Ask most traders what a trend line is for and they'll say the same thing: it shows you the trend. And they're not wrong. But that answer also reveals the problem.
Showing you the trend and generating a trade are two completely different things. And most of the time, the way trend lines get drawn and used, they do the first job and completely ignore the second.
I've been trading since 1993 — the floor, brokerage, prop, hedge fund investment committees, running my own fund. In all of that time, I've developed one core conviction about trend lines: a trend line that doesn't tell you where to enter, where to stop out, and where to take profit is just a line. It's decoration.
What I use is what I call the trade trend line. Same two words, very different application. Here's the complete framework.
The textbook approach — technical analysis literature going back to the 1960s — teaches that three points are required to define a valid trend line. Two points draw the line, and the third point confirms it.
I push back on this. Not because it's wrong as a description of a trend, but because of what it fails to give you as a trader.
Problem One: You Already Know the Trend
By the time you have three confirmed touches of a trend line, you are well into the move. The trend has been established for long enough that you don't need a line to show it to you — you can see it with your eyes. If a stock has been making lower highs and lower lows for weeks, a downward sloping line connecting the highs isn't telling you anything you didn't already know.
The line is visual confirmation of something obvious. That's fine for a textbook diagram. It's not particularly useful for someone trying to make a trade decision.
Problem Two: You Don't Have a Trade
This is the bigger issue. A three-point trend line gives you a zone — an area where price has reacted before. The typical use case is to sell against a downtrend line as resistance, or buy against an uptrend line as support.
But consider what you're missing: What is the exact entry? Is it the trend line touch itself? A close above or below? What is the stop? Where is the target? Without those three elements defined before you enter the trade, you don't have a trade. You have an idea with no structure around it.
Every trade I take has a concrete entry signal, a defined stop, and a specific target — all determined before I put the position on. The three-point trend line, used as support or resistance, rarely provides all three.
My trend lines use exactly two points. Each point has a name and a function:
The initiating point — where the trend line starts. This is the origin of the move I'm tracking.
The defining point — the second touch that establishes the line's angle and direction.
Two points. That's all I need. And here's the key: I'm not drawing this line to show me a trend. I'm drawing it to define a trade that will be generated when the line is broken.
What I'm Looking for When the Line Breaks
A close above (for a downward trend line) or below (for an upward trend line) is the signal I'm watching for. But the close alone isn't enough. Here's my full entry sequence:
If price closes through the line but collapses back to the other side the very next day, the line has not been genuinely broken. In that case I redraw: the defining point shifts to the most recent relevant high or low, and the trend line continues in an updated form.
This is what I mean when I say trend lines are living. They evolve as price evolves. A redraw isn't a failure — it's the process working correctly. The question I'm always asking is whether this trend has genuinely shifted or whether it's just testing a level before continuing. The close and the follow-through answer that question.
Why Two Points Work Better Than Three
There's a subtle but important implication here. If you're using the traditional three-point system and you decide to sell on the third touch, you're actually using a two-point trend line — because before the third touch happens, you only have two confirmed points. The third point is what makes the traditional trend line valid. If you're trading before it's confirmed, you're using my framework whether you realise it or not.
The difference is I'm explicit about it. I know I'm using two points. I know exactly what that means for my entry, my stop, and my target. And I'm not waiting for a third confirmation I don't need.
First Target: The Defining Point
Once I have a valid break and entry signal, my first target is always the defining point of the trend line.
This is where the geometry of the two-point system earns its place. The defining point is a prior significant price level — it's the touch that gave the trend line its direction. When price reverses and breaks the trend line, that prior level becomes the natural first target for the move. It's not arbitrary. It's not a guess based on a round number or a previous swing. It's structurally embedded in the pattern itself.
In our live session, I demonstrated this on a large US consumer technology company's chart. A downward trend line had been broken with a close above it. The defining point — a prior high that had defined the line's angle — was clearly visible on the chart. That became the target. Price moved toward it, reached it, and the trade was complete. The geometry did its job.
Second Target: The Initiating Point Body
If price breaks above the defining point as well, the target extends further — to the body of the candle that forms the initiating point. Specifically, the open or close of that candle, not the wick.
The reason I use the body rather than the actual high or low is practical: initiating points are often near significant extremes — prior all-time highs, major breakout levels, long-term resistance points. The wick of those candles can be very difficult to reach, and targeting them can result in premature exits or unrealistic expectations about where price is going.
The candle body is the more achievable, structurally relevant level. I've found it to be a more reliable target in practice over many years of applying this framework.
When and How to Redraw
The most common question I get about this framework is: when do you redraw?
The answer is straightforward. If price closes through the trend line but reverses back to the other side on the very next session, the line is not broken. I redraw it: the defining point moves to the most recent relevant extreme, and the trend line continues at a new angle.
As this happens repeatedly, the trend line typically gets flatter. And that flattening is information in itself — a flattening trend line tells me the trend is weakening. The move is losing momentum. That doesn't mean a reversal is imminent, but it means the conditions are changing and I need to be alert.
What I don't do is abandon the trend line entirely just because it's been redrawn several times. The redraw is part of the methodology. I keep the current trend line and I ignore the historical ones — they've done their job. What matters is the one that's active right now.
Kissing the Trend Line Goodbye
After a genuine break — a close through and a follow-through session — price will sometimes pull back toward the broken trend line before continuing in the direction of the break. I call this kissing the trend line goodbye.
It happens more often than people expect. The reason is that when a trend line is broken, some of the traders who were positioned with the trend will exit, and some contrarian traders will try to fade the break. That activity can push price back toward the line temporarily. When the buyers (or sellers, depending on direction) who believe in the break hold firm, price rejects from the line and continues.
A kiss is not a failure. It is a retest that holds. And for traders who missed the initial entry on the break, it is frequently a second — and often cleaner — entry opportunity. The risk-reward on a kiss entry can actually be better than the initial break entry, because the broken trend line is now a confirmed level of support or resistance, and the stop can be placed just on the other side of it.
The Hierarchy
My preference for applying the trade trend line framework follows the same hierarchy I apply to every other pattern:
More data behind a signal means more weight behind that signal. A weekly trend line break has required many more sessions of price action to form than a four-hour break. The signal carries more information. In my observations over many years, weekly trend line breaks have been more reliable in reaching their defined targets than shorter-timeframe breaks. That said, past results are not indicative of future performance, and no pattern guarantees a particular outcome.
Using Lower Timeframes to Fine-Tune Entries
Here's a specific application I use regularly: fine-tuning a higher-timeframe entry using a lower-timeframe trend line.
Let's say I have a strong daily setup — a rotation zone or a pattern I'm confident in — but the daily close is still several hours away and I'm concerned the entry level is moving away from me. I'll drop to a one-hour chart and look for a trend line break in the direction of my daily signal. If the one-hour trend line breaks cleanly and I get my follow-through, I'll enter on the one-hour close, effectively getting into the daily trade a few hours early.
The critical discipline: if the daily close arrives and the daily signal has not confirmed, I exit the position. The one-hour entry was a fine-tuning mechanism — it was not a replacement for the daily signal. The higher timeframe remains the framework. The lower timeframe is only the entry tool.
This distinction matters. The temptation when you're watching a one-hour chart closely is to start treating the one-hour as your primary signal. That's the wrong direction. Know which timeframe you're trading and which timeframe you're using to enter. They are not the same thing, and conflating them is one of the more common ways active traders erode their edge.
In our live session, I pulled up charts for several well-known stocks and walked through the trade trend line framework on each. A few observations worth carrying forward:
On automated trend line tools: Several charting platforms now have features that automatically draw trend lines across price data. These can be useful for scanning — they'll highlight where multiple touches have occurred. But they don't give you the trade trend line framework. They give you the traditional three-or-more-point lines, and they don't define the initiating point, the defining point, or the targets. Use them to find candidates. Don't use them to find trades.
On aligning trend lines with moving averages: When a trade trend line break coincides with a close above or below a major moving average — particularly the 200-day — the signal carries more weight. Two independent levels confirming at the same point is meaningful. Neither one caused the other. They're both responding to the same price structure, and their convergence strengthens the case for the trade. That said, convergence is context — not a guarantee of outcome.
On very long-term trend lines: You can draw trade trend lines going back to the earliest available price data on a chart. For long-established companies, that might be decades of history. I've done this.
The exercise is useful not for generating trades from ancient history, but for understanding which trend lines are currently active and which have already resolved.
You're always looking for the two that matter right now: the most recent active uptrend line and the most recent active downtrend line. Everything else is historical context.
