The most typical cause of not seeing 99% modelling quality is that you have not launched your Metatrader via Tickstory.
The other things to check are:
Have you accidentally exported to a different directory than you are launching from?
Are you back-testing a symbol that should be mapped? For example, is your MT4 using “EURUSDm” rather than “EURUSD”? (Consult the manual for further details on how to do this)
