The philosophy of a Trade Machine

Source: TradeMachine.
It is a long time now that I'm playing with the idea of making a Trade Machine. I'm a novice technical trader, using technical analysis tools for making on-the-spot buy/sell decisions. There are plenty of people worldwide that are doing the same, some are more experienced and professional and some even doing it for a living. I am not doing it for a living, but wish I could, and recently circumstances made me some extra time that might help me to get closer to that dream of mine.
So [1] what is a trade machine, [2] why should I want to have one and [3] are there any on the market today?
A1: In simple, a trade machine is an investment "guru" that is programmed to identify potential opportunities in the market and perform actual trade activities in order to take advantage of these opportunities. The trade machine performs "day trading" activities in most cases. Some types of trade machines may be less proactive and more suggestive. Instead of running as "daytraders" and performing the actual buy/sell the machine can suggest you to do it and you will take the final decision. Such machines are more suited to end-of-day analysis since they are not required for on-the-spot decision (the human factor can not be assumed to act at once).
A2: Obvious. Having a trade machine that is callibrated with algorithms that works out is a money maker that no-one would like to loose. Such machine can make you financially free, leaving you the decision what to do with your time. I'm not a lazy guy, but having the option to choose is something that is rarely available ever.
A3: No one would admit it since it might motivate others to try building their own money machines. Too much machines in the market will reduce the potential profit for each one of them and will not do any good. This is why when you are talking with people that have anything close to it, they does not show their cards.
