This review is about the Primeval-EA.
I have no affiliation with anyone in conjunction with this review.
I started trading this EA on a demo account on March 10, 2010. Primeval-EA trades 8 pairs on an M15 chart. The demo account is with Alpari UK at 500:1
leverage 
.
The EA purchase goes through Plimus which has a 45 day refund policy. This EA is expensive at $500. If you look around, you can find affiliates that
offer 
a Paypal credit back to your account after the 45 day refund period. I purchased the EA through the
ForexOZ affiliate. Mark at ForexOZ promises $50 back if you buy through his affiliate link.
The EA comes with a
dll and requires authentication similiar to MegaDroid. You are limited to 10 demo accounts and 1 live account (although the license terms allow a special bonus live account). Each account you plan to use must be setup in the online
member zone. Any refund request is denied if you activate a live account.
The software package is delivered as Windows installer
exe. You don't have to copy any files. All the files are placed into the Metatrader folder for you. As an interesting bonus, the EA comes with a template and indicators so that you can see what is going on and trade the strategy manually if you desire.
I
rate 
the email support as excellent. After my purchase, I encountered two problems. The first was that I was not redirected properly after the purchase to create a member account on the Primeval-EA website. I emailed support who within minutes created a member account for me. The second issue was that when I attempted to download the Windows installer, I was getting a Php/Javascript server error. Once again, I emailed support. This time it took the support staff some hours to get back to me but before the day was over, I was able to download the software.
This EA trades EURUSD, GBPUSD, EURGBP, USDCHF, EURCHF, GBPCHF, USDCAD, USDJPY using three specific strategies:
Scalping
Grid
Hedging
The setup is complex and time consuming because the EA has many settings, the license requires authentication and there are many charts to setup (10 of them in total). Here is the way I set my Primeval-EA:
All settings I left at the default except:
MinLots: 0.10
MaxLots: 50
RiskLevel: see below
SoundAlert: false
An obvious missing parameter is one that controls the magic. With this many charts, a way to segregate the trades besides the
currency pair 
is important. I have no idea at this
point 
how I am going to manage all the closed trades and do a proper analysis.
Scalping Strategy (currency pair followed by RiskLevel):
GBPUSD 10
EURUSD 15
EURCHF 30
EURGBP 20
USDCHF 15
USDCAD 15
USDJPY 15
GBPCHF 15
Grid Strategy:
EURCHF 20
Hedging & Pyramiding Strategy:
GBPUSD 10
