What platform is best for forex trading in the UK?

It really depends on your skill level, if you’re experienced and you’re looking to trade exotic pairs - then someone like IG will probably be best. If you want a basic interface, easy to sign up then capital com is probably a better choice. Spreads are slightly more than IG, but it’s very easy to use and the app is quality. The good thing about IG is the fact you can also buy crypto, stocks and have an ISA as well!
