Advanced RSI — Mark 4

RSI was introduced by J. Welles Wilder Jr. in 1978 in New Concepts in Technical Trading Systems. It measures the velocity of gains vs. losses on a bounded 0–100 scale and popularized the 14-period lookback with 70/30 guide rails for overbought/oversold. Over time, traders added variations (different lengths, thresholds, smoothing, adaptive levels), but the core idea stayed the same: momentum turns often precede price turns.

and i initially started to make minor adjustments for personal use like changing the default to 17 , and using Tradingviews official RSI which comes with a MA embedded. but it was not enough. especially the visuals.

so, for this public release Mark 4 i enhanced RSI by incorporating :

1. Dual-Length Fusion
Two RSI periods (default 17 + 21) blended then lightly smoothed (TEMA by default) → steadier
line without dulling turns.

2. Adaptive OB/OS (ATR-aware) for fewer whipsaws.

3. OB/OS alt solution:
Brief yellow segments appear only at local extremes (default: >72 tops, <32 bottoms) to
emphasize exhaustion without repainting the whole line.

4. Signals you can actually see
Triangle markers for:
Bullish: RSI crossing up through adaptive OS (and still <40 at the cross).
Bearish: RSI crossing down through adaptive OB (and still >60 at the cross).
“Strong Bull/Bear” background nudges appear when momentum is pushing beyond the
bands.
Optional Divergence Tags
and
Tiny diamonds to flag potential bullish/bearish divergences (look-back based).

Info Table (can be hidden)

my Fav feature i included 5 colorways with modern themes.(pls check under INPUTS)
and i made all that to make the indicator visualization look awesome on high end displays.

Credits & acknowledgment
Inspired by the original RSI by J. Welles Wilder Jr. (1978).

Built to be modern, focused, and comfortable for long sessions—especially on dark/OLED displays.

THIS INDICATOR IS MORE THAN ENOUGH BUT I DO HAVE PRIVATE INDICATORS WITH DIFFERENT LOGIC FUNCTIONS.

I'm open for feedback/collaboration.
