Thanks, appreciated.  I'd suggest you look around for charting packages and data sources.  By packages I of course include charting sites.  I'd suggest that you don't discount the US as over the last 5 years it has been very strong compared to the UK.  But you need to be very wary of foreign exchange costs and order types (at least for your trading account) as they have bit me hard.  I'd suggest looking at the thread https://www.stageanalysis.net/forum/Thre...-Indicator,  This gives examples of how to calculate the Mansfield relative strength.  

Also worth a look:
