Levi --
This is not a direct answer to your question.

However, I know you are a relatively new AmiBroker user.  And so thought you might be interested to know that there is much already in AmiBroker that may do what you want.

1.  There is the AmiBroker Users Guide in .pdf format, here:
http://www.amibroker.com/bin/UsersGuide.pdf
I suggest you download and save it on your computer for quick reference if the future.

2.  View the Users Guide with Adobe reader (free).  Use search to find ADline (if you didn't know about ADline, you could search for Advance first.  That would quickly get you to ADLINE, and you can then start your search anew for adline).  There are 14 entries for adline, the last on page 802 is the most useful, because it contains a link to a Tips newsletter written by TJ, 4/2000:
http://www.amibroker.com/newsletter/04-2000.html

3.  Tip 2. Tutorial:  Working with composites explains how to set up AmiBroker to calculate the adline() function for the market you are interested in.  Notice that you can specify the date range.  You probably want to pick a starting date such that it will be in your data base long into the future and your start value will not keep changing.

4.  BTW, if you may want to read how AB calculates ADLine, see Users Guide page 319.  This is a bit different than your equation, but probably will achieve the same overall effect. (the sqrt() will just give you smaller numbers to work with).

Hope this helps.

How to calculate A/D Line in AB?

Assuming A/D Line = (Adv-Dec)+Previous value of A/D Line.

For data, I have the daily Advances in one symbol, the Declines in another symbol. How would I create A/D Line.

I've read to start with a large value, such as 100,000 then go from there.

For example. On day 1, calculate as 100,000 + (Adv-Dec)

On day 2, calculate as previous value (above) + (Adv-Dec)

etc.

My concern (because I don't know how to code this) is that each time I run exploration, it will calculate from the 100,000 and not the previous value.

Thank You
