Funding Rate: The Cost of Holding a Perpetual Position

Perpetual futures never expire, so exchanges use a funding rate to keep their price tethered to the spot market. Every settlement (most exchanges settle every 8 hours), whichever side (longs or shorts) is dominant pays the other side a small fee. Positive funding means longs are paying shorts - more traders are leveraged long than short, and the crowd is paying for the privilege. Negative funding means the opposite - shorts are paying longs, meaning the crowd is leaning short. Why it matters: funding rate is a direct read on crowd positioning and leverage, not price itself. Extremely positive, overheated funding often precedes long squeezes (over-leveraged longs get liquidated into a drop). Extremely negative funding can precede short squeezes. BTCWEAPON.COM annualizes the funding rate (APR) so a raw 8-hour rate becomes an intuitive yearly cost figure, and tracks it across 1D/1W/1M windows to separate a temporary spike from a sustained positioning extreme.
