Indicators overview

Indicators are the classic chart studies — moving averages, bands, oscillators, volume tools. Exeria ships 97 built-in indicators.

Add them from the toolbar or with one line of code.

Loading chart…

EMA overlay + RSI panel — the most common first combo.

Add an indicator in code

import { createChart } from "@efixdata/exeria-chart";

const chart = createChart({ container, instrument });
chart.init();
await chart.setMainSeriesData(candles, interval);

chart.addScript("EMA");
chart.addScript("RSI");

The string key ("EMA", "RSI") must match the catalog.

Tutorial: Add an indicator.

Add an indicator in ChartUI

1. Toolbar → Indicators.
2. Tab Indicator.
3. Search or browse → select one.
4. Set Parameters (periods, series inputs).
5. Choose Panel — Series and panels.
6. OK.

Choose the input series

Most indicators default to close (c). In settings, change Price CLOSE (or equivalent) to:

• high, low, open, volume
• another symbol’s field (multi-instrument)
• another indicator’s output (advanced pipelines)

Example: run RSI on high instead of close for a stricter overbought read.

Guide: Series and panels.

Overlay vs new panel

Default	Meaning	Examples
Overlay	Draws on the candle panel	EMA, SMA, BBAND, ICHIMOKU
New panel	Opens a strip below price	RSI, MACD, ATR, OBV, CCI

Override anytime with the Panel dropdown before confirming.

Inspect before adding

const rsi = chart.getScripts().RSI;

console.log(rsi.title);      // localized display name
console.log(rsi.newPane);    // default panel behavior
console.log(rsi.inputs);     // PERIOD, CLOSE, baselines…
console.log(rsi.outputs);    // output field names for wiring

Output field names (e.g. EMA, RSI, MACDLine) become available in series dropdowns for functions and strategies.

Customize defaults

addScript("EMA") uses baked-in defaults (PERIODS = 14, close series). To change them:

const ema = structuredClone(chart.getScripts().EMA);
ema.inputs.PERIODS.value = 21;
chart.addScript("EMA", ema);

Same pattern for any indicator. Wiring to other scripts: Programmatic wiring.

Licensed packs

Some indicators (DiNapoli family) require a subscription pack in licensed deployments. Keys still appear in getScripts(); your license gate may hide them in UI.

Good first indicators

Key	Why start here
EMA	Simple overlay trend line
BBAND	Volatility bands on price
RSI	Separate-panel oscillator
MACD	Multi-line momentum panel
ATR	Volatility in its own pane
