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.

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.

Data source: Binance spot + futures
Confirmed at: 3+ touches
Statuses: Near · Broken · Fail · Retest
Break rule: Closed candle + ATR margin

Dominant lines

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.

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.

Near. 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.

Line status, tracked live

Near

closed-candle confirmed

Price is pressing into the line's margin — a test is underway, no break yet.

Broken

closed-candle confirmed

A closed candle has pushed clean through the line, past an ATR-scaled margin.

Failed

closed-candle confirmed

The break closed back across within a few bars — a trap, not a real move.

Retest

closed-candle confirmed

Price returned, tested the flipped line and held it — the highest-quality entry.

Retest = support flipped to resistance (or the reverse) 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.

01Fit the line. Swing pivots are found, and the dominant support and resistance lines are fitted through them — the ones with the most touches, tightest fit and freshest structure.

02Count the touches. Each touch is measured with a volatility-aware margin: max of a fixed percentage and an ATR-scaled band, so a calm coin isn't held to a wild coin's tolerance.

03Confirm the break. A break waits for a candle to close beyond the line past the margin. Close back across within a few bars and it becomes a failed break — a warned trap.

04Catch the retest. After a confirmed break, a held pullback into the flipped line's band is surfaced as a retest — support becomes resistance, or the reverse, and price respected it.
