How to vibe code custom trading indicators with the TradingView MCP + Claude Fable 5.


I'm not technical at all, and I was able to use the TradingView MCP to create wildly effective market indicators.
Every trader should set this up.
Nobody else on the timeline is talking about this. You'll want to save this one:
Set up requirements:
- Claude Code
- TradingView Desktop App
- Node.js v18+
Step 1. Install the TradingView MCP
Open Claude Code and run this prompt:
"Install the TradingView MCP server

Step 2. Describe your indicator in plain English to Fable (or Opus)
Create a new folder called "Vibe-Coding Indicators" and open it in Claude Code.
Then describe your strategy like you'd explain it to another trader.
Don't think about code - just think about conditions.
Use this structure:
"I'm building a trading indicator for TradingView in Pine Script V6. I want a buy signal that fires when [insert your conditions]."
(you can even have Fable research for you)
Step 3. Deploy to TradingView
Copy the Pine Script Claude generates.
Inside TradingView:
- Click "Indicators" in the top menu
- Go to "My Scripts" → New Script
- Paste the code starting on Line 1
- Click "Add To Chart"
Your indicator is now live.
Pro tips:
- Test on higher timeframes first (HTF signals are cleaner than LTF)
- Add alerts: "Set an alert anytime [x] happens."
- Backtest it: "Turn my indicator into a backtestable strategy."
- Debug with Opus + High Effort if you hit errors
Complete game changer.
