Enum ShortPutCollateral 

#[non_exhaustive]
pub enum ShortPutCollateral {
    Strike,
    StrikeLessPremium,
}

How much quote a short put holds on the SimulatedVenue, which takes only fully secured shorts: a put written against cash set aside to buy the underlying at the strike if it is assigned. See its # How an option is accounted.

Brokers differ on whether the premium the sale receives counts towards that cash. A short call holds the underlying it would deliver, which the premium cannot pay for, so this setting does not apply to it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Strike

The account must hold strike × quantity × contract_size of quote before the sale, and the premium it receives does not count towards it. The default, and the stricter rule: a cash-secured put as the options clearing house’s risk disclosure defines it, and as Interactive Brokers holds it in a cash account.

StrikeLessPremium

The premium the sale receives counts towards the strike, so the account needs only strike × quantity × contract_size less that premium beforehand. Alpaca holds a cash-secured put this way. A limit sale resting on the book holds the strike less the premium at its limit price, and gives back what a better fill does not need.
