How much do you have to pay to hold a position overnight? How to calculate and view the funding rate for stock derivative contracts?
When trading stock derivative contracts, most people only focus on the opening price, leverage, and transaction fees, while neglecting the third cost: the funding rate. It is a fee that is periodically paid between long and short positions, with the specific settlement period and rate level determined by the rules of each exchange—when your position is opposite to the market direction, you have to pay the counterparty, and when your position is in the same direction, the counterparty pays you. In a one-sided market, this fee can significantly increase. This article clarifies the mechanism of the funding rate, how to read it, and its relationship with the position direction.
