Need to learn selecting price levels efficiently to not miss trades like this. Today another sell of Biocon, which was posted some days ago was missed like this by a mere difference of 40 paise from 558(557.60) to 538. Although it is wise to miss trades sometimes and not stretch the rules too much but at the same time the levels selected, must reflect the price activity in the stock. Be patient is the most cliched, the most reflected and the ultimate answer I guess.
