NYSE Euronext contains intraday stock price data for Euronext companies.
This data is only available on an external harddisk. The data is available for researchers, but it is difficult and time consuming to retrieve the data. We advise the researcher to contact the EDSC Datateam (datateam@). ubib.eur.nl
Other information sources with intraday data are TAQ (only US companies) and Bloomberg.
