You can trade US company stocks through the Plum app by placing “Market Orders”.

A Market Order is an instruction to buy or sell your chosen stock at the best market price currently available to us (as opposed to “Limit Orders” or “Stop Orders”, which allow you to queue potential trades, to be executed on the condition that your stock reaches a set price in the future).

A Market Order ensures an execution, but it doesn’t guarantee a specific, set price.
