Quote from saxon22:
After trying countless indicators and more methods than I care to remember, I was thinking, how do the big guys trade? I doubt, they use all those fancy tools we have at our disposal. However, if they do use them, then which ones and how? Any ideas?
You might try contacting some of your favorite big guys and ask if you can visit them and talk trading. It works for me.
If you meet a big guy, please tell us everything.
Some clues exist: I recall reading that Global Alpha, Raptor and Renaissance all experienced equity draw downs about August 2007. I interpret the shared draw down to mean these funds use methods that share some common element(s).
A speech by Jim Simons of Renaissance Technologies is published here: http://www.elitetrader.com/vb/showthread.php?threadid=96757
These are some quotes from the Jim Simons speech that I find interesting:
"We decided that systematic trading was best. Fundamental trading gave me ulcers."
"I decided to just focus on making models."
"We understood the limitations of very high-speed trading techniques. We looked at other factors besides intraday fluctuations," he said.
"From high-frequency trading, Mr. Simons evolved to a system that focused on the long end of the frequency spectrum."
"The computer does its thing. It generates its trade, and the trade gets executed."
So Mr. Simons trades systematically, buy sell signals are generated by a computer program, and trading is long term.
