I'm looking for some intraday stock data. Doesn't really matter what kind of security... I'm just looking for price, volume, bid, and ask. I'm looking to test a model based on the dynamics and kinematics of a body and how it can be applied to stock price movement, however I have no source of sample data to test on. I don't feel the need to purchase any data because I'm not looking for huge quantities... Only a small amount to test on, perhaps just a day's worth, doesn't even matter from what date.
Any source of such sample data? Or should I write up a data scraper and just run it for a week to get this data?
Here is a link to a research publication that models stock movement from Newton's Second Law of motion: http://apmr.management.ncku.edu.tw/comm/updown/DW0904222241.pdf
