❓Bar Sizing ❓

This goes out to Sharp-Shooter or anyone else who may have a specific set of criteria for selection.

How do you determine which bar (time, range, renko, etc.) and what size of bar to use for your instruments?

I ask because I trade very basic bars. I'm currently only taking trades off a 1 min chart. In the past I've used renko, range, and tick bars, and tried to based the size off how quickly I could analyze what I could interpret from the information. I have never thought I had a good grasp of how to appropriately select the bar. That's why I've come to only watch 5, 30, and 240 for the "big picture" and select setups from the 1 min.
