Strong Holders Momentum

This indicator is called "Strong Holders Momentum" (SH Momentum) and is a modified oscillator that analyzes the difference between two moving averages (fast and slow) across different timeframes. Its primary purpose is to identify trend strength and direction, as well as potential reversal points.

This indicator detects early momentum shifts in assets approaching key reversal zones by tracking:
- Convergence of the smoothed moving average (SMMA)
- Trend confirmation across multiple timeframes
- Visual assessment of momentum intensity

### Key Features:
1. Dual Smoothed Moving Averages (SMMA)
- Uses two modified moving averages (SMMA — Smoothed Moving Average) with different periods:
- `fast_length` (default: 4) — fast MA.
- `slow_length` (default: 12) — slow MA.
- The difference between them (`ma_diff = fast_ma - slow_ma`) generates the primary signal.

2. Higher Timeframe Analysis
- The indicator automatically calculates the moving average difference (`ma_diff`) on a higher timeframe (`res_multi` times larger than the current one) to determine the global trend.
- Example: If the current timeframe is 1H and `res_multi = 3`, the higher timeframe will be 3H.

3. Visualization:
- Histogram (bars) — displays the current `ma_diff` value. Color depends on the direction and position relative to zero.
- Lines — duplicates the histogram as a line.
- Background — shaded red/green based on the higher timeframe trend direction.

4. Color Scheme:
- Above zero and rising: Light green (`#81C784`).
- Below zero and rising: Deep green (`#26A69A`).
- Above zero and falling: Bright red (`#EF5350`).
- Below zero and falling: Light pink (`#FFCDD2`).

Signal Interpretation:
- Green bars: Increasing bullish momentum.
- Red bars: Growing bearish pressure.
- Background color: Trend bias on the higher timeframe (red = bearish, green = bullish).

### Logic:
- A rising `ma_diff` indicates strengthening momentum.
- Zero-line crossovers may signal a trend reversal.
- Divergence between current and higher timeframes (e.g., uptrend on lower TF vs. downtrend on higher TF) can warn of trend weakness.

### Applications:
- Trend strategies: Buy when the histogram rises above zero; sell when it falls below.
- Trend filter: Alignment of directions across timeframes strengthens signals.
- Divergences: Discrepancies between price and indicator may hint at reversals.

This indicator combines features of MACD (MA difference) and Momentum.
