The right thing is to sell this at the top for the day. But it is difficult to say if the scrip will give you this benefit. It may not rise at all. In such a case, you have no choice but to take a risk. You may have to sell some more at the upper end. The stochastic indicator on the daily chart has been kissing its trigger line for some time now. But even the long term indicators have signalled a sell now. It is a reasonable trade.
