Key Points
- Trendlines in technical analysis are simple guides that connect swing points to show direction and pace in a crypto move.
- To draw trendlines in crypto, start on a higher timeframe, anchor to clear swing highs or lows, then refine on a lower timeframe.
- A usable trendline usually needs two anchors and a third touch or clean reaction to confirm it matters.
- Trendline breaks and retests are more reliable when a close breaks the line and the retest holds or rejects with clear follow-through.
- Most trendline mistakes come from forcing lines, drawing them too steep, or changing them constantly to fit price.
- If any terms feel unfamiliar, use the Crypto Glossary for quick definitions, then return to this lesson.
Quick Answer
A trendline is a diagonal line that connects swing lows in an uptrend or swing highs in a downtrend to show where price has repeatedly reacted. To identify trendlines, use obvious swing points, draw the line with at least two anchors, and treat the line as a guide that becomes more meaningful after repeated reactions.
Where This Lesson Fits
Lesson 6 taught you how support and resistance levels mark horizontal price zones where reactions repeat. Lesson 7 adds diagonal context by showing how trendlines capture the slope of a move, helping you recognise whether a trend is accelerating, slowing, or breaking down.

What A Trendline Is In Technical Analysis
Trendlines are not predictions. They are a visual way to describe how price has been moving.
A trendline helps you answer three practical questions:
- Is the market moving up, down, or drifting sideways?
- Is the pace of the move steady or changing?
- Where has price repeatedly reacted along that slope?
If you can draw a line and price respects it more than once, the market is showing you a repeatable behaviour.
Uptrend Trendlines Vs Downtrend Trendlines
Uptrend trendline: connect higher swing lows
- Price keeps finding buyers at rising levels
- The line acts as a rising guide for pullbacks
Downtrend trendline: connect lower swing highs
- Price keeps finding sellers at falling levels
- The line acts as a falling guide for relief rallies
How To Draw Trendlines In Crypto
Use the same process every time.
Step 1: Start On A Higher Timeframe
Start here: daily first, then weekly if the move is long-term.
Higher timeframes reduce noise and make your anchors clearer.
Step 2: Choose The Right Anchor Points
Anchor points should be: obvious swing highs or swing lows that led to a clear move away.
- For an uptrend line, use swing lows that caused a strong push up
- For a downtrend line, use swing highs that caused a clear drop
If you have to squint to justify the anchor, it is not a good anchor.
Step 3: Draw The First Line With Two Anchors
Two points create the line. This is the “candidate” trendline.
Step 4: Look For A Third Touch Or Clear Reaction
A third touch does not guarantee anything, but it increases usefulness. It suggests the line is visible to more participants.
A clean reaction looks like: price approaches the line, stalls, then moves away with purpose.
Step 5: Refine On One Lower Timeframe
After setting the main trendline on the daily:
- Drop to four-hour or one-hour
- Check if the same slope fits reactions more cleanly
- Avoid overfitting the line to every wick
Bodies Or Shadows, What Should You Use?
Crypto can sweep obvious levels. That is why trendlines work best as guides rather than perfect barriers.
A practical rule is: prioritise the best “fit” for repeated reactions, then let a little overshoot happen.
- If most reactions happen on candle bodies, draw closer to bodies
- If repeated sweeps happen but closes respect the same slope, give more weight to closes
How To Identify Trendlines Without Forcing Them
Many beginners draw too many lines, then assume the market “respects” all of them.
Use this filter: if the line only works after you adjust it every time price moves, it is not a trendline, it is a drawing.
Keep trendlines that:
- connect clear swing points
- show repeated reactions
- remain stable without constant edits
Trendline Breaks And Retests
Trendline breaks and retests are one of the most common ways trendlines are used.
A simple sequence looks like:
- price respects the line multiple times
- price breaks the line
- price revisits the area near the line
- price either holds it (trend continues in a new phase) or rejects it (old slope fails)
What to prioritise:
- a close beyond the line, not just a quick spike
- follow-through after the break
- how price behaves on the retest, does it hold or reject cleanly?
A break without follow-through is often just noise.
When Trendlines Fail Most Often In Crypto
Trendlines fail because crypto is volatile and liquidity can be thin.
They also fail because of avoidable mistakes.
Common trendline mistakes include:
- drawing the line too steep, so it cannot realistically hold
- using tiny anchors on a low timeframe and treating them as major signals
- ignoring major horizontal support and resistance zones nearby
- treating one touch as proof
- assuming every break is meaningful without checking closes and follow-through
A Simple Checklist For Trendlines For Beginners
If you want a quick process you can repeat:
Mark:
- the trend direction on the daily chart
- the two clearest swing points for a candidate trendline
- the next obvious horizontal level above or below
Check:
- whether price has reacted at least twice, preferably three times
- whether closes respect the line more than random spikes
- whether the line still makes sense without constant edits
Then:
- watch how price behaves as it approaches the line again
- if it breaks, watch for retest behaviour before you assume the slope is finished
Mini FAQs
What is a trendline in technical analysis?
A trendline is a diagonal guide drawn by connecting swing lows in an uptrend or swing highs in a downtrend to show the slope of a move.
How to draw trendlines in crypto?
Start on the daily chart, pick obvious swing points, draw a candidate line with two anchors, then look for a third touch or clear reaction and refine on a lower timeframe.
How to identify trendlines without forcing them?
Use clear swing anchors and keep only lines that remain stable without constant adjustment. If you must keep redrawing it, it is not reliable.
How many touches confirm a trendline?
Two touches create the line. A third touch or clean reaction makes it more meaningful because it suggests repeated market behaviour.
What is a trendline break?
A trendline break is when price closes beyond the line and shows follow-through, suggesting the prior slope is no longer being respected.
What are trendline breaks and retests?
After breaking a trendline, price often revisits the line area. If it holds, the market may continue in a new phase. If it rejects, the old slope often becomes resistance or support.
Why do trendlines fail in crypto?
High volatility, liquidity sweeps, and poor anchor selection can break trendlines. Using higher timeframes and focusing on closes reduces false signals.
