why is the trading 212 site in Chinese? Or is it just some issue I'm having with my browser?
From what I've read they are offering some deal to allow you to buy shares commission free, though you're still going to be paying stamp duty...
As the other poster mentioned, what do you mean by short term?
The issue with UK shares is that you have to pay stamp duty, the way around this is to make use of CFDs, however most CFD providers are just bucket shops offering their own two way quote/their own parallel market. I believe interactive brokers and IG Markets are the only ones offering you real quotes/essentially access to the exchange order book and interactive brokers is by far the better value. (there might be more providers now).
