Tri-Align Crypto Trend (EMA + Slope)

**Tri-Align Crypto Trend (EMA + Slope)**

Quickly see whether your coin is trending *with* Bitcoin. The indicator evaluates three pairs—**COIN/USDT**, **BTC/USDT**, and **COIN/BTC**—using a fast/slow EMA crossover plus the fast EMA’s slope. Each pair is tagged **Bullish / Bearish / Neutral** in a compact, color-coded table. Alerts fire when **all three** trends align (all bullish or all bearish).

**How to use**

1. Add the indicator to any crypto chart.
2. Set the three symbols (defaults: BNB/USDT, BTC/USDT, BNB/BTC) and optionally choose a signal timeframe.
3. Tune **Fast EMA**, **Slow EMA**, **Slope Lookback**, and **Min |Slope| %** to filter noise and require stronger momentum.
4. Create alerts: *Add alert →* choose the indicator and select **All Three Bullish**, **All Three Bearish**, or **All Three Aligned**.

**Logic**

* Bullish: `EMA_fast > EMA_slow` **and** fast EMA slope ≥ threshold
* Bearish: `EMA_fast < EMA_slow` **and** fast EMA slope ≤ −threshold
* Otherwise: Neutral

Tip: The **COIN/BTC** row reflects relative strength vs BTC—use it to avoid chasing coins that lag the benchmark. (For educational purposes; not financial advice.)

**Tri-Align Crypto Trend (EMA + Slope + Strength)**

**What it does**
Checks whether your coin trends *with* Bitcoin by evaluating three pairs—**COIN/USDT**, **BTC/USDT**, **COIN/BTC**—on a chosen signal timeframe. Each pair is classified by fast/slow EMA structure **and** slope, shown in a compact table with a **Trend** label and a **Strength %** index. Alerts fire when all three pairs align (optionally only when they’re strong).

### Trend labels (how the regime is determined)

Let `F` = fast EMA, `S` = slow EMA; `sf`/`ss` = slopes of `F`/`S` over `slopeLen`.
Slopes are **positive / flat / negative** using a threshold `slopeThrPct`.

**Bull stack (F > S)**

* **Bull Acceleration**: `sf ↑` & `ss ↑`
* **Bull Pullback**: `sf ↓` & `ss ↑`
* **Bull Compression / Topping Risk**: `sf ↓` & `ss ↓`
* **Bull Re-ignite (Opposite)**: `sf ↑` & `ss ↓`
* **Bull Range-Above**: both flat

**Bear stack (F < S)**

* **Bear Acceleration**: `sf ↓` & `ss ↓`
* **Bear Rally (Countertrend)**: `sf ↑` & `ss ↓`
* **Bear Compression / Bottoming Risk**: `sf ↑` & `ss ↑`
* **Bear Re-assert (Opposite)**: `sf ↓` & `ss ↑`
* **Bear Range-Below**: both flat

For quick reading, the Trend cell is also color-coded: **green = bullish**, **red = bearish**, **yellow = neutral/transition** (pullbacks, rallies, ranges, compressions).

---

### Strength % (what the number means)

A **signed intensity score** for the current trend:

* **Positive** = bullish intensity, **Negative** = bearish intensity, **0%** = neutral/flat.
* Computed from two intuitive pieces (weights adjustable):

* **EMA gap %**: `100 * (F − S) / S` → structure
* **Fast EMA slope %**: `100 * (F − F[n]) / F` → momentum
* Composite (default): `wGap * |Gap%| + (1 − wGap) * |Slope%|`
Optional: **ATR-normalize** by `%ATR = 100 * ATR / close` to make values comparable across volatile pairs.

The **Strength** column shows this signed composite (rounded, with a heatmap background).

---

### Inputs (key)

Symbols, signal timeframe, `Fast/Slow EMA`, `Slope Lookback`, `Min |Slope| %`, plus strength controls: `Weight Gap`, `ATR-normalize`, `ATR Length`, and `Min |Strength|` for strong-alignment alerts.

---

### Alerts

* **All Three Bullish / Bearish**
* **All Three Aligned (Bull or Bear)**
* **All Aligned + Strong**: alignment **and** each row’s `|Strength| ≥ Min |Strength|`.

**Tip:** Watch **COIN/BTC** to gauge relative strength vs BTC; require **Aligned + Strong** to filter weak, low-quality moves.
