What is A/D Line (Accumulation/Distribution)?
A cumulative volume line like OBV, but weighting each day by where price closed within its range β a day closing near its high counts as accumulation even if it finished slightly red.
Formula
A/D = Prior A/D + Volume Γ ((Close β Low) β (High β Close)) Γ· (High β Low)
How to Interpret
Same grammar as OBV β trend and divergence against price. Because it reads intraday close position, it sometimes catches quiet accumulation OBV misses.
Typical Ranges
Ignores gaps entirely (a limitation OBV doesn't have) β an asset gapping up daily but closing mid-range can show a falling A/D line while price soars.
