Our Debit Money service, which allows you to trade on margin, is only available to legacy accounts that already had Debit Money enabled. It is no longer possible to change your account to a margin trading profile.
Trading on margin involves investing more than the cash value held in your Cash Account. When trading on margin at DEGIRO, your Cash Account will be negative. With the Active profile, a more conservative approach to calculating portfolio risk is taken. This means you will have less available margin.
With the Trader profile, a less conservative approach to portfolio risk is taken. The Trader profile allows you to trade with more margin from DEGIRO, however this carries greater risk.
