Fellow Traders & Investors,
My vote goes to Zerodha Pi and following is a comparison and my basis for considering Zerodha Pi as the best trading platform in India. There are certain pluses TradeTiger has over Pi, but overall after using both for the last few days, I think Pi is better.
Check this link to compare Sharekhan vs Zerodha in terms of everything else.
There are currently only these two contenders for the top spot. India Bulls was a close contender to be part of the top 3, but considering how disinterested the promoters are towards stock broking I have left them out.

Memory usage : Pi uses 1/3rd of what TT does.

CPU usage: Pi is generally lesser than TT

Multiple Marketwatch: TradeTiger has an option to add multiple marketwatches, on Pi the workaround is to use workspaces.


Adding scrips: Easier to add scrips on Pi vs TT

Option Calculator
TT has it whereas Pi doesn’t as of now.
Price alerts
Straight forward in TT, a little complex on Pi, you have to use expert advisor or scripted alerts. The advantage with Pi though is that the scripted alert/expert advisor can be used not just for price, but for any technical analysis based strategies. You can have multiple expert advisors searching and scouting for trading opportunities. You can also create consensus report using multiple EA’s.



Research calls and reports
Sharekhan has an active advisory desk, which gives out research reports which are accessible on TT.
Since Zerodha doesn’t do any research, you can’t see any fundamental data on Pi.
Overall after using Pi for the last week alongside TT, I think it is better overall. So my vote is definitely with Pi for the best trading platform in India.
