    • Including options market information leads to more accurate estimations of the futures market's implied spread and permanent spread component.
    • In-the-money options trades (high delta) contribute more to the adverse information cost component than out-of-the-money options trades (low delta).
    • The adverse information cost component displays a U-shaped intraday pattern, decreasing sharply at the trading day's close.

    Conclusions:

    • Options market information is vital for a comprehensive understanding of futures market microstructure.
    • Informed trading, particularly through options, significantly influences futures price discovery and bid-ask spreads.
    • The intraday dynamics of information costs in futures markets are complex and exhibit specific patterns.
