Smart money and liquidity — the terms in plain language

By Najm FX (NFX) · 8 min read · Analysis · Published

Short answerSmart money rests on one idea: large orders need liquidity, and liquidity pools above highs and below lows where people place their stop losses. Every term comes from that: a liquidity sweep (a fast break and a return), an order block (the last opposite candle before a strong move), BOS and CHoCH (are the highs and lows still moving the same way), and FVG (a price gap). Their main limit is that they read beautifully in hindsight.

Smart money concepts are everywhere now, and they come with intimidating English terms: Order Block, BOS, CHoCH, FVG. The idea behind them is simpler than it looks — here we explain it in ordinary language, and we also say where it fails.

The core idea in one sentence

Large orders (banks and institutions) cannot be filled in one go without moving price against themselves. So they need liquidity — opposite orders to fill against. And where opposite orders gather is well known: above highs and below lows, because that is where people place their stop losses.

Every other term describes this same idea from a different angle.

1. Liquidity — where it pools

When there is a clear high on the chart, above it you will find:

  • Stop losses of people who are short (which are buy orders).
  • Pending buy orders from people waiting for the breakout.

So above the high there is a cluster of buy orders. The same is true below a low, where sell orders gather. These places are the "liquidity pools".

2. Liquidity sweep (stop hunt)

You see price break the high with one fast candle, poke slightly above it, then drop back down hard. That is what is called a sweep.

What actually happened: the break triggered the buy orders stacked above the high, and those orders gave the other side the liquidity it needed to sell in size. After that, price reverses.

How to recognise it: a candle with a long wick above the high and a close back below it. A wick — not a close above the level.

3. Order block

The last opposite candle before a strong move. Example: one bearish candle, followed by 5 strongly bullish candles. That bearish candle is the "order block".

The logic: this is the exact area where the large orders entered. When price returns to the same area later, traders expect a reaction — either a bounce or a continuation.

In practice: you mark the area (the candle body, or the whole candle) and watch how price behaves when it comes back. It is not a blind entry order.

4. Break of structure (BOS) and change of character (CHoCH)

  • BOS — Break of Structure: the market is rising (higher highs and higher lows) and it breaks a previous high. It means the trend is continuing.
  • CHoCH — Change of Character: the market is rising and for the first time it breaks a previous low. It is an early signal that the trend may be turning.

Both are just an organised way of describing something simple: are the highs and lows still climbing, or have they started to fall?

5. Fair value gap (FVG)

When price moves very fast it leaves a "void" — an area where price did not trade enough. You see it as a gap between the wicks of 3 consecutive candles.

The idea is that the market tends to come back and fill that void later. It is used as an area to watch for an entry.

Straight talk: where these concepts fail

These are reading tools, not guaranteed rules. Two observations matter most:

  • Hindsight interpretation. On an old chart every order block looks perfect — because you can see what happened after it. In the live moment there are dozens of candidate areas and you do not know which one will work.
  • Subjectivity. Ten traders will draw the order block in ten different places. There is no single mathematical definition.

That is where indicators in this space help: they draw the areas by a fixed rule, which removes the subjectivity. But you still need your own decision — who says this area will work this time?

How to start practically

  1. Install a liquidity or market-structure indicator on a demo chart.
  2. Watch for a week without trading. Record: how many times price reacted at the area, and how many times it went straight through.
  3. Only then, and with the smallest size, try it on a real account.

Smart money concepts help you understand "why" price moved — and that is valuable. But they do not remove risk, and no method of analysis wins every time.
