#Syntax

Code	Severity	Message
`CS1001`	error	The first line must be //@chartscript 1
`CS1002`	error	ChartScript version `version` is not known to this compiler (newest: `max`).
`CS1003`	error	The script must start with indicator(...) or library(...) after the header.

`CS1022`	error	Unknown escape sequence `esc`.
`CS1023`	error	This string is longer than `max` characters.
`CS1024`	error	A color literal is #RRGGBB or #RRGGBBAA.

`CS1031`	error	`open` is not closed.
`CS1032`	error	Expected an expression.
`CS1033`	error	Expected the end of the statement.
`CS1034`	error	Expected a block { … }.
`CS1035`	error	Positional arguments must come before named arguments.
`CS1036`	error	Only a variable or a field can be assigned to.
`CS1037`	error	Expected => or a block { … } after the parameter list.
`CS1038`	error	Too many errors; the rest of the script was not checked.
`CS1040`	error	The script is too large: a script can hold up to `max` KB of code.
`CS1041`	error	Expressions or blocks are nested too deeply (more than `max` levels).
`CS1050`	error	`name` is not used in ChartScript: use `hint`.
`CS1051`	error	return can only be the last statement of a function (or of each branch of a final if / switch).

#Names, types and qualifiers

Code	Severity	Message
`CS2001`	error	`name` is not defined.
`CS2002`	error	`name` is already declared in this block (line `line`).
`CS2003`	error	`name` is a built-in namespace and cannot be used as a name.
`CS2004`	error	`name` has no member `member`.
`CS2005`	error	`name` takes `expected` arguments, not `got`.
`CS2006`	error	`name` has no parameter named `param`.
`CS2007`	error	The argument `param` is given twice.
`CS2008`	error	Expected `expected` but got `got`.
`CS2009`	error	`name` is not a function.
`CS2010`	error	`name` is not available yet (coming in a later version of ChartScript).
`CS2011`	error	`name` is not supported in ChartScript.
`CS2012`	error	This returns `got` values but `expected` names are given.
`CS2013`	error	This call returns no value.
`CS2014`	error	`value` is not one of the allowed values: `options`.
`CS2015`	hint	`name` works here as `hint`, the ChartScript keyword with the same meaning.
`CS2101`	error	The argument `param` of `name` must be the same on every bar (`needed`), but this value is `got`.
`CS2102`	hint	The length changes from bar to bar, so `name` keeps max_bars_back (`n`) values.
`CS2103`	error	The argument `param` of `name` must be a constant.
`CS2104`	error	The argument `param` of `name` must be a constant or an input.
`CS2201`	error	Give `name` a type, for example: `example`
`CS2203`	error	Comparing with na is always false; use na(`name`) instead.
`CS2204`	error	A condition cannot be na; write: `example`
`CS2301`	warning	`name` is the same object on every bar, so `name`[n] returns the same object.
`CS2302`	error	A history offset must be a whole number of 0 or more.
`CS2401`	error	`name` is not declared; declare it with `decl` before assigning to it.
`CS2402`	warning	This declares a new `name` that hides the one from line `line`; did you mean to change it with `op` ?
`CS2403`	error	A function cannot change the global `name` unless it is declared with `kw`.
`CS2404`	error	`name` cannot be changed (it is `what`).
`CS2405`	error	`name` is `expected`; it cannot be given a `got` value.
`CS2501`	error	`name` calls itself (through `path`); recursion is not allowed.
`CS2502`	error	Functions cannot be declared inside other functions.
`CS2503`	warning	`name` inside a condition only updates on the bars where this line runs. Move it out of the condition for the usual result.
`CS2504`	warning	`name` inside a loop keeps one value per bar: only its last call on each bar counts.
`CS2506`	hint	`text` divides two whole numbers: the result keeps its fraction. Write int(`text`) if a whole number was meant.
`CS2601`	error	A field cannot be named `name`.
`CS2602`	error	A type can have at most `max` fields.
`CS2603`	error	A method needs the type of the object it works on: `example`.
`CS2604`	error	A field default must be a constant (field `name`).
`CS2701`	error	A condition must be a bool, but this is `got`.
`CS2702`	error	A loop over the items of a list needs an array.
`CS2703`	error	`word` can only be used inside a loop.
`CS2710`	error	`name` can only be used at the top level of the script.
`CS2711`	error	The argument `param` of `name` must be a constant.
`CS2712`	error	This is not a settings condition: use inputs, constants, timeframe.in_seconds(), timeframe.period and market.kind with `logic`, comparisons, + - * / and ?: (`detail`).
`CS2713`	error	`name` has no style property `prop`.
`CS2714`	error	A check must be a bool, but this is `got`.
`CS2715`	error	The preset `preset` names `name`, which is not an input of this script.
`CS2716`	error	The preset `preset` gives `name` the value `value`, which the input does not allow.
`CS2717`	error	This migration conflicts with another one for `name` (version `since`).
`CS2718`	warning	The id of `what` changed from `was` to `now` since the previous version; saved styles for it will be lost. Give it the id "`was`" again to keep them.
`CS2719`	hint	No `lang` translation for "`text`".
`CS2720`	error	The id `id` is used twice (`what`).
`CS2721`	error	A script can have at most `max` `what`.
`CS2722`	error	The style property `prop` does not apply to `kind`.
`CS2723`	error	The unit `unit` does not apply to this input.
`CS2724`	error	The lower default `lo` is above the upper default `hi`.
`CS2725`	error	look cannot be used on `kind`.
`CS2726`	error	`name` is not an input of this script.

#Limits, outputs, requests and alerts

Code	Severity	Message
`CS3001`	error	A script can have at most `max` plots.
`CS3002`	error	A script can have at most `max` inputs.
`CS3003`	error	A script can have at most `max` alert conditions.
`CS3004`	error	This script uses `n` other timeframes or markets; your plan allows `max`.
`CS3005`	error	max_bars_back must be between `min` and `max`.
`CS3007`	error	`name` can only be used at the top level of the script, not inside a condition, loop or function.
`CS3101`	error	request.developing needs a timeframe that is a whole multiple of the chart's, on the same market.
`CS3102`	error	A lower timeframe than the chart is only available through request.lower_tf.
`CS3103`	warning	There are no "`tf`" bars: the seconds timeframes are 1S, 5S, 10S, 15S, 30S and 45S. This request gives na.
`CS3104`	warning	The market `market` is not known; its values will be na.
`CS3110`	error	`leaf` is not known when the `tf` bar opens; use `leaf`[1] or `atClose`.
`CS3120`	error	Plots, inputs, drawings and alerts cannot be used inside a request expression.
`CS3121`	error	A request cannot sit inside another request’s expression.
`CS3122`	warning	`name` changes on the chart bars (`how`), so a request cannot recompute it on the requested bars: there it is na (`kw`) or the chart’s current value. Compute it in a function called inside the request.
`CS3123`	warning	`name` belongs to the code around this request; the request expression runs on other bars and reads it as na. Pass a market / timeframe instead, or compute the value inside the request.
`CS3124`	warning	`name` is ChartDeck data of the chart’s own market: inside a request expression it reads na. Read it outside the request (its value is already aligned to the chart’s bars).
`CS3190`	warning	`name` returns na in this version: other timeframes and markets arrive in a later version.
`CS3201`	error	alert.on can only be used at the top level of the script.

#Imports and libraries

Code	Severity	Message
`CS4001`	error	The library `path` was not found.
`CS4002`	error	Libraries import each other in a circle: `path`.
`CS4003`	error	An exported function cannot use input.*.
`CS4004`	error	The library `path` has errors (line `line`: `detail`).
`CS4005`	error	export can only be used in a library.
`CS4006`	error	`name` is not exported by `path`.
`CS4007`	error	`path` is not a library.
`CS4010`	error	Libraries and imports are not available yet (coming in a later version of ChartScript).

#Runtime

Code	Severity	Message
`CS5001`	error	`message`
`CS5101`	error	Index `index` is out of range (size `size`).
`CS5102`	error	`name` is na.
`CS5103`	error	A collection can hold at most `max` elements.
`CS5104`	error	A string can be at most `max` characters.
`CS5105`	error	A map key cannot be na.
`CS5106`	error	The matrix sizes do not fit (`detail`).
`CS5107`	error	`name` needs a square symmetric matrix in this version.
`CS5120`	error	A script's heatmaps can hold at most `max` cells: clear old columns (heatmap.clear) or add fewer rows.
`CS5121`	error	A heatmap column can have at most `max` rows (this one has `got`).
`CS5201`	error	A history offset cannot be negative or na (got `offset`).
`CS5202`	error	`name`[...] reached `offset` bars back; raise max_bars_back to `suggest` in indicator().
`CS5301`	error	A loop ran more than `max` times on one bar.
`CS5302`	warning	The array is changed inside the loop that goes through it; the loop goes on with its new size. An index loop says that more clearly.
`CS5303`	error	Loops ran more than `max` times in total on one bar.
`CS5401`	error	Stopped: the script took too long (`ms` ms; the limit is `max` ms).
`CS5402`	error	Stopped: one live update took too long (`ms` ms; the limit is `max` ms).
`CS5403`	error	Stopped: the script used more memory than allowed.
`CS5404`	error	Stopped: the script stopped answering and was shut down.
`CS5501`	error	Internal runtime error: `detail`
