I'm not sure how else to convey that the sentiment behind the trade didn't change, not how to say again that the supply and demand in this test was disabled.
exactly.. you didnt consider that sentiment would change. that people would react differently after you change the order matching. you presumed that people would still hand over funds in the same manner no matter what.
if you did include the variable that sentiment would react to your order matching tweeks. then the results would be different.
again how can i convey that sentiment behind a trade WOULD change, and thus the supply and demand beyond the first day of trades would change.. if you just accounted for such deviations
