I've been considering trading some of the Euronext (Liffe) contracts through IB but can't locate a source for historic EOD or intraday data. On the Euronext web site there is mention of data available, but not very clear how it is presented. And the cost is astronomical, like 600-900 euros per year of data. Perhaps I'm misunderstanding. Anyway, any tips on a good data source. I need a lot of intraday. For US markets Tradestation is only convenient source I found. Esignal only goes back 6 months I believe. Suggestions?
