A few more questions
1. Since the a/d applies to a group of stocks, Is there a difference
in the way it is typed or pasted in? Does it go on the indicator
builder screen, the same as other formulas? How do you designate
which stocks to consider?
2. What is the proceedure for making it apply to a specific group of
stocks? e.g. NYSE,NASDQ or better a watch list?
3. I am assuming that if someone want the traditional line, it would
be easy enought to change the formula? as below
Difference = ( AdvIssues - DecIssues)
ADLine = Cum( DiffSqrt );
