+# AMAT: Archer Moving Averages Trends
 
 The Archer Moving Averages Trends indicator is a triple-confirmation trend identification system that uses dual EMAs to produce discrete directional signals (+1 bullish, -1 bearish, 0 neutral). Unlike simple crossover systems that trigger on any intersection, AMAT requires alignment of three conditions: relative position (fast above/below slow), fast EMA direction (rising/falling), and slow EMA direction (rising/falling). This triple gate filters out the whipsaw endemic to single-condition crossover systems in ranging markets. A secondary output quantifies trend strength as the percentage separation between EMAs, providing a conviction metric for position sizing.

+## Performance Profile
+
+### Operation Count (Streaming Mode)
+
+AMAT compares a fast EMA against a slow EMA to determine trend direction.
+
+**Post-warmup steady state (per bar):**
+
+| Operation | Count | Cost (cycles) | Subtotal |
+| :--- | :---: | :---: | :---: |
+| FMA × 2 (fast EMA, slow EMA updates) | 2 | 4 | 8 |
+| CMP (fast > slow → trend = 1 else 0) | 1 | 1 | 1 |
+| **Total** | **3** | — | **~9 cycles** |
+
+Two independent EMA streams with a single comparison. One of the cheapest dynamics indicators: ~9 cycles per bar at steady state.
+
+### Batch Mode (SIMD Analysis)
+
+| Operation | Vectorizable? | Notes |
+| :--- | :---: | :--- |
+| EMA (fast) | **No** | Recursive IIR — sequential |
+| EMA (slow) | **No** | Recursive IIR — sequential |
+| Comparison | Yes | VCMPPD after both EMA arrays computed |
+
+Both EMA passes are recursive and sequential. The final comparison step is trivially vectorizable once both arrays exist.
+
+### Quality Metrics
+
+| Metric | Score | Notes |
+| :--- | :---: | :--- |
+| **Accuracy** | 9/10 | Exact EMA arithmetic; binary output eliminates rounding nuance |
+| **Timeliness** | 7/10 | Slow EMA period determines lag; faster than SMA-based versions |
+| **Smoothness** | 10/10 | Binary 0/1 output is maximally smooth by definition |
+| **Noise Rejection** | 7/10 | EMA crossover can whipsaw in sideways markets |
