1. Where the daily average number of market participants holding a position in the commodity derivative over a period of one year is high, the competent authority shall adjust the position limit downwards.

2. By way of derogation from Article 16, competent authorities shall adjust the position limit upwards and set the spot month and other months' position limit between 5 % and 50 % of the reference amount if:

(a) the average number of market participants holding a position in the commodity derivative in the period leading up to the setting of the position limit is lower than 10; or

(b) where the commodity derivative is an agricultural commodity derivative with a net open interest below 300 000 lots, the number of investment firms acting as a market maker in accordance with Article 4(1), point (7), of Directive 2014/65/EU in the commodity derivative at the time the position limit is set or reviewed is lower than three.

For the purposes of the first subparagraph, competent authorities may establish different position limits for different times within the spot month period, the other months' period or for both periods.
