@devarajaraju, In trend analysis positional trading the SL signifies that stock has to close or at least sustain below the SL. In this case the stocks maintained its position above the SL by the end of the day i.e. 543.
Although the stock seems to be week around current levels, it is advisable to wait for few trading sessions to take position as per the buying levels mentioned in the chart.
If the stock closes or remains below 541, trade should be closed otherwise we could expect some upward movement next week.
