The daily trend is judged from the closing index of the day. Here you don’t have to see the intra day trend or the weekly trend. Whenever the trend changes, take the Index future (or short as the case may be) and take at least 7 trades of it continuously. Index mentioned here refers to the NIFTY SPOT or BANK NIFTY SPOT index and not the Future Index, so we go on taking the Index Future whenever the trend of the Nifty or Banknifty Spot changes.
