Hello Ionene,
In fact, this behavior that you have mentioned on your post is just ONE of the possible scenarios of results that a trader may have since the moment that an account is initiated with a Sytlas EA working overthere.
In my vision, this situation of having possible different performance scenarios was expected, simply based on the kind of Strategy developed and gently shared by Symphoenix: the Sytlas is based in the correlations between all the 8 currencies and, consequently, the PARITY existent between the 28 currency pairs at the moment that the EA is being initiated and, consequently, the performance that will be generated from that moment on will be impacted by many factors.
Believe me, I had cases that I initiated two trading accounts with Sytlas, at the same Broker, VPS, parameters, etc, but with a difference of just two hours, and the results of these two accounts are being completely different.
And even upon this characteristic of being "unprecitable" and or "chaotic" this behavior of the EA may be interesting, of course depending on the creativity and capacity of the trader in dealing with this.
My percepction is that the Sytlas EA is a very promising concept but, as Symphoenix has mentioned previously, as everything in this World, there are allways room for improvement.
As an Old Master of the "Forex Algorithmic Trading" told a few years ago...
"Much more important than the POWER of the EA itself, is the WAY that the Trader develops to use it and achieve consistent profits."
Best Regards,
