Trendlines, drawn the way a chartist would.
CoinBeacon fits the dominant support and resistance lines through a coin's swing pivots on Binance spot and futures — then validates each one by how many times price has touched it. Three touches or more reads as trustworthy. You get the lines, not a blank chart.

The two lines that actually matter.
A chart can support a dozen overlapping lines. CoinBeacon keeps the one dominant support and the one dominant resistance a trader would actually mark — ranked by quality and de-duplicated so you're never staring at noise.
- Validated by touch count. Three or more pivot touches marks a line confirmed; a two-touch line shows as developing so you know it's early.
- Quality-scored. Each line is scored on touch count, how far its touches span the window, how tightly price hugs it, and how recent the last touch is.
- Fresh structure wins. Lines price has moved on from decay in the ranking, so the levels you see describe the market now — not last month.
- Rising, falling or flat. Each line is labelled by direction, so a sloping trendline is never confused with a flat range.

Top-ranked by line quality
It watches the line so you don't have to.
Drawing the line is half the job. CoinBeacon tracks what price does at it — the difference between a real breakout, a trap, and the cleanest entry a flipped line offers.
- Testing. Price is inside the line's margin and testing it — you're watching a decision point, not a done deal.
- Broken, on a close. A break only counts when a candle closes beyond the line past an ATR-scaled margin — no single wick flips the status.
- Failed break flagged. If a break closes back across within a few bars, it's re-labelled a trap so you're not caught chasing a fakeout.
- Retest = role flip. When price returns to a broken line and holds it — support turned resistance, or the reverse — that's the highest-quality entry, called out for you.
The five line statuses
The vocabulary, not a reading — how many lines are in each right now is on the live board below.
Watching
The line is fitted and graded, and price is nowhere near it yet — most lines on the board sit here.
Testing
Price is pressing into the line's margin — a test is underway, no break yet.
Broken
A closed candle has pushed clean through the line, past an ATR-scaled margin.
Break failed
The break closed back across within a few bars — a trap, not a real move.
Retest holding
Price returned, tested the flipped line and held it — the highest-quality entry.
Every change between them is read on a closed candle · retest = the line flipped role and held
Why the retest is the entry.
A break tells you the level gave way. The retest tells you it flipped roles and the market accepted the new price. Pair trendlines with chart patterns and key levels to confirm it.
Inside the app
Trendlines, drawn for you.
The detector fits the dominant support and resistance lines through a coin's swing pivots, then watches each one live. This is the real board, on the same feed as the card above — one row per coin, ranked by line quality: the strongest line on each of the top 12 coins, out of 2,584 trendlines it is tracking on Binance spot right now.

Four steps, no drawing tool
How to use trendlines in crypto trading without drawing one yourself.
- 01Open the detector and pick the marketBinance spot, Binance futures, or both at once — with USDT or BTC as the quote. The lines arrive already fitted through the coin's swing pivots, so there is no drawing tool to argue with.
- 02Choose the timeframe you trade15m, 1h, 4h, 1D or 1W, and you can hold several selected at the same time. A 15-minute line describes this session; a weekly line describes the trend everyone else is watching.
- 03Filter to the lines you care aboutSupport only or resistance only, rising, falling or flat — or search a single coin by name. What is left is ranked by quality, so the lines with the most touches and the tightest fit sit at the top.
- 04Read the status, then act on the closeEach line carries one of five statuses — watching, testing, broken, break failed or retest holding — and every change between them is decided on a closed candle rather than a wick. Wait for the status you actually trade; for most people that is the retest, not the break.
What the lines are for
Breakouts, fakeouts, rising support and the line you forgot you drew.
Trendline breakout trading, with the participation check
A break of falling resistance is only worth acting on when someone shows up to buy it. The status turns broken on a close past an ATR-scaled margin, and a volume alert on the same pair tells you whether the move had real size behind it — sent to Telegram, Discord, email or a webhook.
Rising support under a coin you already hold
An uptrend that keeps respecting the same rising line is a position you can leave alone. The touch count tells you how many times it has held; when you want the exact number instead of the slope, put a price alert just under where the line will sit tomorrow.
Spotting the failed break before you chase it
Most trendline losses are traps — a clean-looking break that closes back across two bars later. That reversal is labelled a failed break rather than quietly dropped, and momentum turning at the same line often shows up first as an RSI or OBV divergence.
Trendlines as one leg of a confluence read
One line on its own is a hint. A trendline break sitting on top of a pattern and a volume expansion is a case, and that is exactly the kind of stack Smart Setups assembles for you across the market — with the trendline break counted as one of the confirmations, not the whole argument.
Trendlines — common questions
- How does CoinBeacon decide a trendline is trustworthy?
- By touch count. A line that swing pivots have touched three or more times is marked 'confirmed'; a two-touch line is flagged 'developing' and carried at half weight. Lines are also scored on how far their touches span the window, how tightly price hugs them, and how recent the last touch is.
- When does a trendline count as broken?
- Only when a candle closes beyond the line by more than an ATR-scaled margin — not on a single intrabar wick. If a confirmed break closes back across the line within a few bars, it is re-labelled a failed break, so you are warned about traps instead of chasing them.
- How do I draw trendlines on a crypto chart automatically?
- You don't draw them — CoinBeacon fits them. The detector finds a coin's swing pivots and fits the dominant support and resistance lines through them, then ranks the candidates by quality and collapses near-duplicates so one support and one resistance survive per chart. Open the detector, pick the market and timeframe, and the lines are already on the chart.
- What is a trendline retest, and why do traders wait for it?
- A retest is price coming back to a line it has already broken and holding it — support that flipped to resistance, or the reverse. It matters because a break alone only says the level gave way; the retest says the market accepted the new price and the roles really did flip. CoinBeacon flags it as its own status, with how many bars ago the retest touch happened.
- Which exchanges and timeframes do the trendlines cover?
- Binance spot and Binance futures, on USDT and BTC quote pairs. Five timeframes are available — 15m, 1h, 4h, 1D and 1W — and you can hold several selected at once, so a line forming on the 4-hour sits beside one on the daily. This detector is Binance-only; it isn't a multi-exchange price feed.
- What's the difference between a trendline and a horizontal key level?
- A trendline slopes — it tracks a level that rises or falls with the trend, so its price changes every bar. A key level is flat: a pivot, a Fibonacci retracement, a round number or an old swing high that sits at one price. Traders use both, and the strongest reactions tend to come where a sloping line and a horizontal level meet.
- Do the trendlines repaint or change after the candle closes?
- Touches, breaks and retests are read on closed candles only, so a status doesn't flip because of an intrabar wick. A break needs a close beyond the line by more than an ATR-scaled margin, and a break that closes back across within a few bars is relabelled a failed break. The line itself is refitted as new pivots print — that is the structure updating, not a signal rewriting itself.
- Is the trendlines detector free to use?
- Yes. The free plan includes every CoinBeacon feature, the trendlines detector included, with up to 5 active alerts and 10 notifications per day. Trendlines are drawn on Binance spot and futures market data. Sign in with Google to start.
