On the MQL5 site among the most reliable signal providers there are many results showing 500% to 1000% profit per year for several years, even though they only have a 100 or 200 subscribers. This should be a legitimate site but I can't believe the figures actually exist. Other sites claim figures that also seem unachievable. What is really happening here? By comparison Myfxbook's most successful traders are showing an honest 1-2% per month.
