What indicators and conditions are available in the TA Scanner?

The TA Scanner lets you build conditions from over 100 indicators across several categories. This article lists every indicator available in the rule builder and expression editor, what it measures, and how to use it in a condition.

OHLC indicators

The Open, High, Low and Close indicators represent the OHLC values of the most recently completed candle at the resolution(s) selected in your global filters. For example, if you select the 15m resolution, close is the closing price of the last completed 15-minute candle. If you select multiple resolutions, each market is evaluated at each resolution independently.

Price indicators can be compared to other price-scale indicators (moving averages, Bollinger Bands) or to a fixed numeric value.

Volume (volume): trading volume for the candle in the base currency.
24h Change % (change_24h): the 24-hour price change expressed as a percentage. Use this to filter for markets that have moved significantly in either direction, for example change_24h > 5 for markets up more than 5% in the last 24 hours.

Moving averages

Indicator	ID examples	Periods available
SMA (Simple Moving Average)	`sma5`, `sma20`, `sma200`	5, 10, 20, 30, 50, 100, 200
EMA (Exponential Moving Average)	`ema9`, `ema26`, `ema200`	9, 12, 13, 26, 50, 100, 200
WMA High (Weighted Moving Average of High)	`wma5_high`, `wma10_high`	5, 10
WMA Low (Weighted Moving Average of Low)	`wma5_low`, `wma10_low`	5, 10

All moving averages use the price unit, meaning they can be compared to each other, to OHLC values, and to Bollinger Bands.

The WMA High variants are useful as dynamic resistance levels, while WMA Low variants work as dynamic support levels.

Oscillators

Oscillators measure momentum and have defined ranges.

Indicator	ID	Range	Oversold	Overbought
RSI	`rsi9`, `rsi14`, `rsi25`	0 to 100	< 30	> 70
Stochastic %K / %D	`stochk`, `stochd`	0 to 100	< 20	> 80
StochRSI %K / %D	`stochrsi_k`, `stochrsi_d`	0 to 100	< 20	> 80
CCI (20)	`cci20`	No fixed range	< -100	> 100
Williams %R (14)	`williams_r`	-100 to 0	< -80	> -20
MFI (14)	`mfi14`	0 to 100	< 20	> 80
Momentum (10)	`mom10`	No fixed range	n/a	n/a

RSI is available in three periods (9, 14, 25). Stochastic uses a 14,3,3 configuration. MFI is similar to RSI but incorporates volume data. Momentum uses the price unit, so it can be compared against other price-scale indicators.

MACD

Indicator	ID
MACD Line	`macd_line`
MACD Signal	`macd_signal`
MACD Histogram	`macd_hist`

The MACD Line crossing above the Signal Line is a common bullish setup; crossing below is bearish. The Histogram shows the distance between the two lines, so a histogram at zero means the lines are crossing.

Bollinger Bands

Standard Bollinger Bands use a 20-period SMA with 2 standard deviations.

Indicator	ID
BB Upper	`bb20_upper`
BB Middle	`bb20_middle`
BB Lower	`bb20_lower`
BB Width %	`bb20_width_pct`

The Upper, Middle and Lower bands use the price unit and can be compared to OHLC values and moving averages. BB Width % uses the percent unit, so it can only be compared to other percent-based indicators (like Drop/Rise) or a numeric value. Low BB Width % values indicate a volatility squeeze; high values indicate expansion.

Trend indicators

Indicator	ID	What it measures
ADX (14)	`adx14`	Trend strength (not direction). Below 20 suggests a ranging market; above 25 indicates a strong trend.
ATR (14)	`atr14`	Market volatility, averaged over 14 periods. Rising ATR means increasing volatility; falling ATR means a quieting market.
Std Dev (20)	`stddev20`	How far price has deviated from its 20-period mean. High readings mean wide dispersion; low readings mean prices are tightly clustered.

Ratings

Composite trend ratings derived from moving average and oscillator signals. These provide a high-level view of market sentiment without needing to configure individual indicators.

Indicator	ID	Range	Description
MA Score	`ma_score`	-14 to 14	Net MA signal count: +1 per bullish signal, -1 per bearish, across 14 MAs (7 SMA + 7 EMA).
Oscillator Score	`osc_score`	-14 to 14	Net oscillator signal count: +1 per bullish, -1 per bearish, across 14 oscillators.
Total Score	`total_score`	-28 to 28	Composite score (MA Score + Oscillator Score).
Trend	`trend`	-2 to 2	Strong Sell (-2), Sell (-1), Neutral (0), Buy (1), Strong Buy (2). In the visual editor this shows as a dropdown selector instead of a numeric input.
MA Trend	`ma_trend`	-2 to 2	MA-only trend rating, same scale as Trend.
Oscillator Trend	`osc_trend`	-2 to 2	Oscillator-only trend rating, same scale as Trend.

To scan for markets where both MAs and oscillators agree on a strong bullish outlook: trend == 2. To find markets where MAs are strongly bullish but oscillators haven’t confirmed yet: ma_trend == 2 AND osc_trend < 1.

Quick Scanner indicators (Drop, Rise, Fat Finger)

These indicators carry over from the original Quick Scanner and measure sudden, sharp price movements within a rolling time window.

Drop (drop_5m, drop_10m, drop_15m, drop_30m): percentage drop from the N-bar high, only when actively dropping. Use with > to detect drops larger than a threshold, for example drop_15m > 3 means “price dropped more than 3% from its 15-bar high”.

Rise (rise_5m, rise_10m, rise_15m, rise_30m): percentage rise from the N-bar low, only when actively rising. Use with > to detect rises larger than a threshold, for example rise_15m > 3 means “price rose more than 3% from its 15-bar low”.

Fat Finger Buy/Sell (fatfinger_buy_5m, fatfinger_sell_5m, etc.): detects anomalous price spikes caused by unusually large or erroneous orders. A Fat Finger Buy is the percentage the ask price is below the N-bar high (potential buy opportunity from a panic sell), while Fat Finger Sell is the percentage the bid price is above the N-bar low. The value represents the percentage magnitude of the deviation.

Drop, Rise and Fat Finger all use the percent unit, so they can be compared to each other, to BB Width %, or to a numeric value.

Comparing indicators in conditions

Not all indicators can be compared to each other. The scanner groups indicators by unit:

Price unit: OHLC, all moving averages (SMA, EMA, WMA), Bollinger Bands (Upper/Middle/Lower), Momentum, ATR. These can all be compared to each other.
Percent unit: 24h Change %, BB Width %, Drop, Rise, Fat Finger. These can be compared to each other.
Own-scale indicators: RSI, Stochastic, StochRSI, CCI, Williams %R, MFI, ADX, Std Dev, MACD, Ratings. These are typically compared to a numeric value rather than to each other.

If you try to compare two indicators with incompatible units (for example RSI against an EMA), the expression editor flags it as an error.
