There is a temptation, when you start, to look at a chart and ask it where price is going next. Resist this. First learn to describe, in plain words, what is already there. Today we learn the vocabulary.
§1Why structure, and why now.
In the previous lessons you learned to read a single candle, then a sequence of candles, then the role of volume. We have been zooming out. Today we zoom out one final notch and look at the chart as a whole — its structure.
Market structure is the simplest, oldest, and most reliable lens in technical analysis. Long before there were indicators, before there were even charts as we know them, traders watched for one thing: were prices making higher highs and higher lows, or were they making lower lows and lower highs?a That is essentially the whole idea. Everything else this lesson teaches is a refinement of that single sentence.
A market is in one of three states: trending up, trending down, or doing neither. Most of the time, it is doing neither.
It is worth stopping here. Most retail traders lose money because they trade during the "doing neither" state as if it were a trend, and trade during a trend as if it were noise. Learning structure is, more than anything, learning to tell which of these three states you are looking at — and being honest with yourself when you cannot tell.
§2Highs and lows, the only vocabulary you need.
The four words that follow will appear in every subsequent lesson. Memorise them — not as jargon, but as plain descriptions of a shape.
- Higher high (HH) — a peak that is higher than the previous peak.
- Higher low (HL) — a trough that is higher than the previous trough.
- Lower high (LH) — a peak lower than the one before it.
- Lower low (LL) — a trough lower than the one before it.
An uptrend, by definition, is a sequence of higher highs and higher lows. A downtrend is a sequence of lower highs and lower lows. A range is everything else: highs and lows oscillating around the same levels.
You will hear sophisticated-sounding variations of this — "BOS" (break of structure), "CHoCH" (change of character), "MSS" (market structure shift). They are all the same idea dressed in different acronyms. The acronyms are not the lesson. The shape is.
§3The break.
A break occurs when price decisively closes beyond a previous structural high or low. The word that matters in that sentence is decisively. Price pokes through highs and lows constantly; a true break has follow-through, often on elevated volume, and is sustained on the next bar.b
Most false breakouts look identical to true ones until the bar after. This is why we wait for the bar after. The cost of waiting is one bar of "missed move." The cost of not waiting is most of your account, over time.— from Stage 3, Lesson 3.2
When the break is to the upside in what was a range, we call it a breakout. When the break is in the opposite direction of an existing trend, we call it a break of structure — the first piece of evidence that the trend may be ending. Note the word "evidence." Not proof.
§4The retest, and why it matters.
After a break, price often returns to test the broken level from the other side. What was once resistance now acts as support; what was once support now acts as resistance. This is not a mystical phenomenon — it is mechanical. Limit orders placed at the old level, plus the memory of traders who acted there before, plus the same humans showing up again with the same emotions, conspire to make the level matter twice.
The retest is a gift to the patient trader. It provides:
- A second chance to enter, often at a better price than the break itself.
- A clearer place to put a stop loss — just beyond the retested level.
- Confirmation: a retest that holds is strong evidence the break was real.
Which of these is the strongest evidence that a breakout is real?
§5A worked example.
Below is a four-month stretch of Bitcoin's daily chart. Read it from left to right and look for the shape we have just named: a range, a break, a retest, a continuation. Do not look at the annotations until you have looked at the chart itself for at least sixty seconds.
Notice what the annotations do not tell you. They do not predict what happens next. They describe what already happened. This is the whole practice — first describe, then (sometimes) anticipate, only ever probabilistically.
§6Common mistakes.
I have made all of these. The first six months of your practice will likely contain most of them.
- Calling everything a trend. When in doubt, the market is in a range. The default answer is "doing neither."
- Trusting the first break. First breaks fail roughly half the time. Wait for the retest, or accept that you are betting on a coin flip.
- Drawing structure on too small a timeframe. What looks like a break on the 5-minute chart is often noise inside a range on the hourly. Always zoom out before you act.
- Forcing structure where there is none. Some charts are genuinely uninterpretable. The professional move is to say "I don't have an opinion on this one" and look at the next chart.c
§7Practice.
Now you go and do it. Open the chart trainer and mark up ten charts: identify the most recent structural high and low, decide whether the chart is in an uptrend, a downtrend, or a range, and rate your confidence honestly. We are training the muscle of describing what is in front of you. The trades come later.
A note on certainty. Nothing in this lesson is a guarantee. The shapes described here will fail in your own trading, sometimes spectacularly. That is the nature of probabilistic edges. Stage 3 teaches you how to size positions so that this is survivable, and why doing so matters more than any pattern you can name.
