The script retrieves historical closing-price data for NVDA and VUAA.AS directly from Yahoo Finance.
First tab displays a candlestick chart for the selected time range. Two Simple Moving Averages are calculated automatically; their periods adapt to the chosen interval (for example SMA 5/10 on short ranges and SMA 50/200 on longer ones) and are shown in the legend. Clear dates appear on the horizontal axis.Its second tab, ML Predictions, focuses on statistical modelling. The downloaded series is fitted with three algorithms: ordinary linear regression, polynomial regression (degree adjustable by the user), and a Random Forest regressor. All four lines—the original prices plus the three model outputs—are plotted on a single chart. Clear calendar dates appear on the horizontal axis, and an enlarged legend identifies each curve. Loading feedback is shown while data are fetched. The tab therefore converts raw Yahoo price history into immediate visual comparisons of linear, non-linear and ensemble trend estimates.
