# FIX field for maker orders

I'm unsure if this question is fit for this particular Q&A board. Please direct me otherwise.

Is there a prescribed field in FIX for new order messages (NewOrderSingle et al) which indicates willingness to participate in a trade only as a maker (or only as a taker)?

FIX Field ExecInst has a ParticipateDontInitiate value ('6') since at least version 4.0.
