I'm kinda new to share trading, I'm only 19, and was wondering if you experienced traders could give me some advice. Ive got a small holding around 12,000 shares in DTE, what do you think would be the best option for me? Do you think its worth it holding and getting the shares in IGAS if the deal goes through, or do you think that its probably better to sell them before DTE shuts up shop on the ASX?

Also what are your estimates for share prices in the near future/ just before and after the deal is confirmed/rejected?

Thanks in advance,
Harry
