What Is the Funding Rate, and Should Day Traders Care?
What the perpetual futures funding rate is, how it is calculated, who pays whom when it is positive or negative, how often it settles, and when day traders should care: holding across settlement, what extreme rates reveal about crowding, and how funding shows up in live PnL.
The funding rate is a periodic payment between longs and shorts on perpetual futures that keeps the contract price close to spot. For day traders it is usually a small cost, but it matters in two cases: when a position is held across a settlement time, and when the rate is extreme.
What the funding rate is
Perpetual futures never expire, so exchanges use a funding rate to pull the contract price back toward spot. When the rate is positive, longs pay shorts; when it is negative, shorts pay longs. The money moves between traders; it is not an exchange fee.
On OKX and Binance, major contracts usually settle every 8 hours, and some contracts settle more often; check the contract details page on the exchange. Only traders holding a position at the settlement moment pay or receive funding.
How it is calculated
Funding per settlement = position notional value × the current funding rate. Notional is the position's total value at the mark price, not the margin you put up, so higher leverage means more funding for the same margin.
A hypothetical example: a long with 10,000 USDT notional and a 0.01% rate at settlement pays 1 USDT; at −0.01% it receives 1 USDT. The numbers only illustrate the formula.
When day traders should care
First, when a position spans a settlement time. Most intraday positions close within hours and may never hit one, but if you enter just before settlement on the paying side (for example going long when the rate is high), you pay one more time.
Second, when the rate is extreme. A rate far above normal means a lot of money is crowded on one side, and sharp reversals and wicks become more likely. That calls for strict stops, not adding to the crowded side. Langlang Flash flags coins with extreme funding in real time.
How funding appears in live PnL
Net PnL on this site's Live Performance page comes from exchange settlement and already includes fees and funding. Users' live accounts have closed 94 trades with a combined net PnL of +134.03 USDT, and that figure includes every funding payment received or paid.
Per-trade ROE = net PnL ÷ margin, also measured after funding.
- Does the exchange collect the funding fee?
- No. Funding is paid directly between longs and shorts; the exchange takes nothing from it. What the exchange charges is the trading fee.
- Is a negative funding rate good?
- Shorts receive funding and longs pay. A negative rate usually means the market leans short, but it does not by itself predict direction.
- If I only hold between two settlements, do I pay funding?
- No. Funding applies only to positions held at the settlement moment.
