Art. 9 of RTS 21

What is the definition of a lot for the application of Article 57(1) of MiFID II to those commodity derivatives for which a lot, as defined in the contract specification by the trading venue, does not represent a standard quantity of the underlying across all maturities/delivery periods for that commodity derivative?

Answer 2

In some derivative markets (mainly related to power or gas), trading venues offer trading in derivative contracts that refer to an identical underlying but have a variety of delivery periods, e.g . annual (calendar), quarterly, monthly, weekly (whole week, working day week and weekend) or daily.

For these contracts a lot or unit of trading, as defined in the contract specification by the trading venue, does not necessarily represent a standard quantity of underlying across all maturities/delivery periods, i.e. the lot size for a daily contract is different from that for a monthly contract as the lot size usually depends on the number of relevant days and/or hours in the delivery period. For baseload power derivatives, this is illustrated by the following table:
