Bill, One can not just graft code from one system to another unless they were designed to a common spec. Let us see who else responds to this thread.Dennis On Apr 28, 2007, at 1:24 PM, wavemechanic wrote: Why not use the code that you developed for your own program in AB or do you believe that AB can't handle it?

Bill I have not searched for such. Before I started using AB last summer, I had written my own personal charting and simulation program. I did adjust all studies for splits. AB was the first program I found which was good enough to entice me away from my own program based on the current and ongoing development of features. Besides, spending so much time programming left to little time for trading. LOL

Hello,
Many things affect a stocks perceived value. Trend lines are drawn to detect when the perceived value of a company is continuing or changing from the past expectations. If a stock split will have an effect on the the perceived value of a company and cause the price to rise or fall then this can be detected by a split adjusted trend line study. Support and resistance lines also are revelent, but only of adjusted for the split. A horizontal price line that was drawn as an entry price would also benefit from being split adjusted. Generally every study I can imagine would only be useful if adjusted for the post split prices.
AB's seems to lack the ability to adjust studies to the adjusted post split historical prices. Leaving a study hanging in the air, perhaps so far from the current price that it can not even be seen on the chart anymore is not IMHO desirable.
How might one go about adjusting study prices for a split in AFL? Would it be desirable for AB to have an option to adjust study prices along with stock prices? Should a request be put in for this feature?
All the data is available to make this adjustment in AB. The study handles are tagged with the date and price, so it can be figured out if a handle needs to be adjusted.

But if you have inserted a trendline manually btw the low point and the high point, how do you think the software will know about it. You are actually drawing a line btw two points in terms of value. No matter what happens to the chart, the line remains static without any change. If you have a scrip which has been split, you will have to re-draw all trendlines afresh.

A bit heavy handed of a reply IMHO --DId you really read the question?
I am generally impressed by the helpfulness of the posters on this
board --you must have had a bad day today.
The help does not tell how to get study trend lines automatically
included in a split operation, or even if it is possible.
I tried this out on a sample, and the trend line was not adjusted, so
the previously trend line was hanging in the air.
The AB split operation is still a bit of a mystery to me. Doing a
backfill operation after a split gets me confused real quick.
Deleting a symbol that was split and then adding it again is just as
confusing. I end up doing a lot of undoing of splits by reverse
split. I have not looked into what I or AB might be doing wrong yet,
but it is not intuitively obvious to me. I have not done an
exhaustive search for answers about split at this point.
