Parameter Description

symbol	A valid U.S. stock symbol to look for the corresponding UpcomingSplit object
dt	Date used to determine if a stock splits on given date
provider	(Optional) Choice of source for upcoming split data: query All the 4 providers, query Fidelity / Yahoo / Briefing / Nasdaq separately

Description

Builds a database of U.S. stocks that are about to split in the upcoming month using Fidelity, Yahoo as the primary data source or Nasdaq and Briefing as backup data sources (should Yahoo fail for whatever reason). To download and to cache the data in an XML file in Wealth-Lab's AppData directory, DeSerialize. On the first call, there's a slight delay while the data is being downloaded from the web service. Subsequent calls are instant provided that the cache exists. If the stored data is older than 1 day, on next call it will be automatically refreshed.

Since v2020.09 it's possible to extend the number of collected splits by quering all the 4 providers, or have a choice to target specific source (Fidelity, Yahoo, Briefing or Nasdaq). If this is not specified (default behavior), the class will start with Fidelity and fall back to the other sources on failure.

An instance of the UpcomingSplit class contains the following properties for U.S. stocks: payable, ex-date, company, symbol, ratio and announcement date. Before calling the FindSymbol method with a stock symbol to return an instance of UpcomingSplit, call DeSerialize to avoid delays caused by refreshing the data from the internet.

To determine if stock splits on given date, call IsStockSplit. To determine the split factor for a given stock on given date, use SplitFactor.

Finally, the complete classification of all stocks about to split is accessible in the Splits property.
