A "simple 4:1" split as you so dismissively refer to it, enhances the a company's equity by a multiple of 4 and also the quantum of  float that is moving around in the market, though not necessarily by the same quantum. That my friend, changes the demand-supply dynamics of the company's stock as also the perceptions of the market participants about it. Which I hope you will be kind enough to concede will start impacting the price movements too. So in summation yes a split warrants new trend lines. However if you want to stick to an analysis that was relevant to a situation that existed in the past, and not re-do the analysis in the light of the changed situation, all you have to do is let the old trend lines remain.

Hello,
 
If you use AFL coding to draw the trend lines, it gets changed because after you split, new Highs and Lows are used to write new trendlines.
 
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.
 
Cheers

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.
