No, to ensure an equitable trading experience for traders across the platform, we enforce a minimum  1 USD notional amount for entry orders.
Starting from November 24th, 2022, we will also reject securities orders that are smaller than 1 USD in notional value for quantity-based fractional orders.
Alpaca does not make recommendations with regard to fractional share trading, whether to use fractional shares at all, or whether to invest in any specific security. A security's eligibility on the list of fractional shares available for trading is not an endorsement of any of the securities, nor is it intended to convey that such stocks have low risk. Fractional share transactions are executed either on a principal or riskless principal basis, and can only be bought or sold with market orders during normal market hours.
