Generally speaking, it is the overnight fee incurred by holding an open position overnight after the order is placed on the same day and before the settlement of the exchange.

You may have heard several expressions: overnight fee, warehouse interest, position fee, extension fee, etc. In fact, these are all the same meaning, but there are many ways to express them.

And no matter whether it is a working day or a rest day, as long as you hold a position for the night, you will be charged, and the overnight fee will be settled on a daily basis, whether it is long or short.

Overnight fee can be regarded as a kind of cost in spot natural gas. The holding fee of spot natural gas is generally two ten thousandths, and the calculation method of overnight fee of spot natural gas is: opening price x contract unit x number of positions x holding days x 20000. If you hold a position overnight on Friday, there will be a three-day overnight fee on Monday.
