Well my circumstances are going to be of very limited benefit to others for a number of reasons, (a) I trade EOD stocks on the ASX (b) I trade from a Super account, USA equivalent would probably be an IRA Account and this has certain conditions which hamstrings trading (c) I use Amibroker as my main analysis platform but source info from a wide variety of other places, Barchart, Googlefinace, Yahoo, Commsec for live data and watchlists, Norgate for download data, Investsmart, AFR (Australian Financial Review), WSJ.com, Marketindex.com, and Walt Disney where I play the mickey.Can you at least give us an alternative? Preferably something you use and you yourself pay for. Include mkt data source and execution options.
