You'd have been super lucky to get some shares at where it opened at $38.88 (12:08 EST). It immediately shot up to daily high of $41.95 which is most likely where retail trades would have executed at (assuming you used a market order, which you never should). Always buy with limit orders. See the following screenshot of the graph of today[1] of $WORK for reference.
The advice to generally use limit orders is good though. Rarely would a retail investor need a market order.
Yeah I don't get why market orders even exist. If you're doing something that usually costs thousands to millions, is it ever a meaningful benefit to saving a click or two and a few keystrokes?
If my broker had an option to remove my ability to do market orders (sell or buy) I would immediately enable that.
Have you ever needed to exit a trade in a hurry? Or been buying something on the way up?
What I care about is that it sells.
It's hold-over from the dotcom days when I saw colleagues sell options with a limit order just above the current listed price that never got fulfilled in an a constant down market.
Market order just means sell it at what it's worth right now.
