It's the age-old story on MyFXBook. When someone starts with 'I made whatever%' in 'whatever number of days/weeks/months', then you know its bullshit. Signal services are a load of crap. And if any retail trader can claims that he/she made '1480% in just 4 weeks'... then he/she is a 1400% more profitable than Institutional Traders (Banks, Hedge-funds, etc.), HFT Traders (who has the fastest and best equipment and software a few million dollars can buy) and the best minds in trading in the world.
If you have to resort to providing 'Trade Signals', selling indicators, EA's and all sorts of trading systems, then you simply have failed as a trader and the only way to make money left in the trading industry is to provide all sorts of bullshit services to unsuspecting new traders.
Don't get me wrong, EA's can make money, some well developed trading systems make money, some indicators can HELP you make reasonably good trading decisions... but then why would a consistently successful trader (talking about the few who make realistic profits, 3-5% pm, over a long period) sell his/her system, EA or indicator to the competition?
In my opinion, if you are really serious about making trading your profession, go and learn how the market you trade REALLY works. Develop your OWN system, trading method, EA, Algo or Indicator that works for you and above all, have realistic expectation about your long term profits. Claims like 30%pm/ is rubbish.... prove to me you can do that over a period of 6 months, a year or better yet 3 years, consistently without blowing up your account.
These are my own personal opinions, and I welcome anyone who can REALLY prove me otherwise... I think after 7 years of hard work as a trader, really learning how markets work, are structured, what price action REALLY is, etc. (and I still have my day job as a programmer) I got to know the difference between bullshit and reality...
Keep it simple, be disciplined, get rich slowly and above all protect your equity!
