They are about to launch new software named pi. I think the beta testing is going on and very soon it will be launched. it is said that it will have option to link with popular charting software like amibroker. Pi it self is said to have good charting interface. There is option to directly place order from chart.
nest trader has basic charting. As the data is not locally saved, switching between charts take time. There are lot of indicator available but personally I don't use their charts.
