Interesting article,thanks
The point about euronext putting fines on over inputs/fill is BS though.
They charge for messages sent.
1 message is counted for a 1 lot or a 10,000 lot.
Firms currently abusing the system are inputting in huge orders to game the system and never complete.
So if the fines were charged per lot inputted NOT messages generated then it would work.
Presently it's an exchange/algo workaround to say to people concerned "we're doing all we can",when in fact they aren't.
