## Performance Profile
### Operation Count (Streaming Mode)
ADOSC = short EMA of ADL minus long EMA of ADL. Two parallel EMA updates per bar — O(1).
| Operation | Count | Cost (cycles) | Subtotal |
| :--- | :---: | :---: | :---: |
| ADL accumulation (MFM * Vol) | 1 | 8 cy | ~8 cy |
| Short EMA update (FMA) | 1 | 1 cy | ~1 cy |
| Long EMA update (FMA) | 1 | 1 cy | ~1 cy |
| ADOSC = shortEMA - longEMA | 1 | 1 cy | ~1 cy |
| NaN guard + state update | 1 | 2 cy | ~2 cy |
| **Total** | **O(1)** | — | **~13 cy** |
O(1) per bar. Two EMA states maintained in parallel. After warmup (longPeriod bars), both EMAs are hot. FMA used for EMA update: new = FMA(prev, decay, alpha*adl).
ADOSC is slightly heavier than ADL because it involves two EMAs.
