Relative and Passive Relative order types are both Primary Peg orders. IB uses a slightly different convention from Nasdaq (ISLAND), where the REL orderâs offset is always making the order more aggressive, and the PASSV REL does the inverse.
MID-Point peg and Market peg were already available in TWS, and were always native.
