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
