I spent $1000's on Indicators, Signals and EA's since I started this Forex journey a couple of months ago. One thing I figured out that if a seller of anything is promoting their products/services through Affiliates, then the service is a scam. Scam may not mean illegal. But it does mean that the product or service doesn't work as advertised. If it did, the developer would not need to pay people to sell the product.
If you see something that doesn't look right, share the information. I am tired of people getting ripped off.
Best example is GPS 3 EA. Complete scam!
