For IB, according to http://www.interactivebrokers.com/php/apiUsersGuide/apiguide/api/historical_data_limitations.htm it seems you can download only a max of 2 days worth of 1-min data. It's a relatively cheap option though, if you're looking to populate your own database going forward instead of downloading years of historical data at one shot.
Hello, if someone is willing to open his big pockets, I Need 1 Minute Data for Futures for all non-US and non-German exchanges (because I allready have this) for best 10 years back (e.g. London, Korea, Singapore, rest of europe, etc.). Only interested in Futures, would be helpfull to have continious contracts as well as the genuie chains. I am willing to pay (realistic amounts) or swap one of my strategies in Exchange.
