Fee

Settlement Fee:

Settlement Fee (or trading fee) is the fee paid by takers (traders) to the makers (LPs). For above/below options, Settlement Fee (SF) is a function of market skew (s), a metric reflecting trade imbalance. Positive skew (s > 0) indicates a market leaning towards either up or down trades, and here, SF linearly scales between a base fee (B) and a maximum fee (M) as per SF Above = B + ((M - B)/S)*s. For negative skew (s < 0), signifying an atypical market, SF inversely adjusts, reducing below the base fee as per SF Down = B - (B/S)*s. This approach dynamically adjusts fees based on market imbalances.

Protocol Fee:

Placing Up/Down trades on Buffer incurs a flat fee for interactions with the Buffer keeper that enables a 2x faster 1 Click trading experience. This is a fixed amount used to cover the keeper fee for opening & closing a trade.

Fee Distribution:

100% of the settlement fee is distributed between the makers (aBLP & uBLP LPs), $BFR Stakers.
