There is no perfect trading system.
I have developed, coded, and tested literally thousands of trading systems. I am not exaggerating. They are all imperfect. Now, I would have always agreed with that on a intellectual level. But I think I did not really “get” that until I had done the work of developing these systems and tested them though various market conditions.
Now I think of systems in terms of yield. A system is not unlike a bond that has a yield that streams off of the instrument itself.
If you like things more literal. Imagine you build windmills. You can maximize efficiency of your blade shape for different speeds and frequency of winds. But one blade will not be efficient in all conditions. Just like a real wind farm, you maximize your blade shape for your prevailing wind condition. If the winds are significantly above or below that condition it is often best to just brake-stop the windmill.
System designers obsess over the shape of their blade, but they often do not think about measuring the conditions in which that blade has maximum efficiency.
This is one step along a long road of merging with machines…

All power to the proton: Researchers make battery breakthrough

So the fact that the program – or any such program – does as well as it does here means, folks, that the handwriting is on the wall. Not this afternoon, and not next week, but in the easily foreseeable future retrosynthesis and synthetic organic chemistry planning are going to be taken out of the hands of chemists. At least, that’s how it’s going to seem to us, the chemists of the present. But to future chemists, the ones who will enter the science once this transformation is complete, it won’t seem like that at all. To them, synthesis planning will always have been something that you have machine help with – why would you do it any other way? Who can carry a zillion reaction examples around in their head?
Behold the rise of the machines. It’s been going on for a while, but there are landmarks along the way, and we may have just passed another one with the publication of this paper. It’s open-access, from an interestingly mixed team: the Polish Academy of Science, Northwestern University, the University of Warsaw, the
