I was at your survey - you should not think only about trading systems to buy. there are online ones just to use (well, maybe a small fee to pay).
well if u ask me i don't beleive in investment systems... i beleive in investment strategies... both are very different systems are predefined meaning that when this specific technical combinations occur give buying signal or selling signal. its without human intervention. on the other hand strategies is way more complex... strategies u have to take in account the human phycology, economics internal and external. the technical aspect that may help u factor out poor performance ect... this are just small of many huge factors... but its to only give u an idea. chahine
