## Ejemplo
|
|
|
|
```python
|
|
prices = [10, 11, 12, 13, 14, 15]
|
|
result = ema(prices, 3)
|
|
# [11.0, 11.5, 12.25, 13.125]
|
|
```
|
|
|
|
## Notas
|
|
|
|
El primer valor de la EMA es el SMA del primer periodo. El multiplicador es 2 / (period + 1).
|
|
Retorna len(data) - period + 1 elementos. Lista vacia si period invalido.
