## Performance Profile
| Metric | Score | Notes |
| :--- | :--- | :--- |
| **Throughput** | 9 | High; O(1) calculation with 3 EMA steps. |
| **Allocations** | 0 | Zero-allocation in hot paths. |
| **Complexity** | O(1) | Constant time regardless of period. |
| **Accuracy** | 10 | Matches TA-Lib exactly. |
| **Timeliness** | 10 | Extremely low lag; nearly zero-lag tracking. |
| **Overshoot** | 8 | Significant overshoot on sharp reversals. |
| **Smoothness** | 6 | Less smooth than SMA/EMA due to high responsiveness. |
## Validation
Validated against TA-Lib (`TA_TEMA`) and Skender.Stock.Indicators.
| Library | Status | Notes |
| :--- | :--- | :--- |
| **QuanTAlib** | ✅ | Validated. |
| **TA-Lib** | ✅ | Matches `TA_TEMA` exactly. |
| **Skender** | ✅ | Matches `GetTema` exactly. |
| **Tulip** | ✅ | Matches `tema` exactly. |
| **Ooples** | ❌ | Diverges significantly due to initialization logic. |
