How to trade profitably without any software or a broker, in stock market?

You need a broker, the public does not have direct access to the stock exchange. You can use online services like Etrade and do it your self, or hire a broker. It may cost a little, but it's worth it. Having someone who knows what they're doing and will not rip you off for their service will be a benefit to you.

I'm not a expert on this subject: but if you don't want to use software then hiring a broker is what you want. You should still use some software so you can monitor your progress with your broker if you can.
