Backtesting Profitable EAs on Multiple Computers

New comment
 
I have had lots of problems with the backtesting in Metatrader and I have asked around. It seems that everyone in the community is having the same reliability problem; hence, Metaquotes needs to address this issue. For instance I only trade the Euro and have designed 6 EAs using 6 different trading techniques. The majorities of my EAs do not use an averaging or technical indicator as they are too prompt to curve fitting during optimization and would fail during live trading. I would test my 6 EAs on 3 different computers and would get completely different results even when the 3 computers are using the same imported 1min historical data with 90% model quality.

...... Computer A ...... Computer B ... ... Computer C
EA1 very profitable... No good ............. very profitable
EA2 very profitable... very profitable........ No good
EA3 very profitable... No good ......... .... No good
EA4 very profitable... very profitable ......... No good
EA5 very profitable... very profitable ........ . No good
EA6 very profitable... No good ....... ..... very profitable

Note: very profitable is defined as profit to loss ratio of 5:1, for instance my stoploss would be 10pips and my limit would be 50pips. No good is defined as money losing EA. How is it possible to be very profitable on one computer, and then not profitable at all but then 100% correllation on another EA?

I am quite confidence in the data as I have exported the data onto a 4th computer and got the following results:

...... Computer A ...... Computer B ... ... Computer C ...... Computer D
EA1 very profitable... No good ............. very profitable...... Very Profitable
EA2 very profitable... very profitable........ No good............. Very Profitable
EA3 very profitable... No good ......... .... No good................Very Profitable
EA4 very profitable... very profitable ......... No good............Very Profitable
EA5 very profitable... very profitable ...... . No good.............Very Profitable
EA6 very profitable... No good ....... ..... very profitable..........No Good

From the above tests, 4 out of 6 EAs are profitable on 3 computers and only 2 EAs are only profitable on 2 computers. I am now certain that Strategic Tester is not stable. Have you guys ran across any profitable EAs that you can test on multiple computers? BTW, most of my EAs are on the 1hour chart; hence, the 1min data should make the strategic tester quite stable.
 
Please expose tester reports without trade list

but there is too hard to analyze such text, but there is possible
 
Hi, all six of my EAs are giving similar report like this one below with modelling quality approx 89.9% or better. Max drawdown is less than 1000 and total net profit is better than 5000. It is so strange that from computer to computer, some of the EAs yield the similar result; whereas, other EAs would fail miserably. Any clues??? One of you must have tested your EAs on more than one computer?
