Quick question to see if it's possible to have an indicator that is already running take a global variable as an input and then recalculate all bars? For example: feed Exponential Moving Average indicator different Length parameters via global variable and have the EMA replot using the new length.

Right now it takes from 7-10 mouse clicks/key strokes to change an indicator's input value and then restart it so it re-plots across all bars. If this can be done I'll build a simple code that presents the input values as on-screen text objects that can be clicked to change the global variable which will, in turn, feed to the indicator.

Thoughts? Answers?

Hello, PD Quig!

Unfortunately it’s impossible to change inputs dynamically neither from a PowerLanguage code, nor via any other means.

Not what I wanted to hear, but thanks so much for the rapid reply, Anna.
