How much money do you need to start forex trading?

What you really need to start forex trading in the UK: practice first for free, then how small accounts, micro lots and prop firm challenges change the numbers.

The honest answer: nothing to start learning, and only money you can afford to lose when you go live.

Stage 1: free

A demo account, a replay tool and a journal cost nothing. This is where the learning happens. Trade your strategy here for at least 50 trades before you risk anything.

Stage 2: a small live account

Many FCA authorised brokers let you open an account with a few hundred pounds and trade micro lots (0.01). On GBPUSD a micro lot is worth about 8p a pip. With a £500 account, 1% risk is £5, which is a 10 pip stop on about 0.06 lots.

A small account won’t make meaningful money, and it isn’t meant to. Its job is to prove you can follow your rules with real money and real emotions.

Stage 3: scale slowly

Only add money once your journal shows you are following the plan. Keep the same percentage risk as the account grows.

What about prop firms?

A prop firm challenge fee (often £50 to several hundred pounds) gives you access to a larger account if you pass. It is a fee, not a deposit, and most challenges are failed. Read how to choose a prop firm first.
