Where the stops are, why price goes after them, and how to choose your target.
Liquidity is the fuel of the markets: it shows where the orders are, where price wants to go and how it gets there. Spotting FVGs, OBs and the rest is useful, but if you don't know which way the market is heading, it won't get you very far.
It is simple: price only does two things. It only has two objectives.
It all comes down to a simple sequence: ERL, IRL, ERL, IRL, and so on.

You can trade it both ways:
Many traders enter on a POI without knowing whether price is aiming for an IRL or an ERL, and exit too early, or hold too long. Always identify your target before entering, so you know where to take profit before the trade even starts.
In my view, trading IRL to ERL is easier than the reverse, because you are trading with the trend. Trading ERL to IRL means trading against it, and you are mechanically at a disadvantage. In that case, take profits faster.

One last, fundamental point: liquidity is fractal. What you see as an internal target on the H4 often contains its own complete structure on the M15, with its own external liquidity levels. In other words, internal liquidity on the H4 can very well be external liquidity on the M15. It all depends on the scale you are looking at.
Understanding this lets you build a clear directional bias, frame a scenario, and find consistent entries and exits, whatever the timeframe.

The rest is in the book
These pages are the first part of the book. The rest answers the two questions that matter: which pair to trade, and when to enter.
