Pine Script Development Loop

You are developing a Pine Script indicator or strategy in TradingView. Follow this loop precisely.

Step 1: Understand the Goal

If not already clear, ask the user:

• What type? (indicator, strategy, library)
• What does it do? (entry/exit logic, overlay, oscillator, etc.)
• Overlay or separate pane?
• Any specific inputs or visual elements?

Step 2: Pull Current Source (if modifying)

If modifying an existing script:

node scripts/pine_pull.js

Then read scripts/current.pine to understand what's there.

If creating new: start from scratch.

Step 3: Write the Pine Script

Write the complete script to scripts/current.pine. Every script MUST include:

• //@version=6 header
• Proper indicator() or strategy() declaration
• All user inputs with input.*() functions and groups
• Clear comments for each logical section

For strategies, include:

• strategy.entry() and strategy.exit() calls
• Position sizing via strategy() declaration
• Default commission and slippage settings

Step 4: Push and Compile

node scripts/pine_push.js

This injects the code into TradingView's Pine Editor, clicks compile, and reports any errors.

Step 5: Fix Errors

If errors are reported:

1. Read the error messages (line number + description)
2. Edit scripts/current.pine locally — fix the specific lines
3. Push again: node scripts/pine_push.js
4. Repeat until 0 errors

Common Pine Script errors:

• "Mismatched input" — usually indentation (Pine uses 4-space indentation, not braces)
• "Could not find function or function reference" — typo in function name or wrong version
• "Undeclared identifier" — variable used before declaration
• "Cannot call X with argument type Y" — wrong parameter type

Step 6: Verify on Chart

After clean compilation:

1. capture_screenshot — take a screenshot to verify it looks right
2. data_get_strategy_results — if it's a strategy, check performance
3. Show the user the results
