I use sharepad at the moment, and would be interested in trying to sort a market breadth indicator out with anyone interested.  Or at least sector strength.

This is the package I'm considering as I'm told it can chart UK Sectors. I assume from your question that market breadth indicators are not included in SharePad's default library, do you know if it's possible to configure new indicators? 

Other systems I've seen are ShareScope and Updata, both look very comprehensive but are more than I want to spend. Another reason to stay with browser based systems is that I use Linux machines and installation software usually requires Windows or Mac environments.

I like the idea of developing my own charts like pcabc does, but I'd still need to source the feeds and I'm not sure I could commit the time and dedication to make it worthwhile.

You can do simple formulas to compare two items in sharepad, but it is not programmable as such.  Isnt there also a problem with a Uk Market sector breadth as they do not contain as many shares as the US version?

There are a couple of problems I find with the UK and yes, this is one of them.  I have a number of the NMX industry / sector indicies (I get the two terms confused, but I don't need to use them often).  Some are much bigger than others.  When I last looked 'Forestry and Paper' comprised of two stocks only.  Others are much larger.   There are more industries / sectors for fewer stocks.  Also, I have manged to find a source for mapping UK stock symbols to industry and sector, but these do not align with the NMX indicies that I have access to.  There does not seem to be an easy way to do things nicely, at least with what data I have at present.

I've not used sharepad so cannot comment.

Totally agree, the NMX sectors are unhelpful for our purposes (Sector analysis) for the reasons stated above. I like the Refinitiv Sectors (Previously Thomson Reuters) for UK markets as there are only ten of them so they don't fragment the market too much. Here's a link to them https://markets.ft.com/data/sectors.

I occasionally like to trade NMX sectors when there are several companies all doing well in a specific industry, for example if home builders are trending up I may buy NMX3720, like an ETF/collective investment.
