There's a bunch I look at depending on the situation, but my main goto is Elliott wave analysis. Once you know this, every other indicator/technique will become a secondary tool. You can learn the fundamentals outlined by Prechter, but Bill William's methods are a must to verify your work. What sort of TA do you do?
As for getting past losses, once you have a firm trading discipline with rules and limits (stops, margin management), you'll be able to avoid getting into the really bad spots.
Two main things that helped me: don't over trade and don't trade against the trend (unless you are good at spotting reversal patterns). And knowing the trend is just basic moving average analysis on several timeframes.
