 Ichimoku Kinko Hyo ("One Glance Equilibrium Chart") is a comprehensive trend-following system that provides five distinct components revealing trend direction, momentum, support/resistance levels, and potential future price zones simultaneously. The Tenkan-sen and Kijun-sen are midpoints of high-low ranges at different timescales (not moving averages of closes). 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. All components use sliding window min/max arithmetic, producing step-function behavior on breakouts rather than the smooth curves of EMA-based systems. The system requires OHLC bar input.

 The indicator produces five simultaneous values per bar. The primary output (`Last`) returns Kijun-sen as the default reference line.
 
+## Performance Profile
+
+### Operation Count (Streaming Mode)
+
+Ichimoku draws five lines from three sliding window min/max operations and two EMA values for the Cloud. Three RingBuffers track highs/lows for Tenkan (9), Kijun (26), and Senkou B (52).
+
+**Post-warmup steady state (per bar):**
+
+| Operation | Count | Cost (cycles) | Subtotal |
+| :--- | :---: | :---: | :---: |
+| RingBuffer updates × 3 (T/K/S highs+lows) | 6 | 1 | 6 |
+| Window max/min scans × 3 pairs (amortized O(1) with deques) | 6 | 1 | 6 |
+| ADD + MUL×0.5 × 3 (midpoints for T, K, SB) | 6 | 3 | 18 |
+| ADD + MUL×0.5 (Senkou A = (T+K)/2) | 2 | 3 | 6 |
+| ADD + MUL×0.5 (Chikou = close[26]) | 2 | 1 | 2 |
+| Buffer shift reads × 2 (Senkou A/B lag 26) | 2 | 1 | 2 |
+| **Total** | **24** | — | **~40 cycles** |
+
+Five output lines, three window scans, two lag buffers. For default periods (9/26/52): ~40 cycles per bar at steady state.
+
+### Batch Mode (SIMD Analysis)
+
+| Operation | Vectorizable? | Notes |
+| :--- | :---: | :--- |
+| Sliding max/min (3 windows) | Partial | Lemire deque O(n) total; scan phase SIMD-friendly |
+| Midpoint arithmetic | Yes | VADDPD + VMULPD (×0.5) |
+| Lag buffer reads | Yes | Array offset memory access |
+
+Three independent window extremum computations can be parallelized. The midpoint and lag arithmetic is trivially vectorizable.
+
+### Quality Metrics
+
+| Metric | Score | Notes |
+| :--- | :---: | :--- |
+| **Accuracy** | 10/10 | Exact integer-position midpoints; no floating-point drift |
+| **Timeliness** | 3/10 | Senkou B requires 52-bar window + 26-bar projection = 78 bars to stability |
+| **Smoothness** | 7/10 | Midpoint lines are inherently smooth; Cloud edges can gap |
+| **Noise Rejection** | 7/10 | Window midpoints average out bar-to-bar noise by construction |
