Charges for exercution in the first multiasset of those selected for fee payment Only succeeds for Concrete Fungible Assets First tries to convert the this MultiAsset into a local assetId Then charges for this assetId as described by FeeCharger Weight, paid balance, local asset Id and the multilocation is stored for later refund purposes Important: Errors if the Trader is being called twice by 2 BuyExecution instructions Alternatively we could just return payment in the aforementioned case
