Have you read our patent submissions and compared differences? Last time I checked I have not submitted any. BTW they cannot be the same. The point is, a person from the financial side has submitted a patent. And it all started with an algo, and mine also has a parsing schema. Although different than IEX.
I have the internal business method patent procedure and it's a lot more complicated than that. I agree a trade cannot be patented but a complex unique system can. As long as it meets specific criteria and rules as stated in the doco. For example internal database meta model and schema can be patented. I know all the peanuts will bring up enforcement but that's outside the scope of this thread.
