No doubt, a good algorithm, a good expert advisor is a very useful thing. Automatical trading could be much helpful. But any machine does only the things a person tells it to do in such and such circumstances and situations. Nothing more. So it would win money when you would yourself and lose it when you would yourself, becourse it is the algorithm you wrote. So still I would stipulate that a good trader is a profy, never a gambler, but an extremely well educated generally and financially, firmly understanding that money management is the fundamental aspect of safe trading, feeling the pulse of the market and having developed a profitable strategy. Only having all of this components assembled one can write an algorithm to earn money. I use automatical trading as well as manual and find it much more interesting then using them separately.
everything is very simple, you just have to guess
