My advice would be that these robots are not an end all. MegaDroid may be a good robot, and experimenting with these robots may be fun and potentialy profitable, but the most important thing you can do for yourself in this business is to learn to be an independant trader, and not to rely on robots or other people for your trading. This is a process like any other learning endevor, and can take quite a bit of time to master, and debug. There is a lot of different information available, and you are going to have to decide what fits you. But the basics of trading have never changed, the market trends, its consolidates, and it breaks out into a new move. You can trade these breakouts in the hope that they become a new
trend 
, or at least a big enough move to profit on. This is probably one of the easiest ways to trade the Forex market, and there are many inexpensive courses that go over the principles of standard breakout trading. Most of the differences between those that make money and those that dont come down to trade managment and money managment, and the ability to set and follow some rules, and not jump the gun or second guess your rules.
I really dont know what level you actualy are in your trading, but Bill Poulos, who is one of the best trading teachers I know of, has just come out with a primer for newer traders. Bill's courses are usually very expensive, and include lots of support and sets of dvd's, but this is a $100 download, and seems to have been put together very well for newer and struggling traders.
http://www.nohypeforex.com/SixForexMistakes worth taking a look at. At least link to his main site and register for his free material, it is some of the best I've read.
Other than this, there is a ton of material available. Books, courses, trading systems, etc. I would also suggest visiting the ForexPeaceArmy.com and checking the reviews. Any of the highly rated items should be worth adding to your arsenal. And dont rely to heavily on these robots or other people for your trading. This is a business like any other and you need to develop your understanding and knowledge.
