Price Forecast Data

How it works: Models are based on Facebook's Prophet. Hyperparameters are pre-set. Historical data for the selected ticker is fetched from Alpha Vantage, log-transformed, and used to fit the model. Predictions are then exponentiated back to the original price scale. Fetched data is cached daily in the Space's temporary storage to minimize Alpha Vantage API calls and speed up subsequent requests for the same ticker on the same day.
