One full cycle, bar by bar. Price on top, the flow-depth middle bar below it, and the two side bars underneath that. The point of the walkthrough is the level the flow leaves behind when a regime turns, and what it takes to legitimise a price break afterwards.
Illustrative sequence, built to make the behaviour legible — not market data.
Bullish and bearish flow do not hand off cleanly. Each turn leaves a minor high or minor low in the flow itself, formed some variable number of bars before the regime actually changes.
When the regime turns lower, the most recent flow high is what stands. Flow has to push beyond that level before a bullish break of price is accommodated. When the regime turns higher, the most recent flow low stands, and a bearish break needs flow beyond it.
The level persists until it is exceeded. It is not a record of the last regime — it is the admission price for the next break.
The same sequence, with the two side bars carrying the reading. Notice the character changes even while the middle bar keeps its sign — the move stops being counter weakness and becomes base strength well before the barrier breaks.
