I'm mainly interested in gold but the question if valid for other metals as well. I'm curious what data people are using for their charts. Using gold as an example, if I use only the US NYMEX hours then this wouldn't take into account the european hours. Since gold is traded globally, I think it makes sense to use 24 hr data. But I'd like to hear your opinion.
I can go into a multi week time frame if needed more important than the time frame however is the action taking place outside of gold
