I trade power and gas in the US and I keep hearing from guys in the industry that have done really well in Nord Pool, but I haven't had an opportunity to research it. It's supposed to be much more liquid than US power markets.
My interest was piqued so I did some quick research. Go to Nordpool.com -> How to become a member -> How to become a member of trading on The Financial Market (Assuming you aren't acquiring generation assets... correct me if I'm wrong) -> Option 1: Exchange and Clearing Member -> Checkpoints -> and then fish around for what you are looking for. Looks like a one time fee to open an account of about 7500 USD and then annual fees of 15000 USD. Commissions for using their electronic platform don't look too obscene.
yeah i 've read all that , but i dont have a couple of million in my account so its unlikely i'll be approved for membership . There seems to be non member options . Which are a lot cheaper. I've emailed two people from Nord Pool for more infomation but none of them have responsed yet ! which is nice of them !
