The ability to create watchlists (described as "Favourites" on the DEGIRO platform) and trade directly from the mobile app is useful. The “Favourites” automatically synchronise between the website and the mobile app, which is not the case on some competitors’ apps.
Apart from the easy and simplistic navigation as well as usage, the app offers the following features: Charting toolsThe ability to rapidly open, close and modify positionsMultiple instrumentsReal-time updatesSingle click trades Payment Methods

If you are no longer using your trading account close it with the brokers customer support. And make sure you have a confirmation that any remaining fees are not due. Depending on the type of account you have signed up for you can only be charged an inactivity fee under certain circumstances. As part of a brokers regulation they are required to clearly disclose any inactivity fees. Some brokerage firms may charge inactivity fees as compensation for maintaining your account on their expensive trading platforms, in an attempt to claw back revenue for the lack of commission fees from your trading. Degiro does not charge deposit fees. Although bank / 3rd party merchant fees may apply. You must always review deposit fees as some brokers may charge a fee when you deposit funds from your payment method to your trading account. This is because the payment method which you use to fund your account may accrue a fee. The fee may be a fixed fee when you deposit a specific fiat currency to your account. For example fees are known to be high when depositing funds from a credit card. This is if your broker accepts funding your account via a credit card. A broker may charge a commission fee as a service charge for facilitating the buying and selling of financial assets through your trading account.
Vorsicht - sehr viele versteckte Kosten! Extrem hohe Gebühr bei Dividendenbezug, Werbung ist irreführend (nicht alle Transaktionen kosten die versprochenen €5,90, bei vielen Aktien deutlich mehr).
