Professional client
Professional client status lets you go beyond retail leverage caps, in exchange for losing several protections reserved for retail clients.
To be classed as professional on request under EU and UK rules, you normally need to meet at least two of three criteria: an average of ten significant-size trades per quarter over the last four quarters, a portfolio of financial instruments and cash deposits above €500,000, or at least one year working in the financial sector in a role that requires knowledge of the products.
In exchange for higher leverage, you may lose negative balance protection, the 50% close-out rule and some disclosure safeguards.
Be wary of brokers that push this status on beginners: it is often a sign of an aggressive sales model.
