X90 does not charge for any dealing commissions.
Unlike other service providers who also charge commissions on each trade.
If you hold a position open after a certain hour, a funding premium is either added or subtracted to your account to cover the benefit/cost of the associated funding. The Premium Time (usually time of market close) for each instrument is shown under the market details page.
To view the funding premium for a specific instrument, go to the main platform screen, select an instrument and press "Details" on the far right of the row.
Note: if a position is opened on a Friday and held overnight until the following Monday, the next trading day, the funding premium is usually three times the daily amount to cover the entire weekend period.
