Bank Nifty and Nifty futures Settlement Cycle on zerodha

Hi I want to trade in Intraday nifty and Bank Nifty or other NSE Equity Futures.So what will be the payment settlement cycle.For eg. If i bought nifty futures of 2 lots Rs.50000 at 1 P.M. and sold it at 2 P.M with a profit of Rs.1000 then will i need another Rs.50000 for next trade lets say at 2.15 P.M or i can trade again in Bank NIfty or Nifty or other NSE equity futures with Rs.50000 or Rs.51000
