If i open an account in GBP in the uk and then trade the GBP/USD will my profit be in the base currency or the quote?
Most will quote your ongoing profit in your account currency
So does that mean each pip will be worth money from my account currency but if someone had an account in the US each pip would be worth money in USD for the same trade? For instance i could earn 1 english pound a pip while someone else could be earning 1 USD a pip?
No, each pip is calculated on the base currency. The platform simply calculates it back into your account currency. Sounds like you have a fair bit of reading to do so enjoy the journey
