Datatype (LSZ)
A round lot (or board lot) is the normal unit of trading of a security, for example in the UK it is usually 1 and in the US it may be 1, 100 or 10000 depending on the exchange. Each stock exchange has its own regulations regarding round lot sizes.
The LSZ will reflect the primary exchange (EXNAME).
Any quantity less than the normal unit is referred to as an odd lot.
LSZ was added to Datastream coverage in December 2018, it will not be supported for any quotes delisted before this point in time.
