Here's a link to a 200page PDF with everything you'll need to know about - price volume spread and close
if you turn to page 77 and look towards the bottom it describes what that bar NO2. on today's chart was all about
this is a large and old book but still a very very good one to learn the basics from and also I'm not here to recommend the product even though I use it, basically cause they don't sell it no more they only lease it
