What Are Stretch Targets?

One of the things i've heard you speaking about in the past is a thing called stretch targets. Ad i'd like to hear a little bit more about it. I mean, what are stretch targets in and how were they used amongst the trader you've worked with? If you cold imagine three zones a the first one would be comfort zone - that's the zone in which you know what you're doing. And then the next zone would be your stretch zone -- an area where you're having to switch on in order to sort of successfully operate or orto formin that thatintat in that area. Beyond beyond the stretch zone,you've got your panic zone...your fear zone.
