What is not available yet

One list of what a script cannot do in this release, what the editor says when you try, and what to write instead. Checked against the engine.

This page collects in one place what members cannot do with scripts in this release. Where a script tries, the engine refuses it with an error, so a script never runs with a meaning it was not written for. Every item below was checked against the engine that runs on the chart.

Things the platform does not offer yet#

What	What happens	What to do instead
Alerts on your own scripts	Creating one is refused: "Alerts on your own scripts are not available." The script itself compiles and runs	Watch the chart, or set a price alert on a level
Sharing a script with another member	There is no way to share; every script is private to your account	Copy the text yourself if you want to keep it elsewhere
Libraries supplied by the platform	Only modules you saved yourself can be imported	Write the module yourself (Lesson 12)
Data of another symbol	Refused: `E-REQ-UNDECLARED` without a `uses` line, `E4001` with one	Read your chart's own symbol (`symbol = symbol.id`)
A panel or a scan of several symbols	Not available	One symbol per chart; use the chart grid to watch several
Showing the log in the editor	`log.info`, `log.warning` and `log.error` are accepted and kept by the engine, but no panel lists them	Draw the value: Lesson 13

Words of the language reserved for a later edition#

These are written into the language now and refused, so that a script written for them cannot run with the wrong meaning. The message says the word is reserved (E9002):

the inputs preset, bind and secret;
the blocks on close and on tick;
the report statement and the bracket order statement.

funding and hedge are not settings of a strategy's header; writing them is E3130.

Forms that are not part of the language#

These are simply not known. Write the form on the right:

Not known	Code	Write instead
An item of a list as `items[i]`	`E3173`	`items.at(i)` (`items[1]` reads the list as it was one bar back)
Selectors on lists such as `.where(...)` and `.count(...)`	`E5140`	a `for` loop over the items
`pips(x)`, `to_ticks(d)`	`E3160`	multiply by `symbol.pip`, divide by `symbol.tick`
A cooldown or an expiry written `3 bars`	`E2002`	the number: `cooldown = 3`
`json(...)` to build an alert message	`E3160`	build the text yourself with `f"..."`
A function without a name (`fn(x) => ...` as a value)	`E2006`	declare a named function with `fn`
`nz(x)`	`E3160`	`x ?? 0`

What works, with limits#

Some things are available but bounded; they are not missing:

Your plan decides how many scripts you can keep: 2 on the free chart plan, up to 100 on MillionChart Pro.
A script can read other timeframes of its own symbol, up to 20 of them (Lesson 10).
The engine bounds work, history, memory and drawings (Lesson 17, Limits and budgets).
