str.pos

Reports the position at which one string sits inside another. The result is an int. This edition does not state what that int is counted from, nor what it reads when there is no match, so do not rely on either.

str.pos(const string source, const string str) → const int

str.pos(input string source, input string str) → input int

str.pos(series string source, series string str) → series int

str.pos(simple string source, simple string str) → simple int

Returns const int or input int or series int or simple int — A series int: the position of needle, counted from zero, or -1 where it does not occur. The position is a byte offset, so it is not interchangeable with the character positions str.substring takes once the text goes outside ASCII.

indicator("Position of USD in a string")
plot(str.pos("EURUSD", "USD"))
