Hello,
In fact this is not a bug.
A/D line is based on cumulative sum.
This means that absolute value of the indicator
depends on NUMBER OF BARS included in the calculation
while the shape is the same.
Obviously AUD and ARL stocks have different number of quotes
in your database.
Because of this cumulative sum of AD line is calculated
for a different number of bars in each case - so
absolute value differs while the shape remains the same.
Best regards,
Tomasz Janeczko
