I need to ask you if you are 100% sure that you get 90% quality when backtesting? The reason i ask is that when downloading history from metaquotes which is the case for most brokers, including Alpari UK, you will recive huge gaps in the data. The most recent gap is on EURUSD between 2010 05 07 - 2010 06 24.
I have attached 2 pictures. Both on XBars. I have used the 1.03 version and the set file you provided in the first post.
The first picture shows backtesting on Alpari 2007-01-01 to 2010-06-25. Here i have even asked Alpari to provide me with the missing tick data, and they did.
A great result
How ever... Alpari and every other broker for that matter isn't going to sit down and look for the gap for you. I you will most defently not notice every missing tick.
The second picture shows the exact same period of testing and set file. Only here i have recived tick data from a friend of mine that have downloaded it from his broker which provide this data for it's customers.
And yes i am aware of that the result will differ from broker to broker. But hardly not with over 100 000 USD.
So my question to you Funyoo is: What tick data do you use and how reliable is it?
