EA Backtest question

 

Hi Guys


I need to backtest an EA. Now there are different methods in MT4 I need to have realy exact data so i choose "tick", but can you tell me, how exact this data feed really is? Are there many mistakes in the data or is it OK? Is really every tick in the feed? I also need a store to buy updated Forex data, in case the Data from MT4 is not exact enough. the data should not be older than 2 Weeks. You know a place to buy? Thank you very much for the answers!
