I always have a question about this mechanical system trading vs discretionary trading. Aka, the HFT nowadays. I don't have too much knowledge about how they do trading. But I know that they are all rely on the techinals. They(quants) build the trading systems by using FIB. Stochastics. Pivot point , etc. all the indicators. They can watch all the markets and watch the correlations of them. Lots of hedge fund companie generate huge %of returns per year. Does that mean that discretionary trading will not work one day?

Grasshopper... the one who had read Sun Tsu's Art Of War at 5 (was that right?)...
Sun Tsu said: Know your enemy, and know yourself. Your enemy is 10 times bigger than you... does not mean you have no chance of winning. You think that with all the resources that USA has, winning at Vietnam should be easy, right? (Or the Soviet over Afghanistan (or now the USA over Afghanistan)) There are always strategies that may work for the small guys.
Mechanical trading systems... I don't think it's all that simple... trading with Fib, pivots or what not. They may not need any of that. Imagine if your machines can be co-located with the exchange's servers to reduce latency, and that you pay someone the privilege of peeking at customers' buy/sell orders for a fraction of a second before the rest of the world has a chance to, and the virtually unlimited capital to take advantage of any opportunity no matter how small the profit on each, and the supercomputer which can do it all day long on thousands and thousands of equities that can be exploited, repeated for thousands of times over...
