Very cool Jeff. We're always finding out about new tools through your code snippets over these years.

Ehlers Super Passband with Floating Levels

This is Ehlers super passband indicator with floating levels. Floating levels choices are the standard rms envelopes, regular floating levels, or quantile bands. Color choices are middle line cross, outer levels cross, or slope change.

As described by John Ehlers

This pass-band oscillator seeks to pass-band out both high and low frequencies from market data to eliminate wiggles from the resultant signal thus significantly reducing lag. This pass-band indicator achieves this by using 2 differenced EMA's of varying periods. (40 and 60). Trigger points for the pass-band oscillator are added with a RMS cyclic envelope over the Signal line. Output of the pass-band waveform is calculated by summing its square over the last 50 bars and taking the square root of the averaged sum to create trigger levels.

Thank you mrtools, any chance of audio alerts + arrows, please?

Ehlers Super Passband with Floating Levels + Alerts & Arrows

Hello, added the alerts and arrows.

Description of this code can be found, here: Ehlers Super Passband.

Years ago, I corresponded with John Ehlers and asked
him about his indicators. The result was, among
other things, the attached experimental indicator.
These are bands built on Ehlers's instantaneous trendline.
Two bands are linear, a la Keltner, and two are nonlinear,
a la Bollinger. Looking at it, the only advantage
of this indicator is probably its stability in the sense
that it doesn't recalculate / repaint.

As a side note: Ehlers codes his indicators in EasyLanguage
and often uses trigonometric functions. The measure of an angle
in EasyLanguage is degrees, while in MQ4, it's radians.
So, for example, 180 degrees in EasyLanguage must
be translated into Pi in MQ4.

The indicator is highly experimental, so for now, I have
decided that access will be limited until the end of August.

You actually spoke with John Ehlers dude?!

Only by email. He was very polite and answered all my questions.
I was fascinated by his indicators at that time.

and now you're producing all this crap. maybe you should've asked his more questions....haha just kidding
i'm messing with you

What I need is the indicators in this video :


i'm talking about these ones

I coded a dozen of his indicators, and this one
was probably the best - the instantaneous trendline.
The idea to add the Keltner and Bollinger bands to it was mine.
This indicator is very old, but I think it's somehow interesting.
The market usually moves at least from one Bollinger band
to the next and back again, but of course not always - it would be
too easy.

But I'm also skeptical.
