Built-In Methods Reference

This page covers the non-TA built-ins that are available to scripts. Use it with:

• Strategy API for strategy.*
• TA Library Reference for ta.*

Built-In Series

These are available in every script:

• open
• high
• low
• close
• volume
• time

Each one is a series and supports .get(offset).

Basket Surface

Built-in	Purpose
symbols(items)	Declares a fixed multi-symbol basket
symbol.open[index]	Open series for basket member
symbol.high[index]	High series for basket member
symbol.low[index]	Low series for basket member
symbol.close[index]	Close series for basket member
symbol.volume[index]	Volume series for basket member

Global Functions

Method	Purpose
script(config)	Declares script type and platform settings
series(initialValue?)	Creates a tracked series for crossover and historical logic
plot(value, options?)	Draws values on the chart

input.*

Method	Purpose
input.integer(name, defaultValue, options?)	Integer input
input.float(name, defaultValue, options?)	Float input
input.bool(name, defaultValue)	Boolean input
input.string(name, defaultValue, options?)	String input
input.source(name, defaultValue)	Price source input
input.color(name, defaultValue)	Color input

math.*

Method	Purpose
math.na()	Returns NaN
math.nz(value, replacement?)	Replaces NaN
math.abs(value)	Absolute value
math.sign(value)	Sign of value
math.round(value)	Round to nearest integer
math.floor(value)	Round down
math.ceil(value)	Round up
math.sqrt(value)	Square root
math.pow(base, exponent)	Power
math.log(value)	Natural logarithm
math.exp(value)	Exponential
math.max(...values)	Maximum
math.min(...values)	Minimum
math.avg(...values)	Average
math.sum(...values)	Sum

plot(...) Options

Option	Purpose
type	Plot type such as line, histogram, area, bar, point, or fill
color	Hex or named color
linewidth	Stroke width
linestyle	Solid, dotted, or dashed
offset	Bar offset
transparency	Visibility control

console.*

Method	Purpose
console.log(...)	Standard logging
console.info(...)	Informational logging
console.warn(...)	Warning logging
console.error(...)	Error logging

Practical Notes

• use series(...) when you need crossover helpers on a derived value
• use input.source(...) when users should choose the price source
• use symbols([...]) only for basket strategies
• use math.* for plain numeric operations and ta.* for indicator logic
