PRICELIMITS Fills in a struct with default values for offer/bid limits. LIM = PRICELIMITS(LIM, HAVEQ) The final structure looks like: LIM.P.min_bid - bids below this are withheld .max_offer - offers above this are withheld .min_cleared_bid - cleared bid prices below this are clipped .max_cleared_offer - cleared offer prices above this are clipped .Q (optional, same structure as P)
