All the above sounds like good advice, If i was to add one small point is, be careful when you start its easy to get confident and think that this is an easy game, esp when you make some big profits with the specs.
just keep in mind that next time it may go the other way, there is no mercy in a market like this- Im sure you will read alot about how ppl have lost some/all of their capital.
Keep your profits quick and sweet if you can, dont get greedy, when you make a few good trades, try and stay focused, take a break and dont trade when feeling too confident - it can be costly.
Also make sure some of your capital is in cash, dont think we are too far from a correction. last thing you want is to get smashed first few weeks of trading :-).
Gluck mate,
Just something Ive learnt from all my mistakes to be honest, thought Id share.
