Okay, did some looking. Found this:

So it is directly related to ICT. Here’s the quote:
Smart Money Concepts originated with The Inner Circle Trader (ICT), which is a program offered by a trader named Michael J. Huddleston. ICT offers some free resources as well as paid Forex mentorship.
SMC sounds highly technical when you first start reading about it. You may find yourself scratching your head at the basic vocabulary. To help you out, here are explanations of some common terms used by SMC traders:
- Order blocks: This terminology is used to discuss supply and demand. Some SMC traders say that order blocks are a more "refined’ concept than regular supply and demand, but others contest this claim.
- Breaker blocks and mitigation blocks: These terms refer to support and resistance.
- Fair value gaps: This term refers to an imbalance. There are a variety of different types of gaps, and they were all identified years ago. Some examples are common gaps, exhaustion gaps, breakaway gaps, and runaway gaps.
Plenty of pros and cons listed. Seems more that people are mad that he teaches something that was taught in the past, maybe using a different name.
