Binance Futures Will Apply Last Price Protected Mechanism on USDⓈ-Margined BULLAUSDT Perpetual Contract (2026-10-28)

Summary

Binance Futures will apply the Last Price Protected (LPP) Mechanism to the USDⓈ-Margined BULLAUSDT Perpetual Contract starting 2026-10-28 06:00 (UTC), due to spot price divergence and deposit/withdrawal limits across multiple exchanges.
During the LPP period, the mark price is the average of the last 10 seconds' trade prices, calculated every second, and it can move only within a ±1% range each second interval.
During the LPP period, the funding rate cap changes from ±2.00% to ±0.005% starting 2026-10-28 06:00 (UTC), and the funding interval will not switch from every eight hours to every one hour when the cap is reached.
The LPP period ends when BULLA spot prices across multiple exchanges converge and a stable index price can be derived, as determined by Binance; a separate announcement will follow, and the mark price then becomes the median of Price 1, Price 2 and Contract Price.
