Class YahooFinanceInputSynapse

java.lang.Object

org.joone.engine.Synapse

org.joone.io.StreamInputSynapse

org.joone.io.YahooFinanceInputSynapse

All Implemented Interfaces:

java.io.Serializable, InputPatternListener, Learnable, LearnableSynapse, NeuralElement, OutputPatternListener, Inspectable, InputSynapse, PlugInListener

public class YahooFinanceInputSynapse
extends StreamInputSynapse

The YahooFinanceInputSynapse provides support for financial data input from financial markets. The synapse contacts YahooFinance services and downloads historical data for the chosen symbol and date range. Finally the data is presented to the network in reverse date order i.e oldest first.

This synapse provides the following info ..

Open as column 1

High as column 2

Low as column 3

Close as column 4.

Volume as column 5.

Adj.Close as column 6.

For the particular stock symbol.

Developer Notes :

This YahooFinanceInputSynapse uses the following format to extract stock financial information from the Yahoo Network

.

http://table.finance.yahoo.com/table.csv?a=8&b=1&c=2002&d=11&e=3&f=2002&s=tsco.l&y=0&g=d&ignore=.csv

a = From Month 0 - 11

b = From Day 1-31

c = From Year XXXX

d = To Month 0-11

e = To Day 1-31

f = To Year XXXX

s = Symbol

y = [record] from record to + 200 records

g=[d] or[m] or [y] - daily or monthly or yearly

ignore = .csv
