How the market works, from the very beginning
One story, in order, in plain words. You do not need to know anything to read it. Each part ends with what it means for you today.
What a market is
A market is just a place where people who want to sell meet people who want to buy, and they agree on a price. A farmers’ market sells apples. The stock market sells tiny pieces of companies. That is the whole idea. Everything else is detail.
For you: when you hear “the market was up today”, it only means more people wanted to buy pieces of companies than sell them, so the prices rose.
The first shares ever sold
A Dutch trading company needed money to send ships to Asia. Ships were expensive and some sank. So instead of one rich family paying for everything, they sold small pieces of the company to ordinary people in Amsterdam. Each piece was called a share. If the ships came back full, everyone who held a share got part of the profit. People soon started buying and selling those shares to each other, and the world’s first stock exchange was born.
For you: a share is still exactly that. Own one share of Apple and you own a real, tiny slice of Apple.
Twenty-four men under a tree
In New York, traders had been buying and selling shares in the street. Twenty-four of them met under a buttonwood tree on Wall Street and signed a short agreement: they would trade only with each other, and charge a set fee. That handshake grew into the New York Stock Exchange, still the biggest in the world.
For you: “Wall Street” is a real street. It just also became the nickname for the whole business.
Farmers invent the contract
Chicago farmers had a problem. At harvest time everyone had corn, so the price collapsed. In spring nobody had any, so it soared. So farmers and buyers started agreeing on a price ahead of time: “I will sell you my corn in October at this price, whatever happens.” That promise on paper is a futures contract, and the place they met became the Chicago Board of Trade. The idea was safety, not gambling: the farmer knew what he would get, the buyer knew what he would pay.
For you: the “futures” you see on the Tape (ES, NQ, crude oil) are the same kind of promise, now for whole stock indexes and oil instead of corn.
Someone finally keeps score
A journalist named Charles Dow picked twelve big companies, added up their prices and published one number every day so people could tell at a glance whether the market was up or down. That number is the Dow Jones Industrial Average. Later came the S&P 500 (five hundred companies) and the Nasdaq. These are the “the market” the news talks about.
For you: when the site shows SPY or QQQ, that is a way to buy the whole S&P 500 or Nasdaq in one go, instead of picking single companies.
The crash, and the rules that came from it
In the 1920s people borrowed money to buy shares because prices only seemed to go up. In October 1929 they stopped going up, everyone tried to sell at once, and the market lost most of its value. The lesson was brutal and it produced the rules we still live by: companies must tell the truth about their numbers, and a referee, the SEC, watches the whole game.
For you: this is why the site never lets you put more than 10% of your account on one trade, and never lets you trade against the trend. Every rule here exists because someone once lost everything without it.
The teacher and his student
After the crash, a professor named Benjamin Graham wrote down a calm way to invest: work out what a company is really worth, and only buy when the price is well below that. One of his students was Warren Buffett, who used that one idea to become the most famous investor alive. The lesson was patience, not cleverness.
For you: Graham’s rule and ours are the same rule: have a plan before you buy, and let the plan decide, not your feelings.
The market goes electronic
Until now, trading meant people shouting on a floor. The Nasdaq opened as the first market that lived on computer screens. Prices could be seen everywhere at once, and young technology companies (Apple, Microsoft, later Amazon and Google) chose to list there.
For you: every price on this site updates because of that switch. There is no floor any more, only screens, and yours is one of them.
Options are born
An option is a ticket that gives you the right, but not the obligation, to buy or sell a stock at a set price before a set date. The idea is ancient (a Greek philosopher once rented every olive press in town before the harvest for a small deposit) but in 1973 Chicago opened the first exchange where options were standard tickets anyone could trade. The same year, two professors published a formula for what a ticket should be worth, and options became a serious business.
For you: almost every idea on the Tape is an option trade, because a ticket costs a fraction of the stock and the most you can lose is what you paid for it. Learn one word today: a call makes money if the stock goes up, a put if it goes down.
What a market maker is
Imagine a shop that promises to always have a price on the door: “we will buy your share for $99.98, or sell you one for $100.02.” That shop is a market maker. They exist so you can buy or sell any moment you like without waiting for someone else to show up. Their pay is the tiny gap between the two prices, called the spread, and because they are on the other side of millions of trades, that gap adds up. Big firms like Citadel Securities and Virtu do this today. On the old exchange floor the same job was done by people called specialists.
For you: the “Gamma & dealer walls” board shows where these firms are positioned, because when they have to protect a price, that price tends to hold.
Trading becomes cheap, then free
For most of history you paid a broker a big fee for every trade, so ordinary people rarely traded. In 1975 those fees were set free and discount brokers like Schwab appeared. In 2013 a phone app offered trades for zero, and by 2019 every big broker matched it. Millions of new people arrived, many with no idea what they were doing.
For you: free trading is a gift and a trap. It costs nothing to place a trade, so people place too many. That is why this site scores you on discipline and not on how often you trade.
Crashes happen, and the market comes back
In 1987 the market fell 22% in one day. In 2008 banks failed and it fell by half over a year. In 2020 a virus emptied the world and it fell a third in a month. Every time, the people who had a plan and did not bet everything came through, and every time the market went on to new highs. Crashes are not the exception. They are part of the deal.
For you: this is why every trade on this site has an exit set before it has a feeling. You will never have to decide what to do in a panic, because you already decided.
Where you come in
Four hundred years of this story boil down to a few plain truths. Prices move because people buy and sell. Nobody knows the future, so the winners are the ones who manage what they can lose. Rules beat feelings. And the tools that once belonged to a bank now fit on your phone. This site gives you a desk’s tools, a practice account so mistakes cost nothing, and a score that tells you honestly when you are ready.
For you: scroll up to lesson one. The course takes you from here to your first practice trade, one short lesson at a time.
