What you said does make sense, thank you Xela! What is level 2, and is it something we can look at somehow? Also I'm curious what you do trade since you don't trade stocks.When you look at "level 2" it becomes apparent: that shows what's for sale, at what prices. To give a very simplified example, if you want to buy 1,000 shares in a company, there might be 400 for sale at $28.00 and then 400 more at $28.05 and you have to take the last 200 of your order at $28.10, so the act of your buying (when the price was $28.00, or $27.98 - $28.02) has left the market with the next ones for sale now at $28.10, or perhaps $28.08 - $28.12 if you want the bid/ask shown.
I don't trade stocks myself, and my numbers might be inappropriate, but I think that example demonstrates the mechanics of why/how "demand" (better known as "buying pressure") actually increases the price at which they're available, for the next buyer after you? Does that make sense?
I think I understand it, but still am wondering if it's the same proportionally, or whatever the appropriate term would be. The number of shares available from Microsoft is so much higher than the mining company example that they're not in the same league, but would it be the same for computer companies and mining companies etc, that have about the same number of stocks available? And is it the same in some conditions but not in others, for example maybe between manufacturers but different between manufacturers and agricultural companies or something like that?My example above illustrates a simplified version of a stock for sale at only one central exchange. But if they're for sale in more than one place, there are also automated trading algorithms seeking arbitrage opportunities and so on, which normalize/balance different supplies anyway.
. . .
Buying 1,000 shares in Microsoft isn't going to move the price at all, because there'll be a huge number of them for sale at the first price you can take, whereas if you want to buy 1,000 shares in a tiny mining company in some small country, that company has far fewer available in the first place, and they're not traded much, so even your 1,000 share deal will effectively raise the price a little (I'm simplifying, but you can appreciate the principle, from what I'm saying?).
