Blocks

Blocks marks the imbalances price leaves behind when it moves too fast to trade fairly - the gaps that form when one side simply is not there.

What it reads

Price moves because one side runs out of participants.
when the middle candle moves far enough that the wick of the first and the wick of the third do not overlap, the space between them is the zone.
Where is a zone relative to price, above or below, and how far.
How long it has been there.
And whether it has already been resolved.

Blocks draws that band.
A zone stretches to the right for as long as it goes untouched, so its width is its age.
When price finally trades back through one, it turns grey and stays on the chart instead of disappearing.
untouched red imbalance zones above price, resolved grey bands, and a green zone below price

Width is age. A zone starts where the imbalance formed and extends to the right for as long as it goes untouched.
Grey means resolved, not deleted. When price finally trades back through a zone, it turns grey and stays.
Colour is direction of formation, not direction of expectation.
That is the complete list. Everything else on your chart is a different question and needs a different layer.

It will never tell you that a gap gets filled. Plenty never are - four zones on the chart above have been untouched for six months.
Blocks marks where the market left something behind and stops there. What happens next is not a question an indicator gets to answer.
Treating an unfilled zone as a target.
Treating a fill as a signal. Price trading back through a zone is an event, not an instruction.
Using it alone. Blocks describes one narrow property of price behaviour and is silent on everything else.
