I'm looking for inexpensive or free charting software (delayed or real-time) where you can expand and contract the chart up and down by dragging your mouse, I know this is very typical of most decent platforms but the good ones like TradeStation and ESignal charge too much money. I'm not going to be trading much so I can't really offset the cost with a brokerage account. I need something where you can save trendlines too. Any recommendations?
If you just need charting, Amibroker is very good. If you need more than that, I would recommend Quotetracker.
