Match orderbook logic for orders inserted into orderbook

[nikhilsaraf]

Is there any orderbook matching logic included?

if I add an ask at price = 100.0 (volume = 5.0) and a bid at price 101.0 (volume = 9.0) then I'd expect that these offers would "cross" and the orderbook would have remaining 1 bid order at price = 101.0 with volume = 4.0 along with one trade which is a sell at price = 100.0 for volume = 5.0

Can you please comment on whether "matching" an orderbook is part of the scope of this project?

In order book trading systems, this is very common trading logic.
In the case of crossings, the price of the pending order in the order book will be the final price.
