06/25/2021

Improvements

Score

Model Update: The marking the close model now takes into account whether the traders are supplying or taking liquidity during the settlement period, causing higher scores for clusters where traders are aggressively trading and lower scores for when they are mostly being filled passively. In addition to this new feature other scoring features have been adjusted to give greater weight (i.e. higher scores) to traders who have higher percentages of the total market volume during settlement. Additionally, scoring features around price movement have been given less weight to prevent underscoring of aggressive activity that results in smaller price moves.
