IRONROD TRIGGER SYSTEM [NPR21]
DESCRIPTION
IronRod Trigger System is a momentum oscillator based on the Stochastic Momentum Index (SMI) that identifies trend changes, momentum shifts, and range-bound "chop" zones. Features color-changing SMI lines, histogram columns showing momentum strength, and a visual chop zone that highlights when to trade versus when to stay on the sidelines.
The system combines momentum direction (green/red lines), momentum strength (histogram columns), and market context (chop zone cloud) into one clean visual package. The dynamic zero line changes color to signal trade conditions (cyan) versus hold conditions (orange).
What Makes It Unique:
Dual color-changing lines (SMI and AvgSMI) show momentum direction
Histogram columns display momentum strength
Chop zone cloud identifies low-momentum periods
Dynamic zero line (cyan = trade, orange = hold)
Three-color histogram (green = strong up, red = strong down, gray = weak)
Adjustable chop zone threshold
How to Use
THE DISPLAY
Lines:
Green = bullish momentum (rising)
Red = bearish momentum (falling)
Gray = neutral/sideways
Histogram Columns:
Green = strong bullish momentum
Red = strong bearish momentum
Gray = weak/choppy momentum
Zero Line:
Cyan (blue) = trade zone - momentum is directional
Orange = chop zone - momentum is weak, avoid trading
Chop Zone Cloud:
Gray shaded area = range where momentum is indecisive (±30 default)
TRADING STRATEGIES
1. Chop Zone Trading
Trade: Only when SMI is outside gray cloud AND zero line is cyan
Avoid: When SMI is inside cloud OR zero line is orange
Long: Green line appears above chop zone
Short: Red line appears below chop zone
This is the key feature - dramatically reduces whipsaws
2. Zero Line Crosses
Buy: SMI crosses above zero with cyan zero line
Sell: SMI crosses below zero with cyan zero line
Strongest signals when AvgSMI follows SMI across zero
Ignore crosses when zero line is orange (choppy)
3. Histogram Strength
Strong trend: Multiple consecutive green/red columns
Momentum building: Columns getting taller
Momentum fading: Columns turning gray = exit warning
Reversal signal: Gray columns after strong trend
4. Divergence Trading
Bearish divergence: Price higher high, SMI lower high → take red line signal
Bullish divergence: Price lower low, SMI higher low → take green line signal
Most powerful outside chop zone
ENTRIES & EXITS
Entries:
SMI line turns green outside chop zone (long)
SMI line turns red outside chop zone (short)
SMI crosses zero with cyan zero line
Exits:
SMI line changes color
SMI enters chop zone (orange zero line)
Histogram turns gray
Stops:
Below recent swing low (longs)
Above recent swing high (shorts)
ADJUSTING SETTINGS
Chop Zone (±) (default: 30):
Lower (15-25) = More trades, more whipsaws
Higher (35-50) = Fewer trades, higher quality
Adjust based on instrument volatility
Percent K Length (default: 5):
Lower (3-4) = More sensitive, faster signals - good for scalping
Higher (7-10) = Less sensitive, smoother - good for swing trading
Percent D Length (default: 4): Controls smoothing
SMI Bar Buffer (default: 4): Histogram color sensitivity
TIMEFRAME GUIDE
Scalping (1-5m): K=3, watch histogram color flips
Day trading (15-60m): Default settings, focus on zero crosses outside chop
Swing trading (4H-Daily): K=7-10, trade only strong trends outside chop
Key Settings
Percent K Length (default: 5): Lookback period - controls sensitivity
Percent D Length (default: 4): Smoothing period
Chop Zone (±) (default: 30): Range-bound zone threshold
SMI Bar Buffer (default: 4): Histogram color change sensitivity
Histogram Width (default: 1): Column thickness
Key Features
✅ Dual color-changing momentum lines
✅ Histogram columns show strength
✅ Chop zone cloud filters bad trades
✅ Dynamic zero line color
✅ Three-color histogram
✅ Adjustable chop threshold
✅ All timeframes
✅ Reduces whipsaws

Notas de prensa
Update Notes for Version 2.5 (January 09, 2025):- Added momentum-based triangle arrow signals that trigger on genuine SMI momentum shifts. Buy arrows (green triangles) appear when SMI momentum changes from falling to rising, while sell arrows (red triangles) appear when momentum shifts from rising to falling. These signals are independent of AvgSMI crossovers and based purely on the IronRod's internal momentum logic.
New features include separate offset controls for buy and sell arrows, allowing traders to position arrows optimally for visual clarity and prevent them from overlapping with the SMI lines. Default offset increased to 25 for improved visibility. ~ NPR21
Notas de prensa
Update Notes for Version 5.0 (January 09, 2025):- Major enhancement combining the power of SMI oscillator analysis with AGAIG fractal pivot detection. This version integrates the complete "As Good As It Gets" (AGAIG) price-action arrow system directly into the IronRod oscillator pane, providing traders with both longer-term trend confirmation from the SMI and immediate early-entry signals from AGAIG's fractal turn detection.
New Features:
- Complete AGAIG pivot detection system integrated into oscillator pane
Triangle arrows based on fractal price turns (independent of SMI crossovers)
Optional Buy/Sell text labels with full customization
Optional pivot dots showing high/low pivot points
Adjustable arrow offsets for optimal visual placement
"Ignore Last Bar" option for confirmed signals only
All AGAIG settings grouped for easy configuration
Enhanced color customization for all visual elements
How It Works:
- The IronRod system now displays AGAIG arrows based on price fractals (not SMI values), giving you early warning of potential turns while the SMI oscillator provides trend context and momentum confirmation. This dual-system approach allows scalpers to catch early entries with AGAIG signals while using SMI for trend filtering and position management.
Use Cases:
- Scalping: Use AGAIG arrows for entry timing, SMI for trend filter
- Day Trading: Combine both systems for high-probability setups
- Swing Trading: AGAIG for entries, SMI chop zone for avoiding ranges
