This is an example script for checking how far the current bar has progressed towards it's completed state. This works for any time frame, eliminating extra logic calls and conversions for each timeframe.period. It is not intended to be a standalone indicator, but rather as a resource for additional logic triggers on the real time bar of a pine script.
The main caveat is that pine script calculations occur on a per-tick basis. This means that the completion percentage can exceed the percentage threshold before any logic is executed. This happens when the next tick occurs after the threshold. The relevance then will depend on the activity of the underlying asset. Longer time frames on low activity assets will likely be more relevant than their shorter time frame counterparts.
