Output

Kind: module

Namespace: output

Outputs values without visualization. For most use cases, use spline which provides styling and chart integration. For per-bar background fill, use bgColor.

Each output maintains one value per bar. A new value is added when a new bar starts and replaced when the current bar updates.

output()

Kind: func

Outputs a named value.

Syntax

output(name, value) → void

Arguments

Name	Type	Description
name	string	Unique identifier for the output
value	number, series	Value to output for the current bar

Returns

void

Caveats

• Must be called inside onTick(), not in the init section
• Must be at the top level of onTick(), not inside conditionals or loops. This ensures the call count and order remain constant across ticks

Pitfall

function onTick() {
    if (bar.isConfirmed()) {
        output("close", close);  // ❌ inside conditional
    }
}

Example

function onTick() {
    const sma = ta.sma(close, 20);
    const ema = ta.ema(close, 20);

    output("sma", sma);
    output("ema", ema);
    output("diff", sma - ema);
    output("close", close);
}
