MultiCharts was previously available for free, the catch is that trades could only be placed manually, no automation. It did however allow for chart trading, and it did a pretty good job at it.
You could place orders by clicking on the chart, with multiple targets. You could attach strategies such as breakouts or limit orders and as bracket orders as well. I didn't like the fat that it waited until the order was filled before it placed stops and targets (bracket).
The software has the ability to connect to a bunch of brokers as well, for order placement.
If your looking for this trading platform, you can probably find the torrent for it. I am fairly certain it still works as a free version to connect to a pile of brokers, but I'm not sure how buggy it is.
I wrote a post a while back on this platform, that it was GONZO. They took the free version off the web site. The paid platform looks very kick-ass if your a full time trader.
If you want to read more about it here is the MultiCharts web page, click on the "Compare editions" on the left side. Also, mouse over the "MultiCharts" on the top to see a huge menu to learn more about this package. I don't use it but if I was a full time trader I would seriously consider it.
