Method Details

Creates a 'Market' object, which accesses quotes for various ticker symbols through Ticker object

No args or keywords needed.

If 'symbol' is an index, returns an Index object for that index symbol.

If 'symbol' is an individual stock symbol, then returns a Ticker object for that stock

Fetches all history for all known stocks

This can take an hour or more, even with a broadband connection, and will leave you with a cache file of over 100MB.

You must call this before invoking Market.updateHistory

If you're only interested in specific stocks or indexes, you might prefer to invoke Index.fetchHistory or Ticker.FetchHistory, respectively.

loads all index components.

The first time this method is executed, it will download a list of component stocks for each index and store them in the database.

Subsequent calls to this method, even in future sessions, will just load these component stock lists from the database

Updates all known stocks' histories. Don't run this unless you have previously invoked Market.fetchHistory
