Multiple Smoothed Moving Averages

Multiple Smoothed Moving Averages (SMMAs)
This indicator displays up to 5 Smoothed Moving Averages (SMMAs) on your chart, providing a comprehensive view of multiple trend timeframes simultaneously.

WHAT IS A SMOOTHED MOVING AVERAGE?
═══════════════════════════════════════
The Smoothed Moving Average (SMMA), also known as the Running Moving Average (RMA), is a type of moving average that provides more smoothing than a Simple Moving Average (SMA).
Unlike SMA which gives equal weight to all values in the period, SMMA uses a recursive formula that gives more weight to previous SMMA values, resulting in:
- Smoother price action with less noise
- Slower response to recent price changes
- Better identification of longer-term trends
- Reduced false signals in choppy markets
CALCULATION METHOD:
- First value: Simple Moving Average of the initial period
- Subsequent values: (Previous SMMA × (Length - 1) + Current Price) / Length
This recursive nature makes SMMA particularly effective for identifying sustained trends while filtering out short-term volatility.

FEATURES
═══════════════════════════════════════
✓ 5 Independent SMMAs: Each with its own configurable period length
✓ Individual Toggles: Show/hide each SMMA independently
✓ Distinct Colors: Easy visual identification of each moving average
✓ Customizable Lengths: Adjust each period to match your trading strategy
✓ Shared Source: All SMMAs calculate from the same price source (default: close)
✓ Overlay Display: Plots directly on the price chart
═══════════════════════════════════════
DEFAULT SETTINGS
═══════════════════════════════════════
- SMMA 1: 30 periods (Blue)
- SMMA 2: 50 periods (Orange)
- SMMA 3: 100 periods (Green)
- SMMA 4: 200 periods (Purple)
- SMMA 5: 300 periods (Red)
All SMMAs are enabled by default.
═══════════════════════════════════════
HOW TO USE
═══════════════════════════════════════
TREND IDENTIFICATION:
- Price above all SMMAs = Strong uptrend
- Price below all SMMAs = Strong downtrend
- Price between SMMAs = Transitional phase or consolidation
SUPPORT & RESISTANCE:
- SMMAs often act as dynamic support in uptrends
- SMMAs often act as dynamic resistance in downtrends
- Longer-period SMMAs (200, 300) provide stronger S/R levels
CROSSOVER SIGNALS:
- Faster SMMA crossing above slower SMMA = Bullish signal
- Faster SMMA crossing below slower SMMA = Bearish signal
MULTIPLE TIMEFRAME ANALYSIS:
- Short-term trends: 30, 50 periods
- Medium-term trends: 100 periods
- Long-term trends: 200, 300 periods
═══════════════════════════════════════
CUSTOMIZATION
═══════════════════════════════════════
INPUTS TAB:
- Adjust each SMMA length to suit your trading timeframe
- Toggle individual SMMAs on/off using checkboxes
- Change the source (close, open, high, low, hl2, hlc3, ohlc4)
STYLE TAB:
- Modify line colors for each SMMA
- Adjust line thickness and style
- Change transparency levels
═══════════════════════════════════════
NOTES
═══════════════════════════════════════
- This indicator uses the mathematically correct SMMA calculation with the recursive formula
- All calculations are performed on every bar to ensure data consistency
- SMMAs respond more slowly than EMAs but faster than WMAs to price changes
- Best used in combination with other technical analysis tools
- Use on any timeframe
═══════════════════════════════════════
Perfect for traders who want a clear, multi-timeframe view of market trends using the smooth, reliable SMMA calculation method.
