The concepts, in the real world.
Theory is easy to nod along to and hard to apply.
These cases highlight the moments the market tested it for real: the booms, the busts, the frauds, and the famous trades, each one taken apart with primary sources and a clear view of what happened and why it mattered.
Every study shows the IWP Concepts at work and links to every idea it touches, so you watch the same principles you are learning play out with real money on the line.
