Enough to abandon all off-chart indicators. I just use 20, 50 and 200EMAs now. It's going well. For me, long-term trend-following is the only rational approach and off-chart indicators don't add anything significant.
I meant to comment on this days ago, but got distracted.
But I didn't realize that my own approach,
basically, to consideration of longer-term market action -- like yours, tomorton -- doesn't really involve "indicators" at all, besides perhaps a 20/50/200 [SMA] cut. I forget that as an instinctive tick-scalper (with a whole protocol of 1 each: trend, volatility, oscillator indicators for short-term), I look at longer-term stuff with price and volume alone. (*Nearly* alone?? I still "respect" the ADX/DMIs on longer-term stuff, but probably more as a curiosity than anything else. Huh!

)
Yeah: I just checked my SPX chart, which I use with 1day or 1week candles, out between 3 months to 5+ years. I have trend lines drawn on it. I have a 2% envelope following price. These have been helpful.
OFF-chart, I have
a Lane's Stochastic (useless in an uptrend),
a Chaiken Volatility measure (algebraically, a slight re-do of ATR), I put it on a month or so back, to watch it and see what it does. A mild question.
an ATR (a check on HV and IV as charted nearby)
the HV and IV (for gauging the options market)
and the aforementioned ADX/DMIs which -- having just checked -- provide a pretty good set of entry/exit inputs, should I have wished. (Undoubtedly, they informed a lot of top-side/bottom-side bias in positioning option spreads -- just not something of which I took explicit note.)
So, on my "whole" SPX chart, I have 5 indicators: 3 as measures of option-selling attractiveness (nearly unrelated to SPX pricing), 1 price oscillator (useless), and 1actually used+useful (the ADX/DMIs).
THE WHY of this is something that we could debate for a while, I think. For myself, my "Overall Market Thesis" says, "If it lasts more than 36 hours, it's driven by fundamentals and will not be measurable/informed by an indicator." whereas non-noise movements of shorter duration (1min to 1-hour) might be *sparked* by fundamentals, but will be hard to hide from technical discernment.

!! [And in-between, since I'm jotting down random points, comes the TRIN, to bridge the 1-hour and the 1-day range. Hard to hide big selling/buying agendas from TRIN impact. "Yay!"]


AND SO, BACK TO THE ORIGINAL POST........
What's my *favorite* indicator??
"It depends."
Short term (1min candles, maybe 1hour).... Lane's Stochastic, informed by the nearly-redundant Money Flow Index. (divergences get my attention -- the MFI is volume-weighted.)
Long-term (1day to 1week candles)... 20/50/200 SMAs, informed by the ADX/DMIs (which, if you're *really* up on your skill set, are candles reworked to a linear form).
