Quote from Quon:
Everyone has their own OR for their own reasons, the important thing is that once you get one that works for you, you stick to it. As a day trader weekly levels could help you to read intra-day price action around key weekly levels, but if you have something that works for you on an intra-day basis, why complicate things?
The more I re-read the book, the more I see the value of keeping things nice and simple.
