At least not very much.... There is a price action journal which is great, I love it. But it seems strange to me that no one tries to read supply and demand. Price action is not the end all, supply and demand is. Price action is, yes, derivative of supply and demand. I understand of course price action and indicators and everything else have their place and there are a million ways to skin a cat..it just seems a little peculiar to me that no one ever mentions or talks about trying to interpret supply and demand in trading.
