I know you guys are running busy with Kite up-gradation.
This is some thought that came to my mind.
Can you provide charts also in the publisher API. So that, if someone clicks on any scrip and if he is logged in, then a popup opens up on clicking some kind of button (like Buy Now / Sell Now buttons).
May be it could be simple candlestick chart or it could be the one which you already show when someone clicks on popout button on the kite.zerodha.com charts.
Do give your views. (Alternatively, i was thinking to use yahoo free charts on my website.)
