It's like an order on an Exchange that can be split into smaller blocks - so that someone betting 1000 XCP - should be able to split to match with 10XCP, 100XCP etc. so they can get filled - if they needed to get matched exactly it would probably make the entire system useless.

Okay so by placing the order of 1000 the bear is assuring that he has an additional 1000 XCP to throw down for escrow in case the order gets completely filled. And its not that he has 100:1 leverage and the bull doesnt...

If the delta runs the other way (-1) then the bull gets 11 and the bear gets 9.99, meaning the system eats a cost of the amount equal to the original example.

Unless there's something else I'm not seeing, yes you're right, the proportionality of the payouts seems off. Does your fix suggest removing "wager_quantity" denomination?

I hope you're not trying to match orders with different leverages. You can't assign them the same delta if you are.

CFDs arent legal in my country and I never heard about them until today so please excuse my ignorance.
