Standard calculations for calculating Money Flow multiplier and Accumulation/Distribution.

FYI, calculation differs from OBV because OBV looks at the days close compared to prior close whereas AD looks at the close with respect to the daily high-low range

Accumulation/Distribution is a volume-based indicator which cumulatively measures trading volume scaled using a money flow multiplier to reflect daily buying/selling pressure over time.

Money flow multiplier is positive when buying pressure > selling pressure (close is nearer to the top of the high-low range). High positive multipliers multiplied by high volume shows strong buying pressure leading to a rising AD line

Money Flow multiplier is negative when selling pressure > buying pressure (close is nearer to the bottom of the high-low range). Low negative values multiplied by high volume shows strong selling pressure leading to a fallingAD line

The accumulation confirms the trend if it is alongside rising prices. Distribution alongside a uptrend in price suggests a weakening and possible upcoming reversal. Conversely, falling prices with increasing accumulation signals increasing bearish selling pressure and the distribution indicates that the bearishness is weakening and a reversal could be coming
