Hidden broker fees: which one surprised you the most?

The spread is the obvious cost, but the full bill can include commissions, swap, inactivity fees, conversion charges when your account currency differs from the pair, and withdrawal fees.

Which fee caught you out as a beginner?

• the fee, roughly how much it cost you
• whether it was clearly disclosed in the broker's documents
• how you check costs now

The trading costs guide shows how the three main costs add up per trade.
