Backtest Data

 

Can any one tell me where can I buy data to back test with 99.9% quality?

I need to test some EAs before purchasing.

Thank you.

about 99.9% backtesting ... so make sure that the broker is having this data (because you will trade by the EA using the data provided by the broker, and they are not 99.9% ...).
