Mastereas.com is legit and I have purchased its product for about 4 months. I have been using Price Action Scalping EA on my live account for the past 4 months. This is a powerful product and the support is excellent. With default setting of 100% accuracy, it trades up to 2-3 days per week. Impressed, everything has worked as I expected which is shocking from previous robots I've tried that did nothing but lose money. The forum is also full of wealthy information.
There really isn't anything bad I can say about Mastereas.com and there EA at this time, I will update this review if anything changes.
