To be fair SS seems to be the best deal for private investors, some of these so-called 'advanced' TA packages are outrageously priced, and if you don't need live prices etc.. they amount to not much more than a huge expense for 'paralysis by analysis'.
Sorry about the blank message !!
I echo the favourable comments about Sharescope, have used the package for about four years, good value for money.
I also use Omnitrader which is very good for narrowing down trading prospects - I export end of day data from Sharescope and it works very well
