Hi all, Do you know if there is a trading strategy based in the parrondo paradox? http://www.cut-the-knot.org/ctk/Parrondo.shtml Regards
It's vaguely similar to Shannon's Demon which is in wide use in professional money management today, hidden behind a suitably authoritative sounding name.
Maxwell had such a demon, as well. Why not cut the crap and keep drawing your account down to that integer multiple and playing winning game B2 all the time?
The article is misleading, particularly the reference to Maslov: "Dr. Sergei Maslov from Brookhaven National Lab had shown that if an investor simultaneously shared capital between two losing stock portfolios, capital would increase rather than decrease" Maslov showed no such thing, nor is what he did show (a version of Shannon's Demon) so complex that it cannot be applied to real trading.
This issue was addressed in the book "A Mathematician Plays The Stock Market" by John Allen Paulos. If I remember correctly, the conclusion was that no Parrondo-type trading strategy exists.
It sounds like all I have to do is trade any two securities any way I want and together they will show equity growth. That doesn't seem to happen to me though.
I guess they would have to be related in the way you played them or the way they behaved somehow. I was reading that article from the NYT and I got a funny feeling because the strategy that I am currently working out seems to be what they are describing to an extent. It is two games played on the same data, the market decides which one [or none] is played every bar, gains are locked in [ratcheted] during every bar.. it's a tremendously interesting subject that I feel [I can't say I really understand the theory very much so I use the word "feel"] could lead to some big up-jumps in typical gains for somebody...
Here you have two articles about this paradox applied to trading http://citeseer.ist.psu.edu/cache/p...CR.pdf/parrondo-strategies-for-artificial.pdf http://sais.se/mthprize/2002/almberg2002.pdf
