interesting. looks like everyone is pretty much the same, most start work only when things don't look good. but I have never had a system that fail on me. I think I am just lucky, but my systems are quite stable, I have system that have give me 3 yrs of good performance. I would say that Most of the time, it's not the system, but the market that is influencing your results. if volailtity dries up and the market goes into a complete standstill, even holy grail will not make you any money, (not including market-making systems). my next question is do u come up a idea first b4 writing code or do u just sit in front of the computer and just work on the data?
Never................but..... sometimes I don't trade it and every so often I lose discipline and trade against it. That usually results in a lesson on why I should stick with my system.
depends on what your system is, and how stable it is. LESS STABLE - one market, one strategy - one market, multiple strategies - multiple markets, one strategy - multiple markets, multiple strategies MORE STABLE you get the picture...anyways, the less stable your system is, the more watching and tweaking you probably need to do. for me, i have used my programming skills to automate many different strategies/markets. in a way, THAT is an edge unto itself. it is a hedge against ignorance. i'm usually a bit late in noticing when certain edges have fizzled out (i'm a bit lazy sometimes), but i KNOW that i'm lazy, and therefore i have programmed that into my system.
when it stops working for christ sake.. what kind of question is this?? i aint changing nothing 3 months 3 years or 30 years till i start taking enuf hits that i wake up one day say hey smthg is wrong i think ... ?????????????????????? Q's like these tend to baffle me..
