Different Results on the Performance Tests of the same Program, Why?

[Forex88]

Hi,

I wonder, same program shows very different results (even on the same periods) on performance test regarding the profit % per month, maximal Draw Down and other measures.

E.g. Million Dollar Pips show very high profits at the Demo Test at ForexVerified.com:

While it shows lower results at the Demo test at Forex Peac Army, and even Lower result at the Live test at FPA.

Again it shows high results at the Demo Test at MyFXBook.com.

What can be the reasons that performance tests show different results on the same program, and even on the same periods?


Or I'm very bad at reading these tests?

Results from the same EA running at the same time can vary for several reasons...

1. Demo vs. Live accounts. Demos are less likely to get slippage and requotes.

2. Different brokers can have different data feeds.

3. The same broker may have different MT4 servers.

4. Connection speed between the computers running the EA and the MT4 server.


Demo vs. Live is one of the biggest factors. This is one of the reasons the FPA phased out all demo testing years ago. The old demo test results are retained, but all of those tests were stopped.
