The following are guidance and acceptable practices for compliance with § 150.5 . Compliance with the acceptable practices and guidance does not diminish or replace, in any event, the obligations and requirements of the person to comply with the other regulations provided under this part. The acceptable practices and guidance are for illustrative purposes only and do not state the exclusive means for establishing compliance with § 150.5 .

(ii) The level of the spot month limit for the contract;
(iii) 5,000 contracts (scaled-down proportionally to the notional quantity per contract relative to the typical cash-market transaction if the notional quantity per contract is larger than the typical cash-market transaction, and scaled up proportionally to the notional quantity per contract relative to the typical cash-market transaction if the notional quantity per contract is smaller than the typical cash-market transaction); or
(iv) 10 percent of the average combined futures and delta-adjusted option month-end open interest in the contract for the most recent calendar year up to 50,000 contracts, with a marginal increase of 2.5 percent of open interest thereafter.
