Actually, it has Ergodic and TSI with the correct formula from Blau's works.

Perhaps you meant it doesn't have any custom ProfLogic Ergodic yet?

Yes, it isn't my parameters for the ERG.
 
Quote from 1a2b3cppp:

Here is an ESZ8 chart with 16807 volume bars (ProfLogic's number) with the default Erg, Erg signal line, and Erg Oscillator (histogram).

That's pretty good except I use a single line to elininate distrations and the crossovers are the oscillations. Add the Primes and you will a good start.
 
Quote from 1a2b3cppp:

ProfLogic, looking at your attachments, what is the difference between the big arrows and the little arrows?

What is the reason you take *some* trades when the histogram is above the top horizontal line and then reverses slope and turns down, but not others when the histogram is above the top horizontal line and then reverses?

Is that two Ergodics you have plotted there? The histogram is a faster one and the red/blue line is a slower one?

Large arrows are user (me) placed to show trade placement areas. Not specific bar entry but simply the fine tuned area where the trade was executed.

The small arrows are computer generated and show the specific bar where the Trading Oscillation label first appeared. The Trading Oscillation label come from the next fastest (larger) fractal chart. The Trading Oscillation is where the decision making process begins to set in motion the execution process. Everything I do is objective base and a step-by-step process; if this, then this.

The Histogram Oscillation (denoted by a color change) is simply another step in the process of executing a trade. The histogram oscillating at a Prime level simple shows that price is oscillating at a high level of strength. Any other oscillation shows price creating a top or bottom that isn't as strong. Histogram is generated from next fastest (larger) fractal chart ERG oscillations.

Each step separately means little but each step in sequence is critical.

1a2b3cppp, ProfLogic,

Just trying to follow along here.... using Tradestation, I'm trying to create the same chart / ergodic as you have posted.

I notice there are some differences between what you have posted and what I am able to get. I've obviously tried to tweak the settings but that doesn't quite cut it.

Would be great if you could take a look and let me know any quick thoughts on following:

a) Any ideas on what may be causing the differences? (The hand drawn arrows on the chart hilight where some of the differences are)
b) Are those differences really meaningful for the methodology?

From the posts it sounds like there are differences between the standard version of the standard version and the version of the ergodic indicator you are using. Could that be it?


I also had some additional questions on the methodology but figured I'd started by first trying to replicate the chart setup as closely as possible.

Thanks!

I'll see what I can do to find it.

There are 2 old threads here on ET where ProfLogic explained everything in detail... plus some.

Hopefully we can keep this thread on point and eliminate the . . . plus some.

It seems that a lot of people are trying to get the indicator, but there is little discussion as to what it actually is, or why it provides useful information.

I see a two things in ProfLogic's method that I definitely agree with.

1) Removing time and using constant volume bars. Price moves relative to information -- and an excellent proxy for information diffusion is volume. His values seem rather arbitrary -- but if they work, they work!

At this point, I would ask why the values are not self adjusting to volatility -- but I suppose that really only matters at a more macro level, or over a longer time period. For example, values that might have been 'slow' in 1995 might be 'fast' now, due to an increase in total volume.

2) "Fractal" space. By looking at the slower fractal above, you can get a good idea as to direction (and perhaps strength?) of the primary trend. Since your trade should be contained within your fractal (for example, a trade taken on the basis of 5 minute bars should not last months), the only primary trend you have to be aware of is that in the fractal above. I like this a lot.


The rest gets a bit washy for me ... but only because I don't think I understand it. Evaluating Ergodic, it seems to be a derivative of TSI, which looks to be, at first glance, a momentum indicator.

This would indicate to me that ProfLogic's Ergodic is basically a trend/momentum system? By using constant volume bars, we only take into account 'significant' price movements, reducing noise. We then look at two trends, our current fractal and the slower fractal, waiting for a confluence. Then, we use the confirmation of momentum to ensure that our trade is going in the right direction. At the wane of momentum, we begin looking for our exit.

Is that correct? Did I mess something up? It seems like a logical system to me: reduce noise and wait for a confluence of signals that identify a profitable opportunity.

1. The values are based on Prime Numbers. One is obviously unuseable, 3 offers too many chart choices, 5 ends up being too noisy being that each increment is divisible by 5, 7 was perfect for number of choices and finally 11 was to large so I went back to 7.

2. Exactly correct!! Every trade is taken inside your defined Trend so you always know where your price direction and strength lies.

The ERG is a momentum indicator simply mirrored to price movement. Other than that you nailed it. Logic works in the correct environment.

Well done.
