CS1003

error The script must start with indicator(...) or library(...) after the header.

#What it means

After the header, a script declares what it is with indicator(...) or library(...). The compiler did not find that declaration where it belongs.

#Typical cause

• The declaration is missing altogether.
• Other statements come before it. Only import lines and simple variable declarations may come before the declaration.

#How to fix it

Add indicator("Title") (or library("Name")) right after the header, before plots, calls and other statements.

#Example

//@chartscript 1
plot(close)

Fixed

//@chartscript 1
indicator("Close line", { overlay: true })
plot(close)

#Related

• CS1001 — The first line must be //@chartscript 1
• CS1004 — Only one indicator(...) or library(...) declaration is allowed.
