As per the plan BanknIfty was shorted below 17740 levels. Low made was around 17150 which gave a pretty good swing in just 2 days time. Current support as you see was taken exactly at the retracement level. Hence any move above 17450 will be good contrarian long trade for the adventurous ones, and for now that includes me. But be prepared for a quick reversal if that level fails to sustain
