Watchlists and coding question

[SethW446]

I found a watchlist column called zemacross
https://usethinkscript.com/threads/ema5-crosses-ema13-watchlist.19690/#post-147469
which I like and would like to doctor it some. How do I find other watchlist columns like this, searching in studies was not fruitful.
And how do I get my column into the list of potential columns? I am looking at a list of posts as I type, so this problem is my not knowing TOS as well as I need to. The coding problem is that the label doesn't post what I want it to, and I don't understand. It posts the first half of what I want but not the second half, Xup1 but not Xup2, same with Xdn.
I would love to get this workiing, but more, to understand what I needed to do to make it work. Thanks in advance.

AssignBackgroundColor(if xup1 or xup1 and xup2 then color.green else if xdn1 or xdn1 and xdn2 then color.red else color.gray);

i added a link to your post.
if you click on a post number, in the top right corner, the page will reload with a URL that will take you to that post.

here is a video that talks about watchlists and marketwatch lists.

not sure what you are trying to do....
but , your logic is flawed.

these will have the same outputs. avg2 is a number, that is > 0 , so it will always be true, so xup1 will always be the same as xup2.
def xup1 = close > avg1;
def xup2 = close > avg1 and avg2;

what are you trying to do?

Great! Thanks for the help. They are both numbers but one can be below Price while the other is not. And what I want to know is if one or both is below price, one or both are above price. But I do see your point, and I don't see how to distinguish them. Perhaps a count of how many periods since xup1 switched from above price to below price, and how long ago did both become below price, a momentum measure, perhaps. In fact, the background color would tell above/below, then one count for xup1 and a second for xup2, etc. I think that means potentially 2 colors in a small space. What I thought I was accomplishing was to find the spot where up became down for both MAs separately, so spotting a bounce or trend. I hope I'm clearer.

I watched the video you directed me to. I noted around 2 mins in that the narrator said that I could pick watchlist columns from the column list: "All of the possible column choices appear in the Available Items list".
The zemacross item was one I found and added to that items list, so it must be possible to add some. How? I'll hunt for that zemacross thread, thanks.
