Yesterday afternoon I sold shares in a stock through my online broker. As soon as I clicked Submit, up popped a message that the order was filled!!!
In the past, this process has taken minutes or even hours, especially for odd lots like mine. It's all done by computers owned by the really big guys who are taking advantage of the small ups and downs of the market. The cents part of my price was .1902. The stock closed about five cents higher.
And to think that many financial articles talk about investors doing this or that to the market. Buying a stock and then selling it a few minutes later is not investing. Recently I read that the majority of stock trades are done by computers, not people.
