Function catalog

Complete list of built-in functions in @efixdata/exeria-chart. Pass Key to chart.addScript("KEY").

Functions transform series — see Functions overview if this concept is new.

Per-function reference

HIGHEST — Highest

Rolling maximum of the chosen series (default: high). Draws an upper envelope line on the main chart.

chart.addScript("HIGHEST");

LOWEST — Lowest

Rolling minimum (default: low). Lower envelope on the main chart.

chart.addScript("LOWEST");

FIBONACCI — Fibonacci

Rolling Fibonacci retracement/extension levels from rolling high/low windows. Overlay bands.

chart.addScript("FIBONACCI");

DISPLACE — Displace

Shifts a source series by N bars and adds a numeric offset. Wire DSERIES to any output (e.g. EMA).

chart.addScript("DISPLACE"); // set DSERIES in UI after EMA exists

IGLUE — Indicator Glue

Element-wise math between two series: Add, Subtract, Multiply, Divide, Power.

chart.addScript("IGLUE"); // pick FIRST + SECOND series in settings

IMOD — Indicator Modifier

Same operation list as IGLUE, but second operand is a constant modifier.

IF — IF

Compares VAL_A and VAL_B (number or series). Outputs VAL_X if A > B, VAL_Y if equal, VAL_Z if A < B. Opens in a new panel by default.

SUM — Sum

Adds up to ten conditional inputs (constants or series). Skips unset slots.

AVERAGE — Average

Averages up to ten conditional inputs; ignores missing values.

1x — 1/x

Reciprocal 1 / x for each bar of the input series. New panel.

Wiring reminder

Series inputs use seriesId:field strings. Clone definitions before mutating:

const fn = structuredClone(chart.getScripts().DISPLACE);
fn.inputs.DSERIES.value = emaReference;
chart.addScript("DISPLACE", fn);
