Has anyone ever experimented a Turing Machine based trading system?

Most, if not all, trading algorithms nowadays are based on Turing Machine, I'm afraid.

Thank you Freddie, for me it's not bad news. I've experimented TMs by myself using Excel, having very interesting results.

I agree that almost all algorithmic trading systems are Turing systems, if not in original design, then in their structural form. I would be wary of the system shown in the figure above. In my books, I have a system that has an equity curve like the one shown, and it crashed in the out-of-sample period ("The Strategic Analysis of Markets Method, Volume 2: Trading System Analytics," Chapter 16. The problem is that the out-of -sample curve keeps going up, but the volatility is quite different. You've probably overfit the model.

Turing machines are only useful in demostrations of computability they have no practical use. Too slow. The vast majority of computers are Turing complete however https://en.wikipedia.org/wiki/Turing_completeness

Waldo, of course. It all depends upon what type of information you need to compute. For computing numbers or equations you are right. I experimented Turing machines for computing patterns, and the result is interesting. With a TM you can give a pattern as imput and obtain another pattern as output. No need to transform or normalize the pattern.

I think what you heard about Turing Machines and Trading is Neural Turing Machines actually. Since that makes more sense: https://en.wikipedia.org/wiki/Neural_Turing_machine wich turned out to develop into https://en.wikipedia.org/wiki/Differentiable_neural_computer I was reading a couple of days an article about it. I published it in my forum some time ago.

If what you want is to transform one pattern into another pattern there are better options depending on what you want to do. But I advice you something. Don't expect a price in a market to be the result of another price. The only known pattern are elliot waves and those patterns are based on mass psicology that is dying slowly as psicology moves away fromthe market and computers start to take over.
