+# ADX: Average Directional Index
 
 The Average Directional Index is the industry-standard measure of trend strength, ignoring direction entirely to focus on the velocity of price expansion. Wilder's pipeline decomposes range into directional movement (+DM, -DM), normalizes against True Range to produce directional indicators (+DI, -DI), derives a directional index (DX) from their ratio, then smooths DX with a final RMA pass. The double-smoothed architecture creates significant lag but exceptional noise rejection, making ADX a regime filter rather than a timing tool. Output is unbounded above 0, with readings above 25 conventionally indicating trending conditions and below 20 indicating choppy markets.

The core directional movement logic (+DM, -DM, True Range) is preserved faithfully from Wilder, but the three parallel smoothing passes use JMA's adaptive bandwidth instead of RMA's fixed $\alpha = 1/N$. The result is a directional indicator that reacts 3-5 bars earlier to trend changes than standard DMI while filtering out more noise during consolidation. Output is the difference between smoothed directional indicators: $DMX = DI^+ - DI^-$, positive for uptrends and negative for downtrends.

+# DX: Directional Movement Index
 
 The Directional Movement Index is the raw, unsmoothed measure of trend strength from Wilder's directional movement system. It decomposes price expansion into +DM and -DM, normalizes against True Range using RMA smoothing to produce +DI and -DI, then computes the ratio $DX = 100 \times |{+DI - {-DI}}| / ({+DI + {-DI}})$. Unlike ADX, which applies a final RMA pass to DX, the raw DX responds immediately to changes in directional dominance — making it noisier but approximately one full period faster. Output ranges from 0 to 100, where high values indicate strong directional movement regardless of up/down direction. DX is the building block from which ADX is derived.

 The Hilbert Transform Trend Mode indicator is a binary regime classifier that determines whether price action is dominated by trending behavior (output = 1) or cyclical/mean-reverting behavior (output = 0). It uses the full Ehlers Hilbert Transform pipeline — 4-bar WMA smoothing, Hilbert FIR filters, homodyne discriminator for period estimation, DC phase extraction, and SineWave indicators — then applies four decision criteria to classify the current regime. The implementation follows TA-Lib's Ehlers-faithful algorithm from the February 2002 publication. Output is discrete {0, 1}, making it a direct strategy selector: deploy trend-following logic when mode = 1, and mean-reversion logic when mode = 0.

Senkou Span A and B form the "cloud" (Kumo) — a projected equilibrium zone displaced forward in time. Chikou Span is simply the current close displaced backward.

+## Performance Profile
+
+### Operation Count (Streaming Mode)
+
+Vortex tracks rolling sums of VM+ and VM− (directional bar movements) and TR over N bars using O(1) running sums backed by RingBuffers.
+
+**Post-warmup steady state (per bar):**
+
+| Operation | Count | Cost (cycles) | Subtotal |
+| :--- | :---: | :---: | :---: |
+| ABS × 2 (VM+ = |High − PrevLow|, VM− = |Low − PrevHigh|) | 2 | 1 | 2 |
+| TR computation (SUB×3, ABS×2, MAX×2) | 7 | 1 | 7 |
+| SUB × 3 (subtract oldest from sums) | 3 | 1 | 3 |
+| ADD × 3 (add new to sums) | 3 | 1 | 3 |
+| RingBuffer writes × 3 | 3 | 1 | 3 |
+| DIV × 2 (VI+ = sumVM+/sumTR, VI− = sumVM−/sumTR) | 2 | 15 | 30 |
+| CMP (sumTR > 0 guard) | 1 | 1 | 1 |
+| **Total** | **21** | — | **~49 cycles** |
+
+Three parallel O(1) running sums with RingBuffers. For default $N=14$: ~49 cycles per bar. Batch mode pre-computes per-bar vectors then applies sliding sums.
+
+### Batch Mode (SIMD Analysis)
+
+| Operation | Vectorizable? | Notes |
+| :--- | :---: | :--- |
+| VM+ / VM− computation | Yes | VSUBPD + VABSPD — fully independent per bar |
+| TR computation | Yes | VSUBPD + VABSPD + VMAXPD — independent per bar |
+| Prefix sum (VM+, VM−, TR) | Partial | Inclusive prefix sum; SIMD assist with subtract-lag |
+| Division (VI+, VI−) | Yes | VDIVPD on prefix-sum results |
+
+All individual-bar computations are independent and SIMD-friendly. The prefix-sum step benefits from AVX2 vectorization. For $N=14$ and arrays of 1000+ bars, batch SIMD achieves ~3–4× throughput over scalar streaming.
+
+### Quality Metrics
+
+| Metric | Score | Notes |
+| :--- | :---: | :--- |
+| **Accuracy** | 10/10 | Exact arithmetic; O(1) running sums avoid floating-point drift |
+| **Timeliness** | 7/10 | N-bar window; responds within one period to directional change |
+| **Smoothness** | 6/10 | Rolling sum provides moderate smoothing; no additional filter |
+| **Noise Rejection** | 6/10 | N-period window averages out individual bar noise; no adaptive bandwidth |
