Fractional Shares Order

Fractional shares allow IBKR clients to build their portfolio components based on dollar amount, not shares. IBKR clients can pick any eligible US, Canadian or European stock (or ETF, where available) and decide how much they want to invest - it's that easy. If the purchase price doesn't result in a whole number of shares, IBKR will buy or sell fractional shares.

To specify a dollar amount for an order, use the size wand in the Quantity field to toggle from "shares" to currency.

Fractional shares allow IBKR clients to divide their investments among more stocks to achieve a more diversified portfolio and put small cash balances to work quickly to maximize potential returns.

The Reference Table to the upper right provides a general summary of the order type characteristics. The checked features are applicable in some combination, but do not necessarily work in conjunction with all other checked features. For example, if Options and Stocks, US and Non-US, and Smart and Directed are all checked, it does not follow that all US and Non-US Smart and direct-routed stocks support the order type. It may be the case that only Smart-routed US Stocks, direct-routed Non-US stocks and Smart-routed US Options are supported.
