float

Adds a floating-point number field to your indicator’s Inputs panel. Useful for decimal values like thresholds, multipliers, percentages, or coefficients. Like int(), you can define minimum, maximum, and step values to constrain what the user can enter.

Syntax

input.float(title, value, id?, min?, max?, step?, tooltip?, group?, inline?)

Parameters

• title string — Label shown in the Inputs panel.

• value number — Default decimal value.

• id string (optional) — Unique key for referencing this input. Auto-generated from title if omitted (lowercased, no spaces).

• min number (optional) — Minimum allowed value.

• max number (optional) — Maximum allowed value.

• step number (optional) — Increment between values (e.g., 0.1 → values like 0.1, 0.2, 0.3).

• tooltip string (optional) — Hover text that explains the parameter.

• group string (optional) — Organizes this input under a collapsible section.

• inline string (optional) — Aligns multiple inputs in one row if they share the same inline key.

Return Value

{ id: string } — The assigned id, either provided or auto-generated.

Example

//@version=1

// This is the setup function.
// Here you can define the input parameters for the indicator.
init = () => {
  // Example: Add a float input for multiplier
  input.float(
    'ATR Multiplier',
    1.5,
    undefined,         // auto id: "atrmultiplier"
    0.1,               // min
    10,                // max
    0.1,               // step
    'Factor applied to ATR for stop calculation',
    'Risk Management',
    'risk-row'
  );
}

onTick = (length, _moment, _, ta, inputs) => {

};

Result

Tips

• Use step values like 0.1 or 0.01 to make fine-tuning easy for users.

• Keep default values practical (e.g., 1.5 for ATR multipliers is a common starting point).

Warning

Without min and max, users can enter extreme values that may break your logic. Always validate in your code if ranges matter.

Good Practice

• Place float inputs in groups like Risk Management, Thresholds, or Sensitivity so users instantly understand context.

• Pair float parameters with related integer ones using the same inline key to create cleaner forms (e.g., ATR Length + Multiplier on the same row).
