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

Step 7: Iterate

If the user wants changes: 1. Pull fresh: `node scripts/pine_pull.js` (in case TV modified anything) 2. Edit locally 3. Push + compile 4. Screenshot to verify

IMPORTANT: Always compile after every change. Never claim "done" without a clean compile.
