Commercial EA's

Hi guys I am looking for a new EA to add to my account are there any recommendations? I have no objection paying for one providing the evidence is there that it works!

Hi, i use a lot of EAS:
Wall Street forex robot (which is very well known)
Volatility factor (which is also well known specially from when is available in the Autotrade section of Myfxbook)
Forex Diamond
Forex Scalpino robot
Hyper EA 2.4
I have good opinions on all of these, but i think the best one is Forex Diamond!
