I would add that it is always worth checking the weekly chart as well as daily/intraday. For example the daily for CDX shows a change of character (volume) with decent price appreciation, which looks good. The weekly shows a doji (indecision) on declining volumes and looks a little extended (far from MAs).




Also, longer term trend lines are often more significant than short term ones when determining support and resistance. Some are easy to spot, others less so.



Other than that, find what works for you and eliminate what doesn't. Be creative - no one has figured out the perfect system yet!
