Question about Forex Taxes

Hello everybody, i have a question about taxes in forex. Lets say i live in UK and taxes on income of more than 150K a year is 45%, but if i travel around the world and trader from all different corners of the world, which country tax will i pay?
Thank you

And brokers that ill be trading lets say are Oanda and FXCM both American companys.

Asking expert level tax questions on a public forum is completely useless. Would you actually follow some anonymous advice? If so you are headed for a world of trouble. Think about standing in front of a judge and pleading “but this guy told me I should do it this way”
