Aleph - what you say is quite a common blief. And I've never known whether it's true or not actualy. From one hand - if a lot of people are buying (more buyers than seller) than price does go up. From the other - yes, still there has to be someone who sells...
WmWaster - you say there's a lot of traders etc. using automated systems. Well, I don't know any of them. I know some who are claimed to use them but that's all.
MACD? CCI? Man, these are the first I've tried. And the worse ones. Few spectacular gains and planty losses. Filter them? Yeah, that will kill many losers but some of winners as well unfortunately. Believe me - if I say I've tested them I mean it. And if I find or invent a new one which has any chanses of being profitable - I will test this one as well. But I know the result now without testing it
Long term trading? Yeah, I think it's the only thing left for me but I'm really bad in it. I will catch every movement in it's local peak - I will sell the high or buy at low and the price will go in my direction for few days but I will still eventualy loose, because I won't exit in time :/
