On every chart

Everything in this module has been drawn on the 4 hour chart. Nothing about it depends on that choice.

Any timeframe produces them

A trend ends on the daily chart, and a block forms. A trend ends on the 5 minute chart, and a block forms there too.

The events that make one are the same at every scale. A swing point, a sweep of it, then a close past the last swing in the other direction.

A block forms wherever a trend ends, on whatever chart you are watching.

Which is why the method travels

This is the reason the whole approach works the same on any chart you open.
