Ideas

The screener ranks Binance futures by the product of average trade size, price and daily volatility, and shows how this value changed over 15 minutes. The model does not tell the price direction.

What it is

Ideas looks for coins where both the average trade size and the volatility have grown. The model is computed on the server from 1-minute candles of Binance USDT perpetual futures, for all trading coins. The value is recalculated every second and saved to history once a minute. The current, still open candle is included in the calculation.

Ideas is available in two forms:

• the Ideas widget: a table of all coins with the model value and its change over 15 minutes;
• the [SFM] Ideas indicator on the chart ([SF] Ideas in the chart legend): a line with the model value below the chart.

The widget is part of the Max plan because it shows the whole market at once. The chart indicator is available from Pro because it shows a single coin. The widget opens from the "Screeners → Microstructure → Ideas" menu.

Formula

For each 1-minute candle the model takes the average trade size: volume in coins divided by the number of trades. A candle with no trades gives zero.

$$w = \sum_{220} \frac{Volume}{Trades} × Close × StDev_{1440}(Close)$$

where:

• $\sum_{220}$ is the sum of average trade sizes over the last 220 minutes;
• $Close$ is the close price of the current candle;
• $StDev_{1440}(Close)$ is the standard deviation of the close price over the last 1440 minutes (one day), in price units.

Change over 15 minutes, in percent:

$$Chg\% = \frac{w}{w_{-15}} × 100 - 100$$

where $w_{-15}$ is the model value 15 one-minute candles ago.

Widget

Column	What it shows
Symbol	Coin
Value	Model value $w$
Chg%	Change of $w$ over 15 minutes. Green is growth, red is decline

By default the table is sorted by Chg% in descending order. When a coin changes in the top five rows, the row flashes for a second: green when sorted in descending order, red when sorted in ascending order.

The filter window has two fields: Value and Change %. A positive number keeps rows with a value not lower than the one entered, a negative number keeps rows with a value not higher than it. For example, Change % = 20 shows coins where $w$ grew by 20% or more over 15 minutes. The global filters of the control panel and the blacklist also apply to the table.

Indicator

The [SFM] Ideas indicator draws the value $w$ as a white step line in a separate pane below the chart. It has one setting, Symbol: by default it uses the chart coin, and you can set another one.

How to read it

• Compare coins by Chg%, not by Value. Value depends on the price level: both $Close$ and the standard deviation are measured in price units. So when sorted by Value, expensive coins are almost always at the top, and this does not mean anything unusual is happening in them. Chg% is a relative value and can be compared across coins, which is why the table is sorted by it by default.
• A high Chg% means that at least one of the three factors grew over 15 minutes: the average trade size over the last 220 minutes, the price, or the daily volatility. The 220-minute sum and the daily deviation change slowly, so a sharp jump in Chg% usually means large trades or a sharp price move in the last minutes.
• The model gives no direction. Large trades and rising volatility happen both on the way up and on the way down. Look for the side of the move in other models: Volume delta, Big Trades, Power trades.

Limitations

• Binance USDT perpetual futures only.
• Value is not comparable across coins, see above.
• The value from the current candle changes until the candle closes.
• The calculation needs at least 1,455 one-minute candles of history, so a newly listed coin has no value for its first day.
• There is no public backtest of the model yet. We do not claim that a rise in Chg% predicts a price move.
