ema
Calculate the Exponential Moving Average (EMA).
EMA is a cumulative calculation, including all data. Past values have a diminishing contribution to the average, while more recent values have a greater contribution. This method allows the moving average to be more responsive to changes in the data.
Example:
from openbb import obb
stock_data = obb.equity.price.historical(symbol="TSLA", start_date="2023-01-01", provider="fmp")
ema_data = obb.technical.ema(data=stock_data.results, target="close", length=50, offset=0)
