Range Bar range guidance

Can anyone offer any rules-of-thumb (or similar words of wisdom) for setting Range Bar range for a given instrument?

Are there any rules say like “set range to 2 x ATR(14, 1 min)”, etc ... ? Or something similar?

My focus is intraday trades.

Thanks, and pardon my ignorance.

 

1) Use something that you, yourself, feel comfortable with.
2) Use something related to what you're willing to risk in trading a specific instrument.
3) Use something related to the average daily expected range for the instrument.

 

Many thanks.
