IEX Discretionary Peg Order

Background: 

IEX offers a Discretionary Peg™ (D-Peg™) order type which is a non-displayed order that is priced at either the National Best Bid (NBB for buys) or National Best Offer (NBO for sells). D-Peg™ orders passively rest on the book while seeking to access liquidity at a more aggressive price up to Midpoint of the NBBO, except when IEX determines that the quote is transitioning to less aggressive price

D-Peg™ combines elements of Midpoint Peg, Primary Peg, and traditional discretionary order types.
 
Information about slow and predictable changes in the NBBO are detected in IEX's Crumbling Quote Indicator and provides D-Peg™ orders with an instruction to stop seeking access to liquidity at a more aggressive price until the quote returns to a stable state.
