Cboe to introduce Quote Depletion Protection tool
The tool is poised to offer new protective capabilities and increase the efficacy of Cboe’s Midpoint Discretionary Order.
Cboe Global Markets, Inc today announced it will introduce enhancements – including a new Quote Depletion Protection (QDP) feature – that would provide new protective capabilities and increase the efficacy of its Midpoint Discretionary Order (MDO).
Pioneered by Cboe in 2012, the MDO is an order type that is designed to enable participants to trade more often with maximum price improvement. MDOs allow participants to post displayed or non-displayed liquidity at the National Best Bid or Offer (NBBO) with discretion to execute up to and including the midpoint of the NBBO.
Market participants will have the choice to deploy QDP on MDOs entered on either the Cboe EDGX or EDGA Equities Exchange. Once activated, QDP would disable discretion for a limited period to help prevent participants from exercising discretion in undesirable circumstances – i.e., buying right before a price declines, or selling right before a price rises.
Aggressive sweeping orders and oversized orders may result in market impact risks and adverse price movements after executing a trade. QDP is set to equip fundamental investors with an additional trading tool to help protect against such adverse selection risk and enhance trading outcomes when using MDOs.
QDP would track significant executions of orders that constitute the best bid or offer on the EDGX or EDGA Book. The mechanism would be activated if the best bid or offer displayed on EDGX or EDGA is executed below one round lot. During a QDP Active Period, an MDO would not exercise discretion for a specified period of time. If participants choose to not use QDP, an MDO operates and functions as originally designed.
In addition to QDP, market participants will be able to enter MDOs with an offset instruction to the NBBO. This is designed to enable participants to specify more or less aggressive pegged prices for MDOs resting on the order book, thereby increasing flexibility when using this order type. MDOs with QDP will default to a less aggressive offset of 1 Minimum Price Variation, but can be increased to a greater amount if a larger discretionary range is desired. Member firms will have the flexibility of choosing an offset that is consistent with the urgency and/or client’s order handling instructions.
