Smart NR2-NR20 and Inside Bar (Zeiierman)█ Overview
Smart NR2–NR20 + Inside Bar (Zeiierman) is a compression + breakout scanner that searches for the tightest Narrow Range (NR) condition across NR2…NR20, plus optional Inside Bar detection. When a valid compression forms, it draws a box around the setup, projects the high/low levels forward, and triggers on the first breakout. Optional Trend Filter logic can restrict triggers to trend-aligned breakouts, and optional Exit markers can annotate TP / SL / Time exits after a trigger.
🔘 What It Detects
The Smart Narrow Range (NR2…NR20) script continuously checks NR lengths from 2 to 20 and selects the most extreme contraction (tightest relative range vs history) inside the current Look Back window, highlighting the strongest “compression” zones where expansion risk is building. Optionally, it can also treat an Inside Bar as a valid compression trigger.
█ How It Works
⚪ 1) Compression Scan (NR Ranking Engine)
For each bar, the script evaluates NR2…NR20:
It calculates the N-bar range (highest high − lowest low).
It compares that range to prior N-bar ranges over Look Back.
It ranks candidates by “tightness” and keeps the strongest one.
Key effect:
Higher Look Back = fewer but higher-quality compressions
Lower Look Back = more frequent compressions
⚪ 2) Adaptive Look Back (Static or ADX-Adaptive)
Look Back can be:
Static: fixed comparison window
ADX Adaptive: Look Back dynamically shifts between LB Min and LB Max depending on trend strength
Conceptually:
Higher ADX (strong trend) — shorter Look Back (more responsive)
Lower ADX (chop/range) — longer Look Back (more selective)
█ How to Use
⚪ Bullish Setup
Wait for a tight range to form
Enter on a breakout above the range high
Stop below the opposite side of the range
Target a multiple of the range size or trail with momentum
Optional: wait for a small breakout retest before entering
⚪ Bearish Setup
Wait for a tight range to form
Enter on breakout below the range low
Stop above the opposite side of the range
Target a multiple of the range size or trail with weakness
Optional: enter on breakdown retest
█ Settings
Enable Inside Bar — toggles Inside Bar detection.
Look Back (compare window) — history window used to judge contraction quality.
Enable Trend Filter — gates long/short triggers relative to Trend MA.
Show Trend MA — plots the Trend MA on chart.
Trend MA Mode — Static or NR-Adaptive (length follows Look Back × multiplier).
MA Type — EMA or RMA smoothing for the Trend MA.
NR — MA Multiplier — scales adaptive MA length from Look Back.
Static MA Length — used when Trend MA Mode is Static.
Look Back Mode — Static or ADX Adaptive.
ADX Length / ADX Low / ADX High — controls adaptive response to trend strength.
LB Min / LB Max — bounds for adaptive Look Back range.

NR4 & NR7 with Breakouts [LuxAlgo]NR4 & NR7 with Breakouts is a simple indicator that utilizes the NR4 and NR7 candle patterns to display candle ranges and signals from range breakouts.
🔶 USAGE
The Narrow Range Patterns are candle formations determined by the last candle having a narrower (high-low) range than the previous number. This indicator showcases the 2 most recognized Narrow Range Patterns, which are the 4 and 7 bar variants (NR4 and NR7).
These patterns, introduced by Toby Crabel, are thought to provide insight for potential market breakouts by identifying periods of low volatility indicated by a candle with a small range. This is due to the idea that markets often move from periods of low volatility (contraction) to high volatility (expansion), and the NR4 and NR7 patterns help spot these transitions.
By utilizing these patterns, traders are better able to anticipate and respond to market shifts for better decision-making and risk management.
NOTE: These patterns have traditionally been studied on the Daily Timeframe Chart. This indicator allows the user to select a timeframe to generate these patterns from. It is suggested to be mindful of this when considering these patterns.
In this indicator, on the bar after the pattern is detected, the Narrow Range Bar will be highlighted with a zone, and lines displaying the range will extend from it. These ranges are helpful for providing levels to set limit orders and for managing risk.
Users are able to adjust which pattern they want visualized on their chart, please note;
All NR7s are NR4s but not all NR4s are NR7s.
Because of this, you will notice that when selecting "NR4" to display, the colors will change, but the detected ranges will not change.
🔹 Signals
When a Narrow Range Bar is detected, the script will wait for the price to close outside of the Range, then a signal will fire indicating the direction of exit. The signals are produced from the last NR4 or NR7 and will have the potential to fire from that range until a new NR4 or NR7 is detected.
After a signal fires, the logic goes into a "reset" period where it will wait for the price to reach the Range Mean before firing another signal.
These signals can be anticipated by considering the underlying logic and watching price approach the range extremities, and can be improved by utilizing other market information for confluence.
🔶 SETTINGS
Timeframe: Choose which timeframe to identify the NR4 and NR7 Pattern on. This must be Higher than the chart timeframe.
Pattern Type: Choose which (or all) patterns to display.

Compression Patterns (w/ Trend + Proximity Filter)🧠 Description:
This indicator identifies high-probability price compression patterns within trending environments — a setup prized by experienced swing and day traders alike. It combines the classic NR4, NR7, 2-Bar NR, 3-Bar NR, and Inside Day formations with a powerful trend filter and proximity logic to deliver clear, focused signals.
🔍 What's Inside:
▪️ Compression Patterns
The core of this tool lies in the logic of price compression. These patterns signal the market taking a breath — volatility contracts, volume dries up, and price coils like a spring.
When this happens in the right context, the next move is often explosive.
NR4 / NR7: Narrowest range in 4 or 7 bars — excellent for spotting the quiet before the storm.
2-Bar NR / 3-Bar NR: These identify the tightest consecutive 2 or 3-day ranges over the past 20 days — contextually rare and powerful.
Inside Day: A simple but highly effective consolidation pattern, especially when it clusters around key moving averages.
▪️ Trend Filter (EMA Stack)
You could say this is where most indicators fall apart — no context.
This one doesn’t make that mistake.
Signals only fire when the 10 EMA > 20 EMA > 50 EMA, and price is above the 20 EMA. That’s a strong, established uptrend — the only environment where breakouts are statistically favourable.
Why?
Because trend following works.
It may not give you fixed daily returns, but it’s the only strategy with theoretically infinite profit potential. You risk little, trade less, and position yourself for rare but massive moves. That’s the edge.
▪️ Proximity Filter (1 ATR to EMA)
We’ve added another layer of discipline. Signals only fire when price is:
Within 1 ATR of the 10 EMA (if price is above it), or
Within 1 ATR of the 20 EMA (if price is below the 10 EMA)
This ensures you’re not chasing. You’re waiting for tight, controlled pullbacks into dynamic support — exactly where institutions add size, not exit.
⚙️ Fully Customisable:
Toggle visibility of each pattern
Custom colours and transparency for label & background
Adjustable ATR length and multiplier
Change label text if needed (useful for translations or tweaks)
🎯 Ideal Use Case:
Swing trading off the daily chart
Day trading with VWAP/MACD filters (in alternate versions)
Supplementing price action strategies
🔚 Final Word:
This isn’t an “everything scanner.”
It’s a discerning sniper scope for traders who wait patiently for clean trends, tight consolidations, and perfect proximity — then strike.

Simple RangeThe daily price range is a good proxy to judge an instrument’s volatility. I have combined multiple concepts in this indicator to display information regarding the daily price range & its volatility.
A trading period's range is simply the difference between its high and the low. This script shows the daily high-to-low range of the price as a column chart. It has 3 main components:
1. Narrow-range days (NR7) & Wide-range Days (WR20) - as plot columns
Original concept from Thomas Bulkowski
Modified from "NR4 & NR7 Indicator" script by theapextrader7
Modified from "WR - BC Identifier" script by wrpteam2020
Narrow range days mark price contractions that often precede price expansions. This script uses NR7 (narrow range 7) as a narrow-range day. This value can be changed by the user if, instead of an NR7, he or she wishes to use NR4 or NR21, or any other interval of his or her choice. NR7 is an indecisive trading day in which the range is narrower than any of the previous six days (a total of 7 days). This is a popular concept given by Thomas Bulkowski. A breakout is said to occur when price closes above the top or below the bottom of the NR7. Upside breakout of an NR 7 candle with high volumes indicates bullishness.
Similarly, highs & lows of wide-range bars (on big volumes) are also significant reference levels for price. Wide-range candle are identified by size of the body candle (open - close). The script compares the size of previous 20 candles to identify WR20 candles. This value can also be changed by the user.
The script shows NR7 & WR20 as orange & blue bars, respectively.
The user can also turn on the option to identify a big high-to-low range candle greater than a pre-defined threshold (default is 5%). These show up as green or red bars.
2. TTM Squeeze - as background
Original concept from John Carter's book "Mastering the Trade"
Based on "Squeeze Momentum Indicator" script by LazyBear
John Carter’s TTM Squeeze indicator looks at the relationship between Bollinger Bands and Keltner's Channels to help identify period of volatility contractions. Bollinger Bands being completely enclosed within the Keltner Channels is indicative of a very low volatility. This is a state of volatility contraction known as squeeze. Using different ATR lengths (1.0, 1.5 and 2.0) for Keltner Channels, we can differentiate between levels of squeeze (High, Mid & Low compression, respectively). Greater the compression, higher the potential for explosive moves.
In the script, the High, Mid & Low compression squeezes are depicted via the background color being red, orange, or yellow, respectively.
3. Average Daily Range - as table
Original idea by alpine_trader
Modified from "ADR% - Average Daily Range % by MikeC" script by TheScrutiniser
Average Day Range (ADR) tells how much the price moves between the high and low on a given day. This is the day Range, which is then averaged to create ADR. The script uses an average of the last 20 days to calculate the ADR. Unlike ATR (Average True Range), this excludes Gaps.
The script displays the ADR as a % value in a table.
If you want to find stocks that move a lot on an average on most days, then look for stocks that have ADR% of 5% or more.
If you prefer lower volatility stocks, focus on stocks with lower ADR% values, such as 2% or less.
How it comes together
For a bullish "momentum burst", or a velocity trade:
Select stocks with Average Day Range % (ADR) greater than 5
Identify significant reference price levels via highs & lows of WR20 bars (on big volumes)
Wait for a decent mid-to-high compression squeeze
Look for clusters of NR7 candles in the consolidation
Any breakout from this consolidation should be accompanied by more than average (preferably pocket pivot) volumes

NR7 Indicator Based on Thomas Bulkowski's TheoriesThis NR7 indicator was built on the concept by Thomas Bulkowski and his ThePatternSite. NR7 is based on high to low price range (true range) that is the smallest of the prior 6 days (7 days total), when one NR7 shows, it means that today's candle body (low to high) is the narrowest of the past 7 days. Then if the current close is higher than the NR7's high, we call it a bullish breakout; and if the current close is lower than the NR7's low, we call it a bearish breakout. Regardless the direction, once the current close price goes above or below the high or low of the NR7 candle, we call it a "breakout" in this strategy. Bulkowski suggested on his website that only gave 7 calendar days (NOT trading days) for the symbol to breakout after NR7 occurs, and if the underlying asset does not breakout within 7 calendar days after one NR7 occurs, we would abandon this NR7 signal and start recounting again.
Since most securities/indexes do not trade on the weekends and have no data available, I switched 7 calendar days breakout limit to 5 trading days breakout limit, which will work on most assets. However, if you are trading cryptocurrencies or forex which have data on the weekends, feel free to add 2 more days to finish the NR7 count, all you have to do is to add "Buy6", "Buy7", "Sell6" and "Sell7" under line 11 and line 17, then add the senarioes under those "if" statements.
Every "NR7" will show up on the chart with a cross symbol and text next to it, then green arrowups show bullish signals and red arrowdowns show bearish signals. Bulkowski also added a "CPI" index on his NR7 strategy, this indicator does not include that "CPI equation" for simplicity purposes and other time frame tradings other than just weekly signals.
