Stockopedia price increase

[absolutezero]

Just had an email from Stockopedia telling me they are increasing their prices from £240 a year to £260 a year.
I keep track of stuff on there but also have my spreadsheets.
I have used their data in the past and do find it useful but I'm moving towards ITs and index based ETFs rather than individual shares... Stockopedia is starting to be not much more than a very expensive spreadsheet for me now.

Considering cancellation but before I do:
Does anyone have any alternative web based things that do charts? How do these compare on price?

In particular, I would like the ability to
1. calculate moving averages? 10 month especially so.
2. compare price to NAV for ITs.
