It can’t be taken seriously [I]as you’ve defined it above[/I], perhaps.
That’s because your definition is oversimplified and inaccurate. A more expanded version (e.g. observing that the “ask price” is the price specified by the seller as the one at which his holding is for sale and the “bid price” is the price specified by the buyer as the one which he’s willing to pay, in the quantities specified) avoids that problem.
It’s gradually becoming increasingly clear from your threads in this forum that you’re almost obsessed by the precise and pedantic meanings of the terminology involved (even more than I am, myself, and let me tell you that’s saying something!), and that that’s significantly holding back your trading education. I don’t pretend to understand why, though. As I’ve observed in other threads, I wish I could help you along, much more, with your understanding of these and related issues, but I just can’t. And I strongly suspect that nobody else here can, either. :8:
No; I wouldn’t, because it’s an irrelevant waste of time, to someone who wants to learn how to trade successfully.
