You should join Tom Hougaard's Telegram group (free, of course). You can see how he handles trading large sums (adds to winners, also uses a CFD). He also has a YouTube channel. Talks a lot about psychology. Best stock swing trader is Kris Kullamaggie. He trades HUGE size with a 25-30% win rate. He has a Twich stream and YouTube channel. Tom is the best short term index and futures trader I've seen. Both will help with the things you fear. I would never recommend a pay service. These two make so much money it's ridiculous.

Of course stoxx bounce the moment i say that going to put my stop just above this bounce on the swing trade
