I was referring to the definition of a system, which is set up to override things like discretion. Choosing to do something is also referred to as discretion.
Therefore if you are not a discretionary trader, then you follow your system no matter what, or else you are not trading a system. At this point you are what they call being discretionary.
In trading, you can pretty much do whatever you want to do, which is why most fail. Therefore you can take a week off if you CHOOSE to. And if you are making enough money, you probably wouldn't notice the difference...but are you supposed to? No. You are not supposed to as it defies the logic of your non-discretionary system which is based on statistics to do so.
If I make $100,000 a year trading, a bank will loan me the money to purchase a $70,000 car. Is this the most intelligent thing possible? No. of course not. Can I do it without really suffering major repercussions? Yes, more than likely.
Like Brownsfan said- it is about consistency, and yes you are supposed to take every setup your system provides if you are a system trader. Otherwise you are toying with the statistical edge your system is supposed to provide in the first place.
