You make a fair point, im not suggesting they arent important - they may even lead prices but for us mere mortals how can we use them in a mechanical way?
I mentioned the COT because that records the positioning of all the main players - who will have a fundamental view on all the things youve said.
Why try to make it harder by redoing the work yourself?
Im just not clever enough to understand the whole interest rate economics thing anyway.
But Ive heard the Big Mac index is as good predictor of prices in the long term as any other.
I guess im just blessed not to have to worry about every little factor in my trading.
