I'm not able to backtest a strategy more than about 4 weeks. I use interactive brokers and when I d'like to backtest a strategy (15 Minute - Bars), there always pops up a window after a couple of seconds with the message, that the data can not be loaded, because there is an IB restriction to load the data. I tried it several times, but there is always the same problem.
Can someone help?
