All Implemented Interfaces:

public class GPQuoteBundle
extends EODQuoteBundle

This class is a specialised version of the EODQuoteBundle tailored specifically for the GP. It differs from in that it enforces a window of dates. This window prevents the GP expressions from accessing quotes too far in the past which would slow down calculations (e.g. calculating the average value of a stock for the last 3,000 days), and also prevents GP expressions accessing quotes that would be in their future.

                throws EvaluationException,
Get a stock quote. This function has been primarily created for Gondola scripts. It passes in the current date and the date offset so that specialised QuoteBundle implementations such as GPQuoteBundle can prevent the GP accessing 'future' dates.

symbol - the stock symbol
quoteType - the quote type, one of Quote.DAY_OPEN, Quote.DAY_CLOSE, Quote.DAY_LOW, Quote.DAY_HIGH, Quote.DAY_VOLUME
today - fast access date offset of current date, see EODQuoteCache

EvaluationException - if the script isn't allowed access to the quote.

public void setQuoteRange(EODQuoteRange quoteRange)
Set the qutoe range which specifies this quote bundle.
