How do I get to the screen in the top link?

hi you get your steam window
first step: click on your avatar (picture of your profile to get to your profile page.
second step: click inventory
third step: at the right corner of the window there would be a link to trade history click that
step four: if you are going to make a screenshot block your log in name since it's a step closer to being hijacked
