Quote from newbunch:
It's quite funny that you ask that. I read all the time on these boards or in Market Wizards or all those trading psychology books (Trading in the Zone) about how hard it is to stick with a system. I have absolutely no trouble doing this. In fact, my system is at the low end of it's performance range over the last year or so and I still have no problem sticking with it. My biggest problem is being patient. In fact, I don't worry about drawdowns, I worry more about the amount of time to make money. I have no trouble suffering a drawdown since I'll make the money back soon. But doing nothing (which happened with the low volatility we have up until very recently) is tough.
I think one major reason I can stick with my system even when/if I don't know what it's doing is because I built my system from scratch. I built in in Excel over a period of years. It's not like I got some quant program, plugged in some variables, optimized it, and now I'm trading it. I first had to come up with theories about how the markets work, test them, develop them, test them again (backtested using about 50 years of end-of-week data), trade them, monitor the performance, automate the trading, then monitor the executions and performance. When you do all that, you are much more comfortable with what your system says than what you say.
Besides, if the Fed Chairman says something and the markets move and I'm manually trading, I have a few seconds to react. Can those few seconds of thought really compete with the years I've put into developing my systems?
In the end, I guess I just have more confidence in my market theory-systems development-backtesting skills than I do in trading skills.
