According to CoinMeta, Binance announced the launch of two types of seller (short) option profit strategies: covered call (covered call) and cash-guaranteed put (cash-secured put). Both strategies only support limit orders, and the delivery and settlement of the underlying stocks are managed on behalf of Binance users by the brokerage infrastructure service provider Alpaca. Users participating during regular and some delayed closing hours of U.S. stock trading must pass an option suitability test and complete a risk agreement before trading.
