Where (trading-platform, data-provider) can I find the most actual realtime-quotes (forex, stock-indices) exclusive of other requirements to trading/chart-Software? I mean really 'realtime' - not delayed.
Try interactivebrokers.com. there very good. for live quotes your going to need to open an account with someone regardeless unless you just use someone like esignal for charting. ib is very cheap 10 a month for all data real time and charted it for free in quotetracker.com. 2000 to open the account minimum though
