SIL Momentum & Participation Engine
The **SIL Momentum & Participation Engine** is an oscillator designed to answer three questions:
1. Is there directional force?
2. Is volume participating in the move?
3. Is the price movement efficient?
It does not generate entries, BUY/SELL signals, stop-losses, or targets.
### MOM — Momentum
The thick main line combines three speeds of the Elder Force Index:
- Fast EFI reacts quickly.
- Medium EFI stabilizes the reading.
- Slow EFI measures persistent force.
Interpretation:
- Above the neutral zone: bullish force.
- Below the neutral zone: bearish force.
- Inside the neutral zone: insufficient or undefined force.
- Rising: positive acceleration.
- Falling: negative acceleration.
Its color also reflects movement efficiency:
- Bright green/red: efficient directional movement.
- Faded green/red: direction exists, but efficiency is weak.
- Grey: neutral momentum.
### PART — Participation
The thinner line is derived from a transformed Accumulation/Distribution calculation.
It indicates whether volume participation supports the movement:
- Positive: bullish participation.
- Negative: bearish participation.
- Near zero: weak or balanced participation.
With confirmation coloring enabled:
- Cyan: participation confirms bullish momentum.
- Orange: participation confirms bearish momentum.
- Grey: Momentum and Participation disagree or are in transition.
### M-AVG — Momentum Average
The thin white line is a short moving average of Momentum.
It does not determine direction. It helps reveal acceleration and deceleration:
- MOM moving away from M-AVG: force is accelerating.
- MOM approaching M-AVG: force is weakening.
- MOM crossing M-AVG: relative velocity has changed, not necessarily the trend.
### KER — Efficiency
The Kaufman Efficiency Ratio measures how directly price is moving.
- High KER: clean and efficient movement.
- Medium KER: usable movement with some noise.
- Low KER: substantial internal movement with little net progress.
KER does not define direction. By default, it changes the color or transparency of the MOM line. Its separate diagnostic line is optional.
### `+σ` and `−σ` Bands
These are statistical bands calculated around Momentum:
- MOM inside the bands: normal recent behavior.
- MOM approaching a band: relatively strong momentum.
- MOM crossing a band: unusual expansion.
- Narrow bands: compression.
- Wide bands: increased momentum variability.
Crossing a band is not automatically a reversal signal. It may indicate strong continuation.
### Energy Field
The green or red shaded area between Momentum and its statistical average represents directional acceleration:
- Stronger shading: Momentum is gaining energy.
- Fading shading: Momentum is decelerating.
- Green: bullish energy.
- Red: bearish energy.
## Typical readings
**Healthy bullish continuation**
```text
MOM positive and rising
PART positive
High KER
Green energy increasing
```
**Healthy bearish continuation**
```text
MOM negative and falling
PART negative
High KER
Red energy increasing
```
**Movement without participation**
```text
MOM directional
PART neutral or opposite
```
Price is moving, but volume participation does not confirm it.
**Loss of force**
```text
MOM remains directional
MOM approaches M-AVG
Energy fades
KER begins to decline
```
The movement continues, but it is becoming less efficient.
**Choppy conditions**
```text
MOM repeatedly crosses zero
PART changes direction frequently
Low KER
Weak energy
```
The central idea is:
> `MOM` shows force, `PART` shows whether volume participates, and `KER` shows whether the movement is efficient.
It is a context and confirmation tool, not an entry system.
