NSE( National stock exchange) is one of the leading stock exchange in India, headquarters in Mumbai .It is the most trustworthy & profound exchange among all exchanges in India.
I prefer to trade in NSE listed companies over BSE( Bombay stock exchange - It is the oldest exchange in asia.)
NSE have various segment for the investor or traders who invest money in willing to make profit from the market like Equity cash, Future, Option, Index F & O, Currency derivatives.
You can trade Intraday( Same day trade) or Positional trade( Hold the position for a long term) . Index of NSE -Nifty 50 ( It is group of top 50 companies) shows liquidity of Indian economy like Sensex( group of top 30 companies) in BSE.
As we all know Market open at 9:15 am & close at 3:30 pm from Monday to Friday. we can trade & make position in this interval only.
It have very transparent process to Issue IPO( Initial public offering - means first time launch their stock / shares in the market.) in NSE via SEBI norms( Securities and Exchange Board of India-A regulatory firm involved in financial market).Most of the company Launch their IPO in NSE to make money from market & grow their business.
Plus if you so much interested in financial market & want to learn bout it, they provide various professional courses to get in-depth knowledge of capital market so you can become, professional researcher, Advisor in stock market .
So if you trade or invest in stock market always choose NSE listed companies.
