Wants to Join a Tribe

Hello Mr. Seykota,

My name is [Name] and I am interested in more information on your trading tribe. How does one become a member?

Thank You,

Wants to Develop a System

Mr. Seykota, I am looking to develop a trend following system for currencies.

My background, I already have a profitable prop trading track record, and agree with the existence of trends.

Please let me know.

Thanks,

You might consider joining a Tribe, attending a Workshop and /or applying for private consulting.

On the Path

Hello Ed.

I bought your book from you some months ago. I have read it and have committed to reading it again.

I am a commodity trader for my profession and have a lot of outside issues and forces working in my personal life. I would like to read the book again and then figure out how to further my process, perhaps that means a workshop or something but I really have no idea how to begin that process or where to turn to or begin.

Can you assist me in a probable path I could anticipate going down and what may be a good fit for me.

Many thanks.
You might consider attending a Workshop.

Wants to Join a Tribe in India

Ed,

I wish to know if you have a TT in India.

If yes can you provide me some details. If not then can you provide with details of forming one.

Regards,
You might check the Tribe Directory.

Missing FAQ

Hi Ed,

I noticed FAQs have not being up dated for a while.

I'm a long time fan and was very engaged on reading FAQs but missing the updates since March this year.

Best Regards,
Thank you for your encouragement.

Bernoulli

Ed,

I found your web site during a search for the spool and card demonstration. Your radial flow explanation was helpful here.

I looked at the rest of your web site and noticed some comments about others claiming that Bernoulli can be used to explain lift on an air foil. There may be a few web sites making this claim, but actual programs such as XFOIL, use a simplified form of Navier Stokes equations to generate polars (the coefficient of lift and drag versus angle of attack and Reynolds number based on an airfoil shape). This is a complicated process that goes way beyond the simple equations of Bernoulli.

Despite some misleading web-sites about how lift is created, the experts that actually designing airfoils (such as the author of XFOIL, Mark Drela a professor at MIT), understand what's involved.

My interest in this is due to my hobby with radio control gliders. Some of the aerodynamic experts, like Mark Drela and Philip Kolb, design some of the high end contest model gliders, including creation of their own airfoils.

Thank you for the information.

Many textbooks still have it the other way around.

Looking for a Tribe

Hi,

I live in Pa. I emailed a gentleman in the Philly area but they are not meeting at this time. I would like to stay connected and learn LOTS more.

I've been trading for about 2 1/2 years and realize that trend trading is a most intelligent way of trading. I've developed an entry method using CCI and believe it will work nicely for my entries with the trend.

I have lots to learn and want to get at it. I'm moving forward in spite of not having a tribe to work with. I've read more than a few books like "Turtle Trading", Trend Trading, Trading in the Zone etc. I'm profitable using my system which I backtested one year in the currency markets.

I'm still working on discipline. Discipline will probably be the most important contributing factor to my long term success.

I'm looking forward to hearing from you and... if I don't - Merry Christmas and a Happy New Year!!

Best Regards,
You can attend a Workshop and / or start your own Tribe.

Bernoulli

Ed,

I'm a retired programmer, my last jobs involved embedded firmware in computer peripherals, which use simple pre-emptive multi-tasking operating systems (event driven). I specialized in RS ECC (Reed Solomon Error Correction Code), IDE / SATA interfaces, and wrote a few devices drivers (Windows NT and Zenix, a variation of Unix). Going back to the 1980's and before, I specialized in operating systems and device drivers for mini-computers.

As mentioned in my previous email, my interest in aerodynamics is due to my hobby with radio control gliders.

In my previous email, I left out Helmut Quabeck, another professor that designs rc gliders and airfoils (the HQ series). A short list of designers and their primary model glider names:

-Mark Drela - Supra
-Philip Kolb - Pike Perfect
-Helmut Quabeck - Icare / Icarus

There are others, but I don't recall their names at the moment.

This web site has a large list of airfoils: http://tracfoil.free.fr/airfoils/indexE.html

My interest in aerodynamics is due to my hobby, and also my curiosity about aircraft in general. Although I don't fly full scale aircraft, I know a few rc hobbyists that do fly full scale gliders.

Over the years, I've been trying to sort out the various web-sites on aerodynamics. Each seems to offer a different bit of the total picture.

Getting back to the point about Bernoulli principle and lift, it seems that Bernoulli principle as it applies to wings states the obvious fact that air accelerates from higher pressure zones towards lower pressure zones, and the equation shows a relationship between pressure and speed during the transition in a somewhat idealized model.

One issue that many of the web sites don't explain well or at all is how a wing adds energy to the air, resulting in downwash related to lift and some forward velocity of the air related to drag. It would be similar to the exit velocity as explained in the NASA article about propellers, except that for a wing, the pressure jump and exit velocity is smaller, and a wing doesn't operate in it's own induced flow like a propeller or helicopter when hovering.

http://www.grc.nasa.gov/WWW/K-12/airplane/propanl.html

I wonder about things like how closely induced drag times air speed (power consumed to produce lift) translates into power added to the air related to downwash.

Sorry for the short novel, I only meant to ask about the issue you have with Bernoulli and lift, versus my own small knowledge about the actual programs that produce polars for airfoils.

Thank you for the information.
