TA/chart, page-116

You need to take account for the 0.018. They last traded at 0.04 today and the buyer is sitting at 0.01, so unless the shares jump in the next few days these may expire worthless and you have lost the 0.018 per option. If you are bullish IMO you would be best to ride the last few days and then exercise. Just means you paid .168 for the shares, rather than take a loss and try and buy the shares more cheaply. Last few days has been disappointing but would be a risk to rely on the shares dipping below 15c.

Hope this helps.
