What is an option? Flow's 30-second definition
In under 30 seconds, Flow gives one of the cleanest plain-English definitions of an option you'll hear — a right, not an obligation — and why the leverage that makes them tempting cuts both ways.
An option is the right, but not the obligation, to buy or sell a stock at a fixed price by a certain date. People use them for leverage — it takes less money to control more — but that same leverage means you can lose more, and an option that never reaches its price by expiration expires worthless.
A right, not an obligation
Flow's definition is worth memorizing: an option is "a right, but not the obligation, to purchase or to sell a stock at a fixed price by a certain date." You're paying for optionality — not committing to a purchase.
Leverage cuts both ways
Why bother? "It takes less money to make more — there's more leverage included with options." But Flow is just as clear about the other edge of that blade: "if you can make more money, it's an opportunity that you could lose more money." If your contract expires before the stock reaches your strike price, "it'll expire worthless" — you lose what you paid.
Calls and puts, in one line
Two flavors. A call is the right to buy at your fixed price — you want that when you think the stock is going up. A put is the right to sell at your fixed price — the one you want when you think it's going down. Everything else in options is built on those two words. Full breakdown of calls vs. puts.
The four things every option has
Read any contract and you're looking at four numbers: the underlying (which stock), the strike (the fixed price you can buy or sell at), the expiration (the deadline), and the premium (what you pay to hold the right). Change any one of them and the price changes. That's it — no fifth secret.
What you can actually lose
When you buy a call or a put, the most you can lose is the premium you paid — full stop. If the stock never reaches your strike by expiration, the option expires worthless and that premium is gone. That's the trade-off for the leverage: small money to control more, but the whole ticket can go to zero. (Selling options is a different animal with different risk — not where a beginner should start.)

Common questions
Can I lose more than I put in?
Not as a buyer of a call or put — your premium is the maximum loss. Selling (writing) options is where risk can run larger, which is why beginners start by buying, not selling.
What happens at expiration?
If the option is out of the money (the stock never reached your strike), it expires worthless. If it's in the money, it settles for its value — most traders sell it back before expiration rather than exercise.
How much does one option cost?
The quoted price is per share. One standard contract controls 100 shares, so multiply by 100 — a $2.00 option is $200 for one contract. Here's the ×100 rule on a live trade.
