There is nograil, for it already exists. I will repeat my IMHO in this thread:
Если считать граалем гипотетическую 100% эффективную торговую систему, то в конце концов она должна поглотить весь рынок, и заместить его собой.
То есть рынок и есть грааль . Так что грааль есть, и в то же время его нет.
И весь этот спор вырождается к курице с яйцом... :)
And the drawdowns will increase from 20% to... 200.
There is no grail, all believers are dead!

Thank you, Sergey, at least you noticed. That's exactly what I wanted: it's been two years in the Inquisition, it's about time to match my appearance...
P.S. And I did not notice a bit of inquisitorial in your look.

I always thought that only cologne was TRUE, but here you say that ASH CERTAIN GRAAL is also possible??? :-)
If a hypothetical 100% efficient trading system is considered a grail, it should eventually swallow the entire market, and replace it with itself.
This is the proof of the non-existence of the grail I hear all the time. Can't you do it without absorbing all the money? Are you familiar with the concept of "enough"?

I am familiar with it, the grail is not, otherwise it immediately ceases to be the grail...
Even if a grail actually exists, it is not certain that it can be found in any reasonable amount of time.
Here is an example for an analogy. Chess is known to be a game with complete information (i.e. with a deterministic move tree). It has been proven that for such games there is always a way to calculate and construct a strategy that leads to a win or a draw. However, this does not mean that anyone will ever find such a strategy - there are too many options.
What to say about the market, where complete information is probably not available.

And also think of the game "Go" - it is also a game with complete information, but so far only one programme has been able to beat the champion, and the others are an order of magnitude weaker, as I read.
