Ninja Indicator by Simhadri

# Ninja Indicator by Simhadri (NISS) - Description

## Overview
The Ninja Indicator System by Simhadri (NISS) is a sophisticated momentum oscillator designed to identify trend changes and generate trading signals. This indicator combines multiple exponential moving averages (EMAs) to create a smooth, responsive oscillator that helps traders identify bullish and bearish market conditions.

## Key Features

### Dual Mode Operation
- **Ninja Mode**: Uses 6 fast EMAs (3, 5, 8, 10, 12, 15 periods) and 6 slow EMAs (30, 35, 40, 45, 50, 60 periods)
- **Super Ninja Mode**: Enhanced version with 11 fast EMAs (3-23 periods) and 16 slow EMAs (25-70 periods) for increased sensitivity

### Core Components
1. **NISS Fast Line**: Average of multiple short-term EMAs representing recent price action
2. **NISS Slow Line**: Average of multiple long-term EMAs representing the underlying trend
3. **NISS Oscillator**: Percentage difference between fast and slow lines, smoothed for clarity
4. **Signal Line**: EMA of the raw oscillator for generating crossover signals

### Visual Elements
- **Oscillator Line**: Changes color based on position relative to signal line (Blue above, Fuchsia below)
- **Signal Line**: White line for crossover reference
- **Neutral Zone**: Highlighted area between +0.20 and -0.20 levels
- **Reference Lines**: Horizontal lines at +0.20 and -0.20 for overbought/oversold conditions

## Input Parameters

### Timeframe Settings
- **Alternate Anchor TimeFrame**: Allows calculation on different timeframes (0-1440 minutes)
- **Source**: Price data source (default: close price)

### Calculation Settings
- **NISS Type**: Choose between "Ninja" or "SuperNinja" calculation methods
- **Oscillator Smoothing**: Smoothing length for the oscillator (1 = no smoothing)
- **Signal Length**: Period for the signal line EMA (default: 24)

### Display Options
- **Show Bullish/Bearish Zones**: Toggle for visual zone highlighting

## Trading Signals

### Primary Signals
- **Bullish Signal**: When NISS Oscillator crosses above the Signal Line
- **Bearish Signal**: When NISS Oscillator crosses below the Signal Line

### Signal Interpretation
- **Above Zero**: Generally bullish momentum
- **Below Zero**: Generally bearish momentum
- **Above +0.20**: Potential overbought conditions
- **Below -0.20**: Potential oversold conditions

## Alert System
The indicator includes built-in alert conditions for:
- Bullish crossover signals
- Bearish crossunder signals

## Usage Recommendations

### Best Practices
1. Use in conjunction with other technical analysis tools
2. Consider the overall trend direction
3. Watch for divergences between price and oscillator
4. Pay attention to signals near the neutral zone boundaries

### Timeframe Considerations
- Works on all timeframes
- Anchor timeframe feature allows multi-timeframe analysis
- Higher timeframes may provide more reliable signals

## Technical Notes
- Built on Pine Script v6
- Displays as a separate indicator panel (overlay = false)
