Pym prospects are improving, however, with the constant selling and oil prices falling the stock price is being capped. Should see the price slowly starting to rise once pattersons done selling. Can someone tell me how to buy options for this stock (I use commsec, new to trading).

Also, with oil at $75USD, can anyone estimate what sort of profits pym would be looking at per day at a flow rate of 200bopd.

My calculations estimated at 75 x (1.15 USD - AUD conversion) - $50(costs) x 200(barrels per day) x 0.75 (working interest) gives $5437.5 profit

Can anyone verify if this is the correct way of calculating it?
