Anyone know of a real-time charting service that allows you to compare 2 stocks each with it's own scale for price? This would come in handy if I'm comparing a $100 stock with a $1 stock....
you could probably do it in amibroker with the foreign symbol function. Convert the prices into % change and then plot. Not alot of work to do.
You might want to try QuoteTracker. If I remember correctly, it had translucent charts. So you could put multiple chart windows on top of each other. Personally I have not used QT for quite some time (~3 years, when they crippled the interface to Stockwatch data source), so I am not sure, what it can do these days. Maybe one of the current QT users can confirm.
