There's discretionary traders and there's automation (codes/program) traders.
The automaton (codes/program) traders obviously believe trading is scientific. In contrast, discretionary traders uses a little of everything but no automation. Thus, on any given trading day for a discretionary trader, good or bad, there's usually a reason behind that particular trading day results. For example, one trading day the key to profits or losses could be discipline. Another trading day the key could be the trade signal. Another trading day the key could be trade experience. Another trading day the key could be risk management. Another trading day the key could be diversification, another trading day the key was one lucky trade, another trading day the key was collaboration with one of your trading buddies and so on...
That's discretionary trading and I don't have any problems with it being called an ART. I've read in various science magazines, psychology magazines that the human mind can do things that computers can not do. Yet, that gap between the two is closing.Therefore, its not that it appears grey...its more like a discretionary trader has more things to deal with or manage...something most traders fail at involving
managing their trading plan that involves all the above mentioned.
By the way, I always get confused by another group of traders that call themselves mechanical traders. Usually someone using an indicator system but they manually enter/exit their trades. Thus, I'm not sure if they are really just discretionary traders.
Yeah, discretionary trading is highly debatable. Most of the TA debates by the naysayers is with discretionary traders. The TA naysayers are
not too smart to understand they should be debating with the automation traders that believe TA is scientific and can be quantifiable proven. They're the ones they should be pointing their fingers at when they demand seeing
quantifiable proof.
I find the above mix up by the TA naysayers hilarious as they continue asking discretionary traders for codes or quantifiable proof.
I also find it odd they don't bother the program system designers using TA down in their threads...very strange as if they're too afraid to debate with those about the scientific aspects of trading.
