Fractional shares support

Fractional shares support means that the broker allows you to buy or sell a fraction of a stock - for example only 0.02 stock.

Its availability depends on the broker and the symbol - it is up to broker discretion if it supports fractional shares on stocks and on which symbols exactly.
