Improvements

Trade Surveillance

The model identifies and scores potentially abusive market behavior related to the Indicative Opening Price (IOP) during the pre-market open period on CME. It specifically looks for instances where buy orders are placed above the current IOP or sell orders are placed below it ("crossing the IOP"). If such a crossing occurs and the order is subsequently canceled before market open, the model assigns a high score, with higher scores for multiple cancellations after an initial crossing.

These limits provide notifications when certain risk levels are approached, but they do not automatically prevent trades. See our documentation for more details.
