Stock Analysis: Automatic value prediction and alertingThe input to this workflow is a list of stock symbols from Yahoo Finance. After some preprocessing to determine the date range, this information is sent to the pandas webreader library (through the Python Source node) to collect (near) realtime stock information.The information is sent to the modeling workflow (through the Call Workflow node) where feature creation, model estimation, and prediction takes place for each stock symbol. This workflow collects the predictions and the reliability of the model, and visually displays the results - the expected percentagechange in value for each stock symbol.Note: To use this workflow you need to have Python and the following libraries installed on your machine:-pandas as pd-pandas-datareader-datetime This section creates the workflow variables that are sent to the Python Source node The workflow variables are sent to the Python Source node, which gathers historical data for each symbol. It can occur that data for a specific symbol is (temporarily) unavailable, in which case a value of -99 is returned. These cases are sent to the bottom port of theIf Switch node and are filtered out after the Loop End node. The predicted increased in stock value is sorted and exported to a plot and .csv files.When deployed on KNIME server, the Send Email node can be used to alert traders of potential interesting stock developments on a dailybasis. Authentication is supported via workflow or node level credentials; connection security via STARTTLS and SSL are both supported.
