target_column	str	Target column to forecast. Defaults to "close".	close	True
n_predict	int	Days to predict. Defaults to 5.	5	True
train_split	float	Train/val split. Defaults to 0.85.	0.85	True
past_covariates	str	Multiple secondary columns to factor in when forecasting. Defaults to None.	None	True
forecast_horizon	int	Forecast horizon when performing historical forecasting. Defaults to 5.	5	True
