OPEN-SOURCE SCRIPT
27.05.2026
***
Before presenting this project, I would like to express my sincere gratitude to all the developers, traders, coders, researchers, and members of the TradingView community whose ideas, indicators, concepts, and open-source contributions helped inspire this work.
Modern technical analysis is built upon decades of shared knowledge.
Every moving average, volatility model, market structure concept, liquidity theory, trend engine, and smart-money framework exists because countless traders decided to share their discoveries with others.
This indicator is not the product of a single isolated idea.
It is the result of studying, combining, refining, and evolving many approaches developed by talented authors across the trading community.
Special appreciation goes to the creators and researchers behind:
* Supertrend algorithms
* ATR-based volatility systems
* Supply & Demand methodologies
* Fair Value Gap concepts
* Smart Money Concepts (SMC)
* Volume analytics
* Multi-timeframe trend models
* Session-based trading frameworks
* Institutional liquidity mapping techniques
Open-source collaboration is one of the greatest strengths of the TradingView ecosystem.
The willingness of traders to publish ideas, share code, test concepts, and improve each other’s work continues to push technical analysis forward.
This project was created with respect for that spirit of collaboration.
Thank you to everyone whose work, directly or indirectly, contributed to the development of this indicator.

# 3ST NR — Advanced Non-Repainting Market Structure & Trend Engine
The **3ST NR** indicator is a complete institutional-style trading framework built around a triple Supertrend architecture, market condition analysis, ranked supply & demand zones, liquidity imbalance detection, multi-timeframe EMA mapping, and session-aware filtering.
Designed for traders who want more than simple buy/sell signals, this system transforms raw price action into a fully contextual trading environment.
---
## Core Concept
At the heart of the indicator are **three independent Supertrend engines** with different ATR sensitivities:
* Fast Supertrend → short-term momentum
* Mid Supertrend → directional confirmation
* Slow Supertrend → macro trend structure
A bullish state appears when the fast and mid Supertrends align upward.
A bearish state appears when both align downward.
Unlike many retail indicators, the script uses:
* confirmed candles only
* `barstate.isconfirmed`
* no future-looking calculations
* non-repainting logic
This creates stable and reliable market structure signals.
---
# Market Intelligence Engine
The script does not blindly trade every signal.
Instead, it evaluates the quality of the environment using a dynamic market engine:
## Trend Detection
Trend strength is calculated using:
* ATR volatility
* distance from EMA 21
* normalized momentum
The market is automatically classified into:
* **TREND**
* **MIX**
* **CHOP**
This allows traders to avoid low-quality ranging conditions.
---
# Volume Classification Engine
Volume is analyzed relative to a 20-period moving average.
The system categorizes activity into:
* LOW
* NORMAL
* HIGH
* SPIKE
This creates optional institutional participation filters, helping traders focus only on moments where real liquidity enters the market.
---
# Smart Session Engine
The indicator is fully session-aware.
It recognizes:
* New York Session
* London Session
* Asia Session
* US Pre-Market
Optional filters allow trading only during the highest-liquidity market windows.
This is especially powerful for:
* index futures
* NASDAQ
* forex
* scalping environments
---
# Multi-Layer EMA Structure
The script overlays multiple EMA systems simultaneously:
## Intraday EMAs
* EMA 9
* EMA 20
* EMA 62
* EMA 200
## Higher Timeframe Daily EMAs
* Daily EMA 3
* Daily EMA 9
* Daily EMA 20
* Daily EMA 50
* Daily EMA 100
* Daily EMA 200
This creates a complete multi-timeframe trend map directly on lower timeframes.
The higher timeframe EMAs act as:
* institutional support/resistance
* trend magnets
* reversal zones
* momentum confirmation layers
---
# Dynamic Daily Levels
The indicator automatically plots:
* Daily Open
* High of Day (HOD)
* Low of Day (LOD)
These levels dynamically update throughout the session and extend across the chart.
They serve as:
* liquidity references
* intraday breakout zones
* mean reversion levels
* trend continuation triggers
---
# Ranked Supply & Demand System
One of the most advanced parts of the script is the adaptive supply & demand engine.
The indicator:
* detects swing pivots
* builds dynamic zones
* ranks them using a proprietary scoring system
* continuously updates strength based on:
* mitigation
* volume
* trend alignment
* touch count
* age
* volatility
Zones are automatically classified as:
* strong support
* weak support
* strong resistance
* weak resistance
* mitigated zones
* broken zones
Each zone includes:
* visual strength bars
* bullish/bearish dominance percentages
* mitigation tracking
* automatic cleanup logic
The system behaves similarly to institutional order-flow mapping.
---
# Fair Value Gap Detection (FVG)
The script also detects non-repainting Fair Value Gaps.
Bullish and bearish imbalances are automatically drawn when inefficient price delivery occurs between candles.
These zones help traders identify:
* liquidity voids
* inefficiencies
* continuation structures
* smart-money displacement
---
# Intelligent Dashboard
A built-in real-time dashboard displays:
* current market condition
* volume state
* active session
* trend strength
* bullish/bearish status
This creates a compact decision-making center directly on the chart.
---
# Non-Repainting Philosophy
The entire system is designed around signal stability.
Key anti-repaint mechanisms include:
* confirmed candle validation
* no future bar references
* `lookahead_off`
* closed-bar signal confirmation
* structural pivot validation
This makes the indicator suitable for:
* live trading
* alerts
* automation
* strategy development
* discretionary execution
---
# Best Use Cases
The indicator performs exceptionally well in:
* NASDAQ scalping
* index futures
* forex intraday trading
* momentum trading
* session breakout strategies
* smart money concepts
* trend continuation systems
Especially effective on:
* 1-minute
* 3-minute
* 5-minute
* 15-minute charts
---
# Key Features Summary

# Final Philosophy
3ST NR is not just another indicator.
It is a complete market structure framework combining:
* trend analysis
