We show that the results of ArXiv:1305.6008 on the Fundamental Theorem of Asset Pricing and the super-hedging theorem can be easily extended to the case in which the  hedging options  are quoted with bid-ask spreads. It turns out that the dual elements have to be martingale measures that need to price the non-redundant hedging options correctly  .
We show that the results of ArXiv:1305.6008 on the Fundamental Theorem of Asset Pricing and the super-hedging theorem can be extended to the case in which the options available for static hedging ( hedging options ) are quoted with bid-ask spreads. It turns out that the dual elements have to be martingale measures that need to price the non-redundant hedging options correctly . A key result is the closedness of the set of attainable claims, which requires a new proof in our setting .
