## How Do ‘Trading Costs’ within the ETF Differ from the Stated Expense Ratio?

The stated expense ratio covers the fund's operating expenses, management fees, and administrative costs. Trading costs, which include brokerage commissions and the bid-ask spread incurred when the fund buys or sells its underlying assets, are not included in the expense ratio.

These costs are reflected indirectly as a reduction in the ETF's overall performance.

This striking abstract composition serves as an archetype for visualizing the simultaneous propagation of delta and vega risk across an active options trading book tied to digital assets. It metaphorically represents the dynamic equilibrium required in managing complex layered derivatives exposures such as spread trades or butterfly structures executed against on-chain perpetual contracts. The illuminated core suggests the pricing engine or oracle feed driving real-time stochastic volatility models used for valuing asset-backed tokens or synthetic assets. Specifically, the opposing forms may symbolize the dynamic interplay between the bid ask spread resolution in limit order books and the continuous requirement for robust collateralization ratios within DeFi lending protocols to prevent immediate liquidation cascades across cross-margined positions, essential knowledge for advanced crypto derivative participants navigating Theta decay and curvature risk."
