Hello,
So I kind of brought the options by accident.. I put in an offer for both as I'm new to this and I learn better by doing.. anyway on the first day I got the heads.. and then forgot I had an offer on options.. and they dropped and now I have both.. which is awesome cuz I will make some money now if I sell and my other stocks are long term.. but I have no clue about options and what to do with them.. should I sell them high or exercise them (I have no clue what that means and everything I read about it makes it as clear as mud).. I am with commsec and what I read was they need verbal approval.. but I have no clue what I would be agreeing too. Can someone do me a favour and explain in English.. it's not a huge amount of money as I am still learning and decided to go small till I know what I am doing..
Cheers...
