Yes, there is “Swap Points” in case you maintain open positions through overnight.

The typical Swap Points are around -10 for both sides(long and short positions) on FBS MT4 and MT5.

The Swap Points can be charged or credited, and changes by time as it is provided from the interbank market rate.

Swap points won’t be charged to your trading account in case you don’t hold a position of BTCUSD around 00:00 in server time.
