Take it easy.
You don't need to read a book about divergences. If you want to learn about the concept, go through the appropriate grade in the BP school:
Divergence Trading | Trading Divergences | Learn Forex Trading
Then watch the ICT video "How Professionals Use Indicators".
That will do much more good than reading a book about this topic, trust me.
By the way, I googled for SMT using also synonyms, but could not find a single website/forum talk about it. It seems it is unique here on BabyPips.
