A toy implementation of a matching engine. Don't use this in the real world, it's a toy!
The purpose here was to simply show that for a specific use-case of (a) Low volume (b) Unregulated to no need to conform with IOSCO pFMI
Then a toy can do the heavy lifting and there is no need to pay the big vendor tax for a matching engine.
If you have arrived here thinking this is a fully-featured matching engine ready for prime-time, please leave now.
This is not and will never be so!
