What about charting facilities in Interactive Brokers? It appears primitive.
And how is customer care support?
Not much info available on traderji.
I don't rely on their charting for technical analysis, there are many cheap methods of getting that done but I've never faced platform-issues like other brokers.
Customer-support is very professional & helpful (both phone & live-chat). But if you want call & trade, then IB is probably NOT the option for your friend because call & trade is Rs.2000 (but their platform is so good that I've NEVER had to call & trade in 1.5 years that I've been trading with them).
That's probably because a lot of traders need a lot of intraday leverage, which IB don't provide, so very few people here seem to want to trade with them.
If your friend hasn't already done this, he can just download their platform without opening an account & have a look at the features.
If nothing else, there's always the Internet -
