How does buying actually work?

Asking and being answered

The cork board at one moment. Sellers pin the least they will take, buyers the most they will pay, and the gap between the best of each is the spread. A market order takes the best seller now; a limit order waits at its own number.

You do not buy a share from the business. You buy it from another owner who wants out, and you reach them through a broker: the company whose app or website you use, which carries your instruction to the market. That instruction is an order.

At any moment the market holds two lists. Buyers say the most they will pay, and the highest of those is the bid. Sellers say the least they will take, and the lowest of those is the ask. The small gap between them is the spread.

A market order says: buy now, at whatever the cheapest seller is asking. It is fast, but the number is not promised; in a quick moment it can fill higher than the screen showed. A limit order says: buy only at my number or better. The number is promised, but the fill is not; if no seller comes down to it, nothing happens.

Once you own the shares, you hold a position, and the price you paid is your entry. Every result from here on is measured from that number.

Said with a food truck

The slip owners put up a cork board on the side of the truck. Owners who want out pin notes: "will sell at sixty-six", "will sell at sixty-seven". People who want in pin theirs: "will pay sixty-four", "will pay sixty-three".

You can take the cheapest seller’s note right now and pay sixty-six. Or you can pin your own note at sixty-four and wait for someone to come down to you, which may be in an hour, next week, or never. Your friend’s cousin keeps the board tidy and makes sure the money and the slip both change hands; that is the broker’s job.

That is step five. The next chapter is the one most books skip: what it looks like when the number goes the wrong way.

Nothing here is advice. The whole ladder is on one page; the app behind it is free to start - the door opens to any address. Education only. Pumpstradamus is a paper trading app: no real money is traded, and we are not a broker or an adviser.
