nifty is now trading in very tight range. but i am expecting one sharp bounce towards 18015-18025(black trendline) after that strong selling will come towards minimum 17150-17170(skyblue trendline). so be aware of nifty. traders can sell our levels with 18150 as sl (daily closing basis). option strategy player can sell cmp with above 18200 breakeven sl for next 1000points move
