Hi,

No, manual gives the following formula for ADLine:

Difference = ( AdvIssues() - DecIssues() )/ ( UncIssues() + 1 );
DiffSqrt = IIF( Difference > 0, sqrt( Difference ), - sqrt( - Difference ) );
ADLine = Cum( DiffSqrt );

There is a Cum() function used and it calculates running sum
of all DiffSqrt values since the beginning of the history.

Best regards,
Tomasz Janeczko
