How does a retail trader optimize fill execution price on an illiquid wide spread using mid-point pricing?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Mid-point pricing lets a trader peg or submit a limit order at the exact midpoint between the national best bid and offer, often improving fills on illiquid wide-spread options compared to crossing the full posted spread to a market order.
How it works
Some exchanges offer midpoint peg order types or auction mechanisms that seek to match buyers and sellers near the NBBO midpoint, reducing the effective cost of the displayed wide spread.
An example
On an option quoted $1.00 bid / $1.40 ask, a trader entering a $1.20 midpoint limit order may achieve meaningful price improvement versus paying the full $1.40 ask.
Risk & limitations
Midpoint orders on illiquid contracts may simply never execute if no counterparty is willing to trade at that price, leaving the trader without a fill.
