Hammer at previous top level. Low of the hammer is very important as it has above average volume. If this low goes it may find support at 17550-17600. However, if the High is taken out tomorrow, then Target is 18000.
Decision : Buying the dip as trend is still Bullish and will look for buying on a dip.
else if the candle closes below low of hammer, will look to sell 17850/17800 CE
