Just released the new beta version of QuoteTracker.
http://www.quotetracker.com/betaWhich has:
20 days on intraday charts for TD AMERITRADE Clients, including backfill.
Multiple symbols on the same chart with dynamic or static anchor points (both intraday and historical charts).
The ability to edit individual indicator parameters by just double clicking on the indicator legend on the chart.
Right click on the indicator legend on the chart for options like delete indicator, edit parameters, or in the case of extra symbol indicator, to backfill that extra symbol.
Enjoy, spread the word, and please post bugs found (if any).
