The current market price is at 264.20 and the candle formed on a daily chart is spinning top which clearly is an indecision candle. Also, the price closed below 200 Moving average which clearly indicates sell. 255 is clearly strong support and if the price reaches the level look for buying opportunity with any reversal candlestick pattern.
Look to buy when NIFTY50 is in alignment with your long position. DO not buy when NIFTY50 is bearish wait for NIFTY50 to be bullish and then you have a long position so that the reward can be more than 1:2.
