What is a powerful software for stock market analysis?

I like Sharekhan trade Tiger which comes with Sharekhan demat account . It is pretty exhaustive with all possible oprions to do chartical analysing, option chain analysing etc. 

It doesn't take a humongous amount of disk space and can easily be installed on home desktop or laptop computers. 

It is equally beneficial for all types of traders and investors. 

It's depends upon your way of analysis. You can use SHAREKHAN, MOTILAL OSWAL, ANGELONE, TRADING VIEW, ZERODHA software. Different dmat account have different individual software indicator strategies. Some indicators may not be available in other dmat account. But for the time being you can use Sharekhan & in zerodha as well. 

If you are comfortable with analysis startergies then you can use other dmat accounts software chart analysis facilities . 

The result depends upon your trading strategies for both longterm and short term goals.
