Global functions

31 functions. Each has a page of its own.

Function	Summary
`alert`	Raises an alert from inside your own logic, with a message you build.
`alertcondition`	Declares a condition the platform can offer to the reader. It raises nothing by itself.
`barcolor`	Recolours the chart’s own price bars. It draws no value of its own.
`bgcolor`	Shades the pane’s background. Like `barcolor` it adds no value to the chart.
`bool`	A true-or-false value. The two constants `true` and `false` are the literals for it.
`color`	A colour. You can write one directly as a hex literal — six digits for the colour, eight to carry alpha as well.
`dayofmonth`	The day of the month of the bar being evaluated.
`dayofweek`	The day of the week of the bar being evaluated.
`fill`	Shades the band between two plots, or between two horizontal lines. It has two forms and no mixed one, so you cannot fill between a plot and a level, and like the other output calls it must sit at the top level.
`fixnan`	Takes a series and hands back a series of the same type, with `na` values dealt with.
`float`	A number with a fractional part, written `1.5`. It has no fields.
`hline`	The value `hline` gives back once it has drawn a horizontal level.
`hour`	The hour of the bar being evaluated.
`indicator`	Declares the script and names it. Put it first.
`input`	Eleven functions, one per kind of setting the reader can change from the chart: bool, colour, float, int, price, session, source, string, text area, time and timeframe.
`int`	A whole number. One of the five data types the grammar names directly.
`minute`	The minute of the bar being evaluated.
`month`	The month of the bar being evaluated.
`na`	Tests whether a value is absent. It takes any type and gives back a bool.
`nz`	Takes a value and an alternative of the same type, and stands in for the value where it is absent.
`plot`	The value `plot` gives back once it has drawn a series.
`plotarrow`	Draws an arrow on each bar, sized from a number you supply.
`plotbar`	Draws bars from the same four required series that `plotcandle` takes.
`plotcandle`	Draws candles from four series of your own rather than from the chart’s bars.
`plotchar`	The same marker as `plotshape`, with one character in place of a shape from the fixed set.
`plotshape`	Marks the bars on which a condition holds, using a shape from a fixed set.
`second`	The second of the bar being evaluated.
`string`	A piece of text, written between double quotes: `"length"`.
`timestamp`	Assembles a time from its parts - the other direction from the eight functions that take a time apart.
`weekofyear`	The week of the year of a time you supply.
`year`	The year of the bar being evaluated.
