## Performance Profile
### Operation Count (Streaming Mode)
ADL computes Money Flow Multiplier (MFM) from bar data, multiplies by volume, and accumulates cumulatively — O(1).
| Operation | Count | Cost (cycles) | Subtotal |
| :--- | :---: | :---: | :---: |
| MFM = ((C-L)-(H-C)) / (H-L) | 1 | 5 cy | ~5 cy |
| MFV = MFM * Volume | 1 | 3 cy | ~3 cy |
| ADL += MFV (cumulative sum) | 1 | 1 cy | ~1 cy |
| Zero guard on H-L | 1 | 2 cy | ~2 cy |
| NaN guard + state update | 1 | 2 cy | ~2 cy |
| **Total** | **O(1)** | — | **~13 cy** |
O(1) cumulative indicator — no window, no buffer. Throughput ~4 ns/bar. Division is the critical path (H-L guard prevents divide-by-zero on doji bars).
| Metric | Score | Notes |
| :--- | :--- | :--- |
| **Throughput** | 10 | High; O(1) calculation with simple arithmetic. |
