Quote from jack hershey:
Willmott does it's narrow thing. Wikkipedia does the broadbased thing. Why not parallel these kinds of things with a least one baseline substantive teamwork effort on making money by trading?
I'm sure there are many reasons to not do this. Are there a few reasons to do it?
Jack,
On your comment about a teamwork effort, I've attached part of some discussion on another forum. In it we have some survey results on profitability in trading systems. In summary, there are few who will admit to making much profit. There is of course much talk about how to do it, but few will admit to having done it.
The second par of the post I quote below proposes something call a Blind Binary Collaborative along with my experiences in various private investing teams and why they don't work.
The response to the idea of a Blind Binary Collaborative was nil. The talkers have nothing to contribute and those making significant returns from advanced systems have no need to collaborate. This leaves very few people to build a team with.
However, I'm still open to the idea for anyone using predictive models with the technical skill to handle automated exchange of predictions.

Even in general trading groups the results are similar. Here is one from Profitable Trading:

Your comments have sparked an idea, follow me on this if you will in my next post which will outline this in a new thread.

Blind Binary Collaborative
Your idea as a general concept: People cooperate on creating trading systems with improved profitability
Comments: I've been in a few of these over the last 5 years. These ranged informal Internet cooperation like "here's may data and results, can you improve it?" to formal undertakings with proposed contracts, percentage splits of profits, web sites and hundreds of hours of group live chart with multiple parties world wide. In the end all came to naught for some fairly simple psycho-social dynamics.
People who have only an Internet relationship have a very low level of bonding. One can spend lots of time on emails and analysis one week but when you see a better use of your time or have learned all you can from the interaction with the others in the group the motivation for additional cooperation quickly vanishes.
Additionally many people in such situations present themselves with all kinds of skills and resources to gain admittance on the hope they can learn a lot before it's obvious that they can't carry their weight. Then those with skills conclude that they have a better use for their time than giving others a free education... and pop, the group vanishes in smoke.
Since this kind of work is a bit like prospecting for gold on the surface there is little self interest in telling others the best place to look for riches.
Summary of Dynamics:
1) Human nature dynamic: Greed and self interest = get as much as possible while giving as little as possible.
2) Human ego: What I've discovered is potentially really great, if I could just refine it a bit, why should I share my best stuff until I know I'm getting something back of equal or greater value. So I'll toss out a few tid bits and see what I get back.
3) Fishing Expeditions: Folks will announce they have this great system, a string of investors and anyone who can help a bit with a couple of loose ends will soon be rich if they join forces. We have had some of these on this group. They usually vanish after one post.
I could go on but if you are still with me on this, you might agree that these issues present a real obstacle to real cooperation.
New Idea: A Blind Binary Collaborative
What does such an odd string of words mean?
BINARY
A binary in many areas is something that takes two things that are kept separate in order to work. Some kinds of Epoxy adhesive require the mixing of two compounds in equal proportion to make the glue. Another example: the triggering sequence on nuclear weapons requires that two separate keys be pressed at the same time by two different people.
BLIND
Nobody know who or what is involved in the process. A blind taste test for a consumer product. If people knew what they were tasting the results might be skewed. A numbered Swiss bank account is blind in there is only a number and a password, the bank is blind to who you are in normal operations.
COLLABORATIVE: Some kind of cooperation.
How would a BBC work?
The key thing is that it would
1) Eliminate the problems I cited above
AND
2) Require ongoing contribution from all parties.
Let me give and example of how it world work and let me know what you think.
Assume you and I decide to BBC on the Russell Index Future.
We both start with the same data.
We both attempt to forecast the variance in average price 5 bars into the future.
You do whatever you do to model that, say you use 27 carefully researched Dependant Variables and a combination genetically mutated NN architecture of your own design to forecast the Independent variable.
You send me the result.
I do whatever I do on the same original data set. Perhaps I use 6 different architectures BPM, SOM, RBM and a couple of GA modules on my secret 14 variables. I send you the results.
Neither one of us share anything about our methods, architectures, designs or discoveries....ONLY the result.
We each then combine the results of or best efforts by whatever means makes the most sense to us, to generate trade signals. We share the trade singals.
Assuming the results are something better than what either of us could do on our own on the Russell we will likely both trade the Collaborative results. Since neither of us will know anything about how the other person did their half of the system, we are both strongly motivated to:
1) put forth our best efforts and
2) continue to cooperate and generate signals. If either person stops, the system stops working because it's both Blind and Binary. In that case we are both left with what we started with.
This idea, while radical, eliminates the obstacles to cooperation, all that effort spent on cross education and trust building and focuses on hard results: is the Collaborative results better than what I had on my own?
