Where get clean data for backtesting

[mrbeanbag]

Hello, I have been working hard on creating profitable strategies, I can get some good results but when I go back and look at the charts I see that the biggest profits are coming from bogus trades due to data gaps.

Can anyone recommend where I can get good clean downloadable tick data for EUR/USD (or any other would be fine)?

I'm with IB and I'm slowly building up somewhat clean useable data but IB doesn't allow 24hr connection so it logs itself out every 12 hours unless I reset it every time. This is a problem.

Thanks very much.

IB Re-Connect

Hi,
There is a application I use to restart IB automatically so it really is not off very long
