great little software program called "Insight Trader
Yes I used Insight Trader many years ago too (not for long). Think it was my first go at trading software and was going to suggest it as I was sure you could download fundamental data within it and backtest with charting/fundametals together.
I guess if your using Stock Doctor that side of Insight Trader has changed since I used it?
...just had a look at their site and they do still have fundamentals within the software. Think it's an extra module but it "Provides the fundamental information of earnings, dividends, franking, net asset backing, shares on issue and debt to equity from which the important fundamental ratios are calculated".
Edit: BTW I don't think data is free as you mentioned. Maybe you got in before they started to charge, not that I'm against paying for data
