on new chart window give mini toolbar with combo box to select scrip and exchange ,so we can change sccrip in same chart window, its tedious job to close everytime and open new chart window
overall software is too good, and also give option to set default template.

Nice suggestion. But Stockalyze supports many countries and exchanges and we want to give flexibility to user to select any country and exchange. It's a bit tedious to support quick scrip selection for any country inside a small combo box.
Regarding creating new chart I will suggest to use shortcuts, like Ctrl+N for new EoD chart, Ctrl+I for new intraday chart. It will work much faster than combo box solution. Please give it a try and let me know what you think.

Thank you very much

and also give option to set default template.

There already is a way to set default template. Hit Ctrl+K and set a default template (among other things too).
