ที่อัปเดต: Multi-Symbol Inside Bar Detector (4-Symbol Compression)
Multi-Symbol Inside Bar Detector (4-Symbol Compression)
Overview
Detects simultaneous inside bars across 4 symbols in real-time — a signal of market-wide compression that may precede directional moves. When all 4 symbols are "inside" (trading within the prior bar's range), the market is consolidating.
Monitor SPY, QQQ, DIA, IWM (or any 4 symbols you choose) on a single timeframe. No more chart hopping. Designed for Rob Smith's "The Strat" methodology and price action traders who trade compression setups.
🎯 Why This Matters
Inside bars indicate compression and consolidation.
When all 4 major ETFs simultaneously compress into inside bars:
Market is consolidating within a range
Volatility is contracting (not expanding)
A directional move may follow (direction unknown)
This is NOT a directional signal — it's a consolidation detector. You determine direction based on your analysis. This indicator identifies WHEN compression exists across multiple symbols.
✅ Key Features
✅ 4-Symbol Monitoring — Track 4 symbols simultaneously on one timeframe
✅ Visual Alerts — Bar coloring + optional "4-Inside" labels
✅ TradingView Alerts — Get notified when all 4 go inside simultaneously
✅ Live vs Confirmed Mode — Toggle between real-time (repaints) or bar-close confirmation (no repaint)
✅ Customizable — Any 4 symbols, any timeframe, custom colors
✅ Debug Table — See which symbols are inside (troubleshooting)
📊 How It Works
Inside Bar Definition (Rob Smith Standards)
An inside bar forms when:
High < Prior High AND
Low > Prior Low
Current bar trades entirely within prior bar's range.
Technical Implementation
pinescriptisInside(h, l, ph, pl) =>
na(h) or na(l) or na(ph) or na(pl) ? false : (h < ph and l > pl)
NA-safe: Handles missing data gracefully
Strict comparison: Uses < and > (not <= or >=)
Rob Smith compliant: Tick-perfect inside bar detection per Strat methodology
4-Symbol Requirement
Signal fires when ALL 4 symbols are inside bars simultaneously. If only 3 are inside → no signal. All 4 must compress together.
⚙️ Settings Guide
Symbols
Default: SPY, QQQ, DIA, IWM (broad market coverage)
Customize: Click to change to ANY 4 symbols
Popular Combinations:
Futures: ES, NQ, YM, RTY
Sectors: XLF, XLK, XLE, XLV
Mega Caps: AAPL, MSFT, GOOGL, AMZN
Timeframe
Default: 60 (1-hour bars)
What it does: Applies SAME timeframe to all 4 symbols
Examples: 5 (5min), 15 (15min), D (Daily)
Live Intrabar Mode
ON (default): Shows forming bars in real-time (repaints until close)
OFF: Waits for bar close (no repaint, confirmed only)
Use ON for: Live monitoring, intraday setups
Use OFF for: Alerts, backtesting, confirmed signals
Display Options
Show Labels: Toggle "4-Inside" labels on/off
Inside Bar Color: Default yellow (customize)
Show Debug Table: See per-symbol status (for troubleshooting)
🔔 Setting Up Alerts
Right-click chart → "Add Alert"
Condition: Select this indicator
Frequency: "Once Per Bar Close" (recommended for confirmed mode)
Alert fires when all 4 symbols go inside simultaneously (edge detection, not every bar)
💡 Example Trading Approaches
Note: These are educational examples, not trading advice. Past compression patterns do not guarantee future directional moves.
Approach 1: Higher TF Compression → Lower TF Trigger
1H chart: 4-symbol inside bar forms (compression)
15m chart: Monitor for directional break
Await confirmation with your analysis before entry
Approach 2: Daily Compression → Intraday Entries
Daily chart: All 4 compress (consolidation)
1H chart: Monitor for range expansion
Use your directional bias to determine position
Approach 3: Sector Analysis
Use sector ETFs (XLF, XLK, XLE, XLV)
When all 4 compress → observe which breaks first
Analyze sector strength/weakness patterns
🎯 Why 4 Symbols?
Market coverage: When SPY, QQQ, DIA, and IWM all compress together, it indicates broad market consolidation across multiple market-cap segments.
SPY: S&P 500 (large caps)
QQQ: Nasdaq 100 (tech)
DIA: Dow 30 (blue chips)
IWM: Russell 2000 (small caps)
Using 4 major indices helps filter noise from single-symbol compression.
⚡ Quick Start
Add indicator to chart

🔒 Technical Details
Code Quality
✅ PineScript v6 (latest)
✅ NA-safe logic (handles missing data)
✅ Rob Smith Strat standards (strict tick tolerance)
✅ No repainting (in confirmed mode)
✅ Efficient performance (max_bars_back=2)
✅ Open-source (educational transparency)
Repainting Behavior
Live Mode (ON): Repaints until bar closes (shows forming bars)

⚠️ Important Disclaimers
Not financial advice: This indicator is for educational purposes and market analysis
No performance guarantees: Past patterns do not predict future results
Directional bias required: Inside bars indicate consolidation, not direction
Risk management essential: Always use proper position sizing and stops
Test before trading: Backtest on historical data and paper trade first
💬 Final Thoughts
Compression often precedes expansion, but direction remains uncertain. When multiple major indices compress simultaneously, it indicates market-wide consolidation. This indicator helps identify those moments across 4 symbols — no more chart hopping, easier pattern recognition.
Use it as one component of your analysis, combine with your directional methodology, and always manage risk appropriately.
Happy trading! 📈

เอกสารเผยแพร่
Update: Added adjustable symbol threshold (k-of-4)New "Min symbols inside" setting lets you choose how many symbols must be inside bars to trigger (1-4). Previously required all 4. Set to 3 to catch setups where 3 symbols are compressing while one may have already broken out. Labels now show dynamic count (e.g. "3/4 Inside"). Default remains 4/4 for existing users — no changes to current behavior unless you adjust the setting.
เอกสารเผยแพร่
Show symbol names: Toggle between count display (3/4 Inside) or symbol names (SPY QQQ DIA Inside) showing which symbols are compressing.Live & confirmed labels: Live signals now show as outlined labels on the current bar. Confirmed signals lock in as solid labels on bar close.
Show only live signals: Toggle to hide all historical labels and only display compression happening right now.
Historical display control: Choose how many past setups to show — Last 3, 5, 10, 20, 50, 100, or Max 500.

Removed old "Live Intrabar" toggle in favor of the new live/confirmed label system.สคริปต์โอเพนซอร์ซ
