I trade multiple time-frames, one being 2-14 day swings. On swings, I've found RSI 5-day, $NYAD, $NYUD, and $NYMO useful. RSI-5 and $NYMO had a positive divergence from the $SPX over the past few weeks. $TRIN over 2 has been reliable for a rally in 2-3 days. I also integrate medium-term timing indicators to try to figure out whether the next 1-2 month move will be down or up. For this, I like a combination of Investors Intelligence Bull/Bear survey, RSI 14-day, 14 day stochastic, and the average five day range of the NYSE $TICK. If the medium term looks bullish, I'll overstay on my long swings and stay only breifly on short swings. Vice versa if medium-term looks bearish.
