Perpetual futures do not expire, so exchanges use funding payments to keep contract prices close to spot prices. Binance Academy explains that positive rates generally mean longs pay shorts, while negative rates mean shorts pay longs; Binance’s futures blog adds that high funding fees can reduce profits and increase liquidation pressure.
The mistake many traders make is treating funding as a background detail. If a leveraged position is held through several funding intervals, the cost can become meaningful, especially in smaller contracts where volatility and funding adjustments can change quickly.
Before opening a trade, check four items: the current funding rate, the countdown to the next funding time, whether the contract has a special interval or cap/floor, and whether your margin balance can absorb both price movement and funding deductions.
Funding can also be a sentiment signal, but it should not be used alone. Very positive funding may show crowded longs; very negative funding may show crowded shorts. Combine it with open interest, spot volume, trend structure, and planned stop levels.
