The ICT and SMC vocabulary: market structure, liquidity, order blocks, FVG and manipulation.
ICT trading, short for Inner Circle Trader, and Smart Money Concepts describe the same family of methods: reading a chart as the trace left by orders too large to fill at once. SMC trading is the version taught outside the original vocabulary, with the same ideas under different names.
It is neither a strategy nor an indicator. It is a reading grid, and it is learned in a specific order: market structure first, because everything else attaches to it, then liquidity, which explains why price goes hunting in certain places, and only then the entry zones, order block, fair value gap and inverse fair value gap.
The lessons below follow that order. Each one is free, with no account to create, and written to be read straight after the previous one.
If you are starting out, begin with market structure and skip nothing. Half the mistakes made on order blocks come from structure misread upstream, not from the order block itself.
If you already know the vocabulary, the structure and liquidity lesson is the one that adds the most: it explains the order-book mechanism behind the terms, which most ICT courses leave out.
