You are right in that ArchAngel, it is all in what works for you.
There are so many theories of how to trade, it is all in the practical application of it. And depends on what you are vehicle you are trading.
For what I do, indexes, plotting support and resistance is key. Often it is in just notes I make on my charts. Like ES has had a hesitation at 980 for a while now. That is not exactly a pivot, it is just what we see everyday.
Just a note on pivots, fibonacci, and Gann.....they are all approximate reference points, not exact ones. You need to remember that and not base your trading decision solely on the one indicator.
