for trading you should open a trading a/c along wiht demat a/c. some brokers will allowe you to trade with a trading a/c only. [ ie. without demat a/c] but its safe and practice to open a dp a/c with trading a/c.
you can do all intraday/short-term - long term etc as u wish with parameters of your broker. I suggest kotak securities ltd.
paper trading means to play with figures without cash. just a testing method of your trading plans and strategy.
active trading is one which involves cash and emotions.
begin with small capital, gain the patience, workout profit/loss every day/weekly basis. Never take intraday trading as a fun. its a serious business and the risk/reward ratio is 70 : 30
happy trading
