Why is my account charged 3 times for open positions on Wednesday?

Rollovers/Swaps are applied based on the ‘value’ date and not ‘traded’ date. The value date for transactions is usually two days subsequent to the transaction date thus the value date for Wednesday is Friday. Therefore, if the position is not closed on Wednesday and is closed on Thursday, the value date is moved from Friday to Monday, thus you will be charged for 3 nights. Example of value dates: 

Open trade Close trade No. of ‘Rollover’ days
Monday Tuesday 1
Tuesday Wednesday 1
Wednesday Thursday 3
Thursday Friday 1
Friday Monday 1
