3-SMA/EMA Ribbon

### 3-MA Ribbon (EMA / SMA Switchable)

**What it is**
The 3-MA Ribbon overlays three configurable moving averages (Fast, Mid, Slow) and colours the space between them to show both *trend strength* and *trend clarity* at a glance. A single dropdown lets you choose whether those MAs are **EMAs** (react faster) or **SMAs** (smoother).

#### How the colour logic works

| MA order (Fast > Mid > Slow) | Ribbon | Meaning |
| ---------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------- |
| **Fast > Mid > Slow** | **Vivid Green** | Strong bullish stack |
| **Fast < Mid < Slow** | **Vivid Red** | Strong bearish stack |
| Any other order | Upper gap is soft green/red if the *upper* MA is above/below the *lower* one; lower gap is evaluated separately. Mixed colours = indecision / transition phase. | |

Opacity is lower (more solid) when the stack is perfect, higher (more transparent) when it’s mixed, so you instantly see how clean the trend structure is.

#### Visual cues

* **Fast MA** – dotted line (circles)
* **Mid MA** – dashed-look (crosses)
* **Slow MA** – solid line
All three line colours are separately customisable and are chosen to stay readable over both red and green fills.

Tiny ▲/▼ markers optionally call out the exact bar where a full bullish or bearish stack first appears.

#### Inputs

* **Moving-average type** – *EMA* or *SMA*
* **Fast / Mid / Slow lengths** – default 21 / 50 / 200
* **Ribbon colours** – bullish, bearish, neutral
* **Opacity (stacked / mixed)** – adjust how strong the fills appear
* **Line colours** – fast, mid, slow

#### Typical uses

1. **Trend confirmation** – Trade only when the ribbon is vivid green (long) or red (short) to filter whipsaws.
2. **Early warning** – Mixed fills flag potential transitions before a full MA cross completes.
3. **Dynamic S/R** – Each MA can act as a moving support or resistance level.
4. **Multi-time-frame stacking** – Apply the ribbon to higher TFs (e.g., 4 h) while trading lower ones for structural bias.

#### Tips

* Short-term traders might prefer 9-21-55 lengths; long-term swing traders often use 20-50-200.
* If price chops sideways, the gaps will flip soft green/red frequently—treat this as a signal to stay patient.
* Combine with volume or momentum oscillators for added confirmation.
