What are the market fees?

Market fees are the fees that we pay to the liquidity provider for opening, holding and closing trades on your behalf. The market fees usually include spreads, commissions, and custody fees. The actual spread values are available in MetaTrader. A commission is 0.01% per one-sided trade (minimum 4 USD). A custody fee is 0.011% per year.
For example, if you invested 5,000 EUR in the OYS Portfolio, then your market fees will comprise a commission of 5 EUR for opening + 5 EUR for closing a position, a custody fee of 5.5 EUR per year, and spreads. Overall, you will be charged 15.5 EUR + spreads for 1 year of holding the investment.
