If you're trading based on RSI, MACD, Stochs... etc.... give up before you lose your shirt... don't let the part time paper traders fool you, markets are based on news and fundamentals.
Most should do so. If you're a Larry Connors fan - he uses RSI(2) as a cornerstone of much of his analysis, I'd suggest checking out Ric Miller who adds it to his sound statistical approach (and no, I'm not affiliated with Ric in any way - I studied Larry's work for a while, produced some great backtests, but Ric was the only guy I felt talked real-world sense). http://www.triplescreenmethod.com/
