I got the same email as hazenvnn and the same yellow warning flags he points out also went off in my head as well. I mean, any "very large Forex trading organization" (quoting Martin's email) worth their salt already knows where to seek out the best EA programmers and their EA's. Heck, just go hang out on the forums and MQL4 dot com and you'll find hundreds of them. It just doesn't add up. In this day and age, scams are a plenty so I think you have no choice but to be skeptical.

But I also agree with Neo. I'm not ready to throw the guy under the bus yet...but I am cautious. There are other forums in addition to this one that have back and forward tested his EA and Slingshot system to death and neither are very impressive long term but some recent modifications to Slingshot have shown promise. I've been running his EA non-stop since 12/31/08 and its just slightly over break even for me. I'll give it another month or two and decide to pull the plug or not. The guy hasn't done anything wrong yet that I can see but he hasn't exactly put all of his cards down on the table yet either. Only time will tell. The nice thing about the Internet is that its getting easier to background check the seller before you buy.
