Not as far as I know. You could ask your broker. I could be wrong and level II's might give more insight... But I would think there wouldn't be much of a guaruntee on prices since the market is constantly changing. If strong buying pressure comes on then what ever bundles are available at whatever price can change. I think you have to be really close to the action to give a good answer on something like this.. and you have to be close to the action AS the action is occuring
