Thanks aditya737 for the query. If ur timeframe is less, I feel SL can be set just below the upper line of the flag. Since my timeframe is for a medium term,the targets set as per the flag pole are 650+. And given the structure,there is a strong support at 490. Moreover placing a stoploss just below the trendline may b risky also going through the lower wicks on the earlier candlesticks.
