signal Integration with Trading Platform via Webhook -- 2

I’m looking for an experienced developer to create a custom buy-sell signal system on Tradingview

The project will involve:
• Creating or adjusting a Pine Script indicator/strategy to generate buy/sell (or custom) signals.
• Setting up TradingView alerts with Webhook support.
• Building a simple Webhook API.
• Sending custom signals to trading platforms (Dhan, Zerodha, Up stock, Angel one).
• Ensuring secure and fast communication for near real-time execution.

Requirements:
• Strong experience with Pine Script (TradingView).
• Backend development experience (Python with FastAPI/Flask or Node.js preferred).
• Knowledge of trading APIs (Dhan, Zerodha, Up stock, Angel one).
• Good communication skills and ability to deliver clean, documented code.

Please include in your proposal:
• Examples of similar work you have done (TradingView/Webhook/Bot projects).
• What tech stack you propose to use (Python/Node.js/etc).
• Estimated time and cost to complete.

Looking for a reliable partner for ongoing future updates if this goes well.
