Pine Script Mastery

What this skill does: Activates elite-level Pine Script capability.
Not just code generation — complete trading system architecture.
Strategy logic, indicator design, risk management, backtesting integrity,
publication-ready structure, and Pine Script v5/v6 mastery in one skill.

Reference Architecture

Standard task: Read language-mastery.md + relevant reference.
Full strategy build: Read all five files.

Execution Protocol

STEP 1 — Classify the Request

CODEBLOCK0

STEP 2 — Pre-Code Intelligence Gathering

Before writing a single line, extract:

CODEBLOCK1

If information is missing for a strategy build → ask before coding.
If request is clear → proceed immediately.

STEP 3 — Architecture Design (Strategy Builds)

Read references/strategy-design.md and design before coding:

CODEBLOCK2

STEP 4 — Write Production-Grade Code

Read references/language-mastery.md before writing.
Read references/quality-standards.md to apply all standards.

Every script must have:

CODEBLOCK3

Code structure order:

1. 1. Version declaration + header comment
2. INLINECODE9 or strategy() declaration with all parameters
3. Input groups (organized, labeled, with tooltips)
4. Core calculations
5. Signal logic
6. Risk management
7. Strategy entries/exits (if strategy)
8. Plots and visuals
9. Alerts
10. Dashboard table (if needed)

STEP 5 — Validate Before Delivering

Run this checklist on every output:

CODEBLOCK4

STEP 6 — Deliver With Context

Every code delivery includes:

1. What it does — plain English, 2-3 sentences

2. How to use it — specific settings, what to look for

3. Optimization hints — which inputs to tune first

4. Known limitations — honest about what it doesn't handle

5. Risk warning — always include for strategies:

⚠️ *Backtest results do not guarantee future performance.

Always validate on out-of-sample data and demo trade before going live.*

Strategy Design Principles

These apply to every strategy output regardless of complexity:

The Signal Quality Hierarchy

Tier 1 — Price action (most reliable, no lag)
Tier 2 — Volume confirmation (validates moves)
Tier 3 — Momentum oscillators (RSI, MACD — confirm, don't lead)
Tier 4 — Moving averages (trend context only — laggy for entry)

The Repainting Rule

• - request.security() without INLINECODE12
• Using high[0] or low[0] in real-time bar calculations
• INLINECODE15 / ta.pivotlow() — these inherently repaint

Always use barstate.isconfirmed for alert conditions.

The Overfitting Warning

Pine Script v6 Key Differences (vs v5)

Pine Script v6 was released December 2024. Future updates apply exclusively to v6.

Key changes from v5:
CODEBLOCK6

2025 updates: Scope limit removed (was 550, now unlimited). String length increased 10x to 40,960 characters. Pine Editor moved to side panel with word wrap support.

When to use v6: new scripts that need dynamic request.*() calls,
or when scope/string limits were previously a constraint.
When to stay on v5: maximum community compatibility needed.

Quick Reference — Most Used Patterns

Multi-Timeframe Analysis

ATR-Based Dynamic Levels

Strategy Entry with Risk Management

Dashboard Table

Confirmed Alerts (No Repainting)

alertcondition(long_signal and barstate.isconfirmed,
     title="Long Signal",
     message="{{ticker}} — Long signal on {{interval}}")

Teaching Mode

When the user asks to learn or understand something:

1. 1. Explain the concept — plain English first, no jargon
2. Show minimal example — smallest possible code that demonstrates it
3. Show real-world application — how it's actually used in a strategy
4. Common mistakes — what trips people up
5. Next step — what to learn after this

Never dump the full Pine Script manual. Teach the specific concept needed,
with just enough context to make it click.
