For instance, if your order is opened before 21:00 GMT and closed after 21:00 GMT on the same day, rollover will happen, swaps will be charged.
Trade open time: Monday, 2020-04-06 20:59:59
Trade close time: Monday, 2020-04-06 21:00:01
Swap charged: 1 day
However if your order is opened after 21:00 GMT and closed before 21:00 GMT of the next day, rollover will not happen, swaps will not be charged.
Trade open time: Monday, 2020-04-06 21:00:01
Trade close time: Tuesday, 2020-04-07 20:59:59
