Baby 8ths

Just wanted to thank you for including the baby 8ths in the MM efs. Anyone who has taken the Murrey seminar and learned first hand how to trade the MM software knows the baby 8ths are the key to knowing price action movement. Keep up the excelent work

Matt:

Sorry for the delay in answering your question. The Pivot.EFS returns values to the chart (via the return() construct) and the chart object takes care of drawing the lines. In the HV scripts, I am actually drawing the lines using the linedraw functions (e.g., drawLineAbsolute and drawLineRelative) to create the histogram effect and it is these that do not (yet) work with tick data.

Value Area

Is there a way to change the Value Area calculation in the Volume Profile charts to 70% versus the current 68.2%

[ckryza]

Minitrader:

The value area is actually computed via a standard deviation calculation and 1 StdDev will give you approximately 68.5%. The best you can do is to use different multiples of the standard deviation in the value area calculation (e.g., 1.5 * std dev or 2.0 * std dev) to achieve the result you are looking for.

Look at lines 725 to 737 of the Historical VP script and you will see what I am talking about. You can make your changes right there. Same logic applies to the realtime script.

I uploaded new versions of the EFS help files (regular and HTML) to the File Share area (Specialty Scripts).

Version 1.8.0 of the PyraTool script has been uploaded to the File Share area. Added support for additional degree settings and reduced the number of buttons (now uses deg++ and deg-- to adjust degrees). Other minor cosmetic modifications as well.

New version of the Square of 9 script (V 1.3.0) has been uploaded to the File Share area. Added code so that the script will remember the settings for each symbol/interval combination you use it with during the day. Also added support for additional degree settings.

wavelet information

Greetings Chris,

I came across your wavelet scripts, and was impressed (keep up the good work). I read about what I could comprehend on the bearcave site you mentioned in your comments, but have yet to find a good description of a practical application using them.

Do you (or anyone) have any suggestions of how they should be used in market analysis? Like how they can be used for signals or confirmation of a signal...

Any input is appreciated.

Thanks,

Hi Joshua:

A typical use for Wavelets would be in time series analysis (along with Fourier transforms and MESA). They can be used to break down a time series into it's frequency components and they can also be used to filter out certain frequencies in the time series (e.g., remove the noise from the data). The wavelet algorithms, on average, tend to be faster and more efficient (in terms of CPU usage) than Fourier, Lomb and/or MESA algorithms which makes them popular for real-time applications. (However, the Lomb and MESA algorithms are more robust (in my opinion) for cycle analysis work.)

A direct application of Wavelets would be to use them to create a filtered signal as mentioned above. The filtered signal could be used in the same fashion as a Kalman filter or an adaptive moving average. The idea being that the filtered signal would be less sensitive to minor fluctuations in the data and, therefore, less prone to whipsaw. Another application would be in the area of neural networks.... which often use wavelets as a mechansim for pre-processing the raw time series data.

New version of Vol Profile Realtime (V 1.7.0) uploaded to File Share area. Added VWAP calculation as well as a minor fix so that script starts calculating right after the open.

Chris -
I'm new here, but just wanted to thank you for the work it took on these. I've been "tweaking" (just cosmetics) the VolProfileRT and the PyraTool and am thoroughly impressed with the documentation in the code.
Quality stuff... thanks.

I'll second Marks commment.

Chris your stuff is terrific.
Volprofile is tremendously helpful for my trading.

Thanks

Matt & Mark:

Thanks! I'm glad that the scripts are working out for you.
