You guys talking about using TA in short time frames are nuts! If TA is predicting a move in the short run (like minute, by minute), then it's doing so based on the existing market volume. Then a big trade comes across where someone wants to buy or sell a large volume in a hurry, and conditions just changed. IMHO, you need to trade in a time frame long enough that large orders aren't going to swamp your row boat. Yes, you can trade in the short term, but you're taking a big risk for not much more return than swing trading which doesn't have the kind or risk.
