chi - take some time and go thru these forums. I am not saying that indicator(s) are bad, but they are not a solve all. Expect them to fail. It's not going to hurt to learn 2-3 and then learn them inside and out. Popular ones appears to be Stochastics, MACD, RSI... among many others.
Some guys have 20 indicators on their screen and analyze that way. Personally that is way too much for me and would rather know a couple things inside and out vs. kind of knowing 20.
And you have traders that simply analyze price and the current action, tape readers, etc. Those guys are around here too.
If you want to use this forum properly, you are going to have to spend many hours reading the posts that are already here. Most of your questions have been asked, you just need to find them. It's overwhelming at first, but now that I have been here a little while myself, it never fails to see the 'I am new help!' threads that just ignored b/c we see them weekly.
