Dear Nithin Kamath Sir Ji,I've used chart feature of several mobile trading software from upstox,IIFL,ICICI,5paisa ,Zerodha to edelweiss.
But no software is anywhere near to edelweiss mobile trader. Their chart is very very clear.
Edelweiss is freely available on google playstore .One can use it as a guest without paying any penny.
Please ask your mobile developer team to use edelweiss to check their charts quality..and please make zerodha kite mobile software like edeweiss..
Check it out yourself.You will also get impressed.
