Haha, welcome to trading. Everything you’ve been through, the emotions you feel are completely normal. Nearly every trader goes through the same thing you have. 270 quid can be a large amount but it depends on your initial account size. When I started out I lost much more than that so dont worry you’ll get through it.
What you need to do, is never do what you did today. The best way is to get an education first and learn about what trading entails. You can start here. It’s free and includes links, books and the babypips course. Take your time, study hard and you’ll be more confident next time you try and trade. For now though, use a demo account not a live account.
