In trading, the term any-part-of-order refers to an instruction given by an investor to a broker along with a trading order. This instruction allows the broker to sell only part of the securities assigned to the order, if they are not able to find buyers for the full amount.
Example of an any-part-of-order instructions:
You own 100,000 shares in a company’s stock. When the stock suddenly plummets, you decide to sell as much of your shares as possible. You place a sell order with your broker and include an any-part-of-order instruction. Your broker finds buyers for 60,000 of your shares, but not for the remaining 40,000. Because your order included an any-part-of-order instruction, the broker sells the 60,000 shares for which they have buyers, thus fulfilling the order.
