MS POOL
MS POOL is a real-time continuous match dark liquidity pool. It matches eligible orders at or within the best bid and offer, attempting midpoint execution or as close to midpoint as possible. MS POOL employs price/capacity/size/time matching priority, which encourages size and deemphasizes speed (rather than prioritizing time over size).
