BBTK2 - AD%
Accumulation-Distribution % (AD%) is the closed form of
Accumulation-Distribution(AD). AD% is calculated by taking the
n-period sum of AD and dividing by the n-period sum of volume;
the result is a normalized AD that is now comparable from issue
to issue. 20 is the default period.
This indicator is included in the Bollinger Band Toolkit Add-on: https://www.metastock.com/products/thirdparty/?3pc-add-bbtk2
Can you please share a calculation formula in metastock formate with default 20 period plz//?
