robert carver, who managed billions at hedge fund ahl, met a young quant who'd produced 50 profitable backtests in a month. the firm was liquidated a few months later.
the software could automatically test hundreds of rules a day. the boss was delighted.
carver's diplomatic reply:
“Well I am sure some of them will work.”
their joint venture discussions went nowhere.
this is classic overfitting from data mining. test enough rules on the same history and some will look profitable by chance.
from the book "systematic trading".

Nadie te lo cuenta, pero el mayor lujo de la vida adulta es trabajar con gente inteligente y competente.

Much of your adulthood will be spent dodging miserable people who think they're smarter than you because you're hopeful when they're not. They mistake your strength of spirit for naivete, and preach what has made them despair like it's wisdom. Everything is spiritual warfare.

Kita non-stop ngomong mulu soal tech transfer dan pasif berharap dari altruisme perusahaan multinasional untuk berbagi teknologi.
It’s not gonna work. Udah strateginya aktif aja.
Akuisisi perusahaan luar negeri dan IP mereka. Permudah beli mesin dari luar lalu reverse engineer.

I’m in love with this sentence:
“Every pattern in your life repeats until you learn the lesson. The moment you choose differently, the loop ends and growth begins.”

Read more books. Read to escape reality. Read to understand reality. Read to challenge what you believe. Read to think better. Read to write better. Read to argue better. Read to know yourself. Read to build something. A single book can completely rewire your brain.

The trailing stop is effectively a trend-following component, but that’s precisely the point of @basso_tom experiment.
It doesn’t prove that entry signals have no value. It simply shows that a profitable systematic strategy doesn’t necessarily require a sophisticated entry signal, expecially in presence of autocorrelated assets.
Basso conducted his experiment back in 1991. Could you share the title of the later Winton study you’re referring to?
