Algo trading is about having the edge.

The edge is something you have and other people don't.

Enjoy your feature engineering.

(Meaning: selling the same curated data product to many customers undermines its value. Overpricing it and selling only to the selected few, on the other hand...)

But this is algo trading specifically, the scope for curated datasets is larger.

Plus, what stops anyone building on top of a dataset? If this isn't dive ebay value do any third parties add?

A dataset sold to many customers doesn't undermine the price charged by the seller, as there would be no competitive advantage by not using it either.

s/"dive ebay"/"done, what"/

And to clarify the last point:

If a create a dataset for $100 I could sell it to one person for $120, or 6 for $20 - I make the same even if the value to each individual client is reduced; on the other hand, the value to each client versus* making their own is (120-100=) $20 in the first case, but (120-20=) $100 in the second, so fewer clients are likely to "roll their own" competing datasets.

Seems like neural networks would have some advantage here...
