Trading Roadmap | Gann · Lesson 04 — The 1×1 AngleEthereum / TetherUSBINANCE:ETHUSDTBigBelugaLesson 04 - The 1x1 Angle Difficulty: (Intermediate) Gann called this the most important line on any chart, and most people draw it wrong within thirty seconds — because the line is not an angle at all. It is a rate, and a rate has no meaning until you decide what one unit of price and one unit of time are. This lesson is about making that decision properly, reading the single thing the line tells you, and knowing the moment it stops being worth having on the chart. One line, one rate, three separate occasions on which price came back to it and went no further. Nothing about the line changed between those three touches — it was fixed the moment the low was chosen and the unit was set. 🔵 QUICK RECAP FROM LESSON 03 Lesson 03 introduced the fan and the family of rates around the reference: 2×1 and 4×1 steeper, 1×2 and 1×4 shallower. Everything in that family is defined relative to one line. This lesson takes that line on its own. 🔵 1. WHY THIS ONE LINE The 1×1 is the only member of the fan that is not described in terms of something else. It is the reference the others are measured against. - Every other angle is a multiple or a fraction of it - A market above it is advancing faster than the reference rate, below it slower - It is the only line in the toolkit that can be set once and read for months Gann's preference for it was strong enough that much of his written work treats the other angles as secondary. Whether that ranking is justified is debatable; what is not debatable is that a fan with a badly chosen 1×1 is wrong in every one of its lines at once. 🐳 Pro Tip: Get this line right and the rest of the fan is arithmetic. Get it wrong and no amount of care with the other angles can rescue it. 🔵 2. THE UNIT IS THE WHOLE METHOD A 1×1 rises one unit of price for one unit of time. Until you say what those units are, the line is undefined — and this, not the drawing, is where the work is. One practical way to set it. Take a swing the market clearly produced — the brackets mark its price range and the bars it took — and divide the one by the other. That quotient is the rate the market was moving at. Extended forward from the high, the same rate catches the pullback that follows. Three defensible ways to choose a unit, in order of how much they rely on judgement: - From a known swing — range divided by bars, as above. The market chose it, not you - From average range — the typical bar range over a long lookback, which keeps the unit tied to current volatility - A round number per bar — simple and repeatable, and the weakest of the three, because nothing about the market suggested it Whichever you choose, the unit has to be written down and kept. A line drawn with one unit and later read as though it had another is not measuring anything. 🐳 Pro Tip: Fix the unit per instrument, not per chart. The same market on two timeframes needs two units, and mixing them is the most common silent error with this tool. 🔵 3. THE ONE READING IT GIVES A correctly set 1×1 answers exactly one question, and it is worth being clear that it answers only that one. The same line through a full cycle. On the left price is above it, returning to it and holding — the advance is keeping pace with the reference rate. On the right it has crossed below and stays there: the trend continues in the same direction but no longer at that speed. The marker is the bar the two swapped places. - Above the line — the market is advancing at or faster than the reference rate - Below the line — the advance has slowed relative to it - Crossing it — the rate has changed, which is a statement about speed and not about direction That last distinction is the one people lose. A market can lose its 1×1 and keep making higher highs for months. It is travelling more slowly, which is information, and it is not a reversal. 🐳 Pro Tip: Write "speed" next to the line when you draw it. It stops you reading a crossing as a signal about where price is going. 🔵 4. THE SAME LINE FROM A HIGH Nothing about the method changes for a decline. A 1×1 falling from a high at the same rate, with price beneath it. The rallies come back to the line and fail there. The unit is identical to the one used in the advance — only the anchor and the direction changed. - Anchor on the high and fall at one unit of price per unit of time - Price below it means the decline is keeping pace; above it means the decline is slowing - Use the same unit you used upward, or the two readings cannot be compared 🐳 Pro Tip: Drawing both — one from the last major low and one from the last major high — is often enough. Two lines say more than a full fan and leave the chart readable. 🔵 5. WHAT A BADLY CHOSEN UNIT LOOKS LIKE This is the failure mode worth recognising on sight, because the chart tells you immediately. Two candidate lines from the same low. The faint one uses a unit far larger than the market's own pace, and it leaves price behind within a few bars — it can never be touched, so it can never be wrong, so it says nothing. The other was fitted to a real swing, and price keeps returning to it. - A line price never reaches is not a conservative line, it is an empty one - A line price crosses constantly in both directions is the same problem in reverse - A useful 1×1 gets touched, holds sometimes and fails sometimes The test is simple and can be applied in a few seconds: look back over the last few months and count the touches. None at all means the unit is wrong. 🐳 Pro Tip: Three to six meaningful touches over a trend is roughly what a well-chosen unit produces. Zero or twenty are both telling you to set it again. 🔵 6. WHEN THE LINE EXPIRES A 1×1 does not last forever, and it does not announce its own end. A line that worked for the whole first half, then a break that took price far below it. The line carries on rising at the same rate while price makes no attempt to follow. From that bar onward it is measuring a market that no longer exists. - After a violent break or a gap, the old anchor rarely survives - Over long horizons a rising line eventually asks for prices outside the market's range - A change in the instrument itself — a different regime of volatility — invalidates the unit The discipline is to remove it rather than to keep hoping. A line nobody is respecting is clutter that makes the next correct line harder to see. 🐳 Pro Tip: Give every 1×1 an expiry condition when you draw it: a level that, if broken, means the line comes off the chart. Deciding that in advance is much easier than deciding it afterwards. 🔵 7. WHY 45 DEGREES KEEPS COMING BACK The phrase is everywhere, so it is worth closing the loop on it. A 1×1 appears as 45 degrees on screen only when one unit of price is drawn at the same pixel height as one unit of time is drawn wide. That is a property of your zoom level, and it changes every time you scroll. - Setting a chart so the line looks like 45 degrees is working backwards from an appearance - Log scale bends the line, because equal price steps are no longer equal distances - Auto-scaling silently changes the picture every time a new high or low prints None of this affects the relationship the line describes. It affects only how it looks, which is why the unit is the thing to record and the angle is not. 🐳 Pro Tip: If you need the visual angle to be stable, fix the price scale manually and leave it. Otherwise ignore the angle entirely and trust the unit. 🔵 8. A DISCIPLINED WAY TO USE IT - One unit per instrument, derived from a real swing and written down - One line from the last major low, and optionally one from the last major high - Anchored exactly on the extreme - Read as speed, never as direction - Judged by touches — no touches means the unit is wrong - Removed when the move that produced it is over Used this way, the 1×1 is the cheapest trend-health check available: one line, no parameters to tune afterwards, and a reading that most indicators cannot give. 🐳 Pro Tip: Keep it next to a level tool rather than next to another trend tool. It measures rate, and pairing it with something that measures price is what makes the combination worth having. 🔵 COMMON MISTAKES - Drawing the line before deciding what one unit of price and one unit of time are - Adjusting the zoom until the line looks like 45 degrees - Using one unit on the daily chart and a different one on the four-hour, then comparing - Reading a crossing as a reversal rather than as a change of speed - Keeping a line that price has not touched in months - Leaving old lines on the chart after their move has ended - Switching to log scale and assuming the line still means the same thing 🔵 QUICK SELF-CHECK - Pick one instrument and write down its unit: how much price per bar, and why that number - Draw one 1×1 from the last major low and count how many times price has touched it - Find the bar where price crossed the line and ask what happened to speed, not to direction - Draw the mirrored line from the last major high with the same unit - Change your vertical zoom, watch the angle change, and confirm the touches did not 🔵 WHAT IS NEXT Lesson 05 takes the same unit and builds a grid from it: the Gann Grid, where the horizontal and vertical spacing both come from the choice made in this lesson, and price and time are measured on the same chart at the same time. Worth sitting with before then: the hardest part of this tool is not drawing the line. It is being willing to take it off.
