think about what you're talking about here terr... literally, a method to hack a broker/vendor api used to authenticate data/execution. this would be a very bad idea. this is no longer misrepresentation, this is criminal hacking. good luck with that if you get caught.
And you are essentially condoning criminal-like behavior by the NYSE to charge different people an exorbitant fee based on how they consume the data. There is no way that this fee would be deemed legal if it were taken to court.
