input

A number the trader can change in the script inputs UI.

name = input 9 as "Fast EMA"

Default value is the number after input. The quoted title is what the UI shows. Use the variable in functions: ema(close, fastLen). The old word ask means the same thing and still runs; new scripts should use input (ask is easy to confuse with bid/ask price).
