How to Access Yahoo Finance YQL query with historical data

Question

I\'m new to YQL. Perhaps this is very trivial, but I couldn\'t quite figure this out. I know, for instance, how to query current stock data from Yahoo/YQL using the YQL cons

Answer 1

You're using the wrong table.

select * from yahoo.finance.historicaldata where symbol = "YHOO" and startDate = "2009-09-11" and endDate = "2010-03-10"

Alternatively, you could use stockretriever.py for this. In the source code, you can find a workaround for historical data.

Answer 2

The table is correct. You need to append the store parameter in your query string. Here is the sample string.

Hope it helps you.

Answer 3

yahoo.finance.historicaldata is working, but you have to use startDate and endDate:

select * from yahoo.finance.historicaldata where symbol in ("YHOO","AAPL","GOOG","MSFT") and startDate = "2012-09-13" and endDate = "2012-09-13"
