Setting up the 24h turnover screener

The screener watches the dollar turnover of the last 24 hours and notifies you when it changes sharply. This is not the volume bars on your chart: candle volume is something the screener never sees.

Turnover shows how much money actually went through a coin. A price move without turnover usually means an empty order book rather than market interest. Below is a walkthrough of every field — click an item and it lights up in the form.

In short

The screener watches dollar turnover, not the volume bars on your chart: candle volume is something it never sees.
The form has three scenarios. One measures percent of the daily volume, the other two measure turnover over the last minute. That is the key distinction in this form.
The scenarios are independent: an alert arrives on whichever fires. The wash-trade filter sits on its own card and only checks the minute scenarios.
Where to start: apply a ready-made setup — say, a $3m-per-minute threshold with a daily turnover floor of $10m — and move the thresholds from there.

Scenarios

When should this screener fire?

2 of 3

Turnover change

Fires when 24h turnover changes by the specified % over the selected interval

Turnover per minute

Fires when turnover for the last minute (in USDT) crosses the threshold. It is estimated from the difference between consecutive 24h-turnover snapshots.

Spike vs average

Fires when one-minute turnover is N× its 20-minute rolling average. The multiplier is measured against the coin's own norm, so one value works for BTC and for thin coins alike.

Limits

Cap how often the screener may fire on a single coin

1 of 2

When on, limits how many alerts the same coin can generate, so you do not get dozens of notifications about the same move.

Adjust to the market

The screener moves the value within your range on its own: when alerts are too frequent — toward the top, when there are almost none — toward the bottom. Recomputed once a day from your alert flow. Your numbers stay as you set them; the value in effect is always shown here.

Filters

24h turnover screener trigger scenarios

The three scenarios are independent and answer different questions. What separates them is not strictness but what they compare against:

Scenario	Compared against	Threshold unit
Turnover change	daily volume now versus N minutes ago	percent
Turnover per minute	the last minute’s turnover versus your threshold	$m
Spike against the average	the last minute versus its own 20-minute average	multiplier

The first scenario measures percent of the daily volume, which makes its thresholds deceptive. An ordinary hour is roughly 1/24 of the daily volume, about 4%. Hence the conversion:

Threshold	Window	The hour traded roughly
4%	1 hour	twice an ordinary hour
15%	1 hour	4.5 times the usual
50%	1 hour	13 times the usual

The most universal of the three is the spike against the average. It compares minute turnover not with an absolute threshold but with the last 20 minutes’ average for the same coin, so one multiplier works equally on bitcoin and on a thin altcoin: each has its own normal level. If fewer than ten valid minutes are available in that window, the screener stays silent — an average built from scraps means nothing.

Limits: how many turnover alerts you are willing to read

One event gives one alert: the screener fires at the moment the threshold is crossed, not every minute while turnover stays above it. But the first abnormal minute is usually followed by several more, and each of them can cross the threshold again. Limits matter here even more than in the price screener.

Filters: which coins to measure turnover on

The spike multiplier alone does not protect you from junk: on a coin whose ordinary minute is two hundred dollars, a five-fold spike equals a thousand. The minimum daily turnover cuts such pairs before they ever reach the scenario. The arithmetic is plain: $10m a day is roughly $7k a minute.

The minimum open interest hides one trap. Open interest exists only on futures, so this floor combined with the spot-only market filter discards every spot pair and the screener stays silent. Leave it at zero when you want spot.

The wash-trade filter: what it checks

Wash turnover looks exactly like the real thing; what differs are its consequences. The filter looks at three of them over a 15-minute window: how much of the turnover turned into open positions, whether the price moved at all, and the ratio of the venue’s open interest to its own daily turnover. Real flow leaves a trace in all three; churning your own liquidity leaves none.

The outcome is one of three verdicts: clean, suspicious, wash. Soft mode drops only wash, strict mode drops suspicious too, and the “show suspicious” toggle brings them back into the feed with a badge. What gets dropped is a venue, not a coin: wash turnover on one exchange does not kill an honest spike on the same coin elsewhere. A spike there was nothing to verify against is never dropped.

One important limit: the filter only checks the minute scenarios — turnover per minute and the spike against the average. A change in daily volume over an hour or more is not a signature of wash trading, and a 15-minute window says nothing about it.

Ready-made setups

These are the same sets applied with one click in the screener settings. The values below are exactly what gets filled in.

Sustained turnover growth

An hour at double the pace

Period: 720 min.
Pause between alerts per coin: 360 min.
Adjustment range: 1.2%
Which market to watch: Spot and futures
Min. Exchange 24h Turnover: 50 M $

Logic: trading in the coin runs at roughly twice its usual pace for a whole hour — a sustained flow rather than a one-off spike. Liquid coins only: turnover from $50M, spot and futures. At most two alerts per coin in 12 hours.

Minute turnover from $3M

from $3M per minute

Per-minute volume threshold: 3 M $
Period: 240 min.
Pause between alerts per coin: 120 min.
Which market to watch: Spot and futures
Min. Exchange 24h Turnover: 10 M $

Logic: the coin's one-minute turnover goes above $3M. The threshold is 3M, not 1M: at 1M there were about twice as many alerts as is readable. Turnover from $10M, spot and futures, at most two alerts per coin in four hours.

Minute turnover up $5M+

$5M traded in one minute

Per-minute volume threshold: 5 M $
Period: 360 min.
Pause between alerts per coin: 180 min.
Which market to watch: Spot and futures
Min. Exchange 24h Turnover: 10 M $

Logic: in a single minute the coin traded five million dollars more than in the same minute a day earlier. A dollar threshold reads without any conversion. Turnover from $10M, spot and futures, at most two alerts per coin in six hours.

Minute turnover spike ×30

×30 vs a normal minute

Spike multiplier: 30 ×
Period: 240 min.
Pause between alerts per coin: 240 min.
Which market to watch: Spot and futures
Min. Exchange 24h Turnover: 10 M $

Logic: one-minute turnover 30 times the coin's usual level over the last few minutes — a sharp burst of activity. A $10M turnover floor: on a thin pair a normal minute is a few hundred dollars of noise, and a multiplier on it means nothing. One alert per coin in four hours.

Any set is a starting point, not a recommendation. Once applied the thresholds are yours: move them and the screener starts counting the new way immediately.

Common mistakes when setting up the 24h turnover screener

Large percentages in the first scenario. Those percentages are measured against the daily volume. A 500% threshold means the coin traded five times more inside your window than in the whole previous day — which almost never happens.

A multiplier with no liquidity filter. The most common source of alerts about coins you have never seen: a relative threshold has nothing to measure on a thin pair.

A minus sign in a minute scenario. Falling turnover can only be set in the first scenario. The minute scenarios fire when a threshold is exceeded.

Turnover as the only condition. A spike says something is happening, not which way. Direction comes from price.

Turnover screener setup FAQ

Which of the three scenarios should I pick?

It depends on what you want to catch. “Turnover per minute” answers “where is the big money right now” and is set as an amount in millions. “Spike against the average” catches a coin waking up and is set as a multiplier — it works the same on bitcoin and on a thin altcoin. “Turnover change” shows a sustained shift in activity over an hour or more, not a one-off spike.

What does a 15% threshold mean in the first scenario?

Those percentages are measured against the daily volume, which makes the thresholds deceptive. An ordinary hour is roughly 1/24 of the daily volume, about 4%. So +15% in an hour means the hour traded around 4.5 times more than usual. A 500% threshold would mean five daily volumes inside your window — which almost never happens.

What does 0.5 mean in the minute turnover field?

Five hundred thousand dollars. That field and both liquidity floors are measured in millions: 0.5 is $500k and 3 is $3m. Minute turnover is estimated from the difference between the rolling daily turnover of two adjacent minutes, so it is an estimate rather than an exact sum of trades.

What multiplier should I set for a spike?

The value in the mockup is 5, while the ready-made setup uses 30. The gap is deliberate: the multiplier compares one minute against the same coin’s average minute over the last 20 minutes, and a five-fold excess happens often on a live market. Start from the ready-made setup and lower the multiplier if you are getting too few alerts.

Why doesn’t the multiplier work without a liquidity filter?

The multiplier is a relative figure, and on a thin pair it has nothing to measure. If a coin’s ordinary minute is two hundred dollars, a five-fold spike is a thousand: an event by the formula and nothing in substance. The minimum daily turnover cuts such pairs before they ever reach the scenario.

Can I get alerts when turnover falls?

Yes, but only in the first scenario: its percentage field accepts a minus sign. A value of −8 over 4 hours means activity is fading. The minute scenarios do not work that way — they fire when a threshold is exceeded, not when it is missed.

What happens if I run the wash-trade filter in soft mode?

Soft mode drops only spikes with a “wash” verdict and passes suspicious ones through as they are. In that mode the “show suspicious in history” toggle changes nothing: suspicious spikes are not being dropped anyway. It only starts to matter in strict mode.

? Which of the three scenarios should I pick?

How turnover differs from volume, and why the two get confused, is covered in “What trading volume is”. How the screener measures it and what the alert contains is in the screener description, and thresholds for specific jobs are in turnover use cases.

Everything described above is set up in the screener: pick a ready-made setup or your own thresholds, and alerts arrive by push or Telegram.
