Trading
Trading is buying and selling financial assets with the aim of profiting from changes in their price, usually over shorter periods than long-term investing.
An investor buys a business and waits years. A trader buys a price move and may be out in minutes, days or weeks. Same markets, different goal — and a very different set of risks.

Trading in plain words
A trader picks an asset and chooses to buy or sell it at the current market price.1
Traders can profit from rising prices or, by selling short, from falling ones: if the price drops you can buy back lower and make a profit.2
Trading often can mean profiting from quick price moves, but losses are just as possible.3
How a trade works, step by step
Choose a market
Pick an asset and decide to buy or sell at the market price.1
Pick a direction
Go Long Position if you expect a rise; a short profits if the price drops.2
Fund the trade
In a cash account, pay for purchases with settled funds.3
Understand leverage
Margin trading can lose more than your original investment.3
Review the result
Record whether the move delivered profit or loss.3
Worked examples
Example 1 — A long trade
+$200 before feesA hypothetical trader buys 100 shares at $20 and sells at $22.
| Cost | $2,000 |
| Proceeds | $2,200 |
| Gain | $200 |
Trading aims to profit from rapid price shifts, here a $2 rise on 100 shares.3
Example 2 — A short trade
−$200A hypothetical trader shorts 50 shares at $40, and the price rises to $44.
| Sold at | $2,000 |
| Bought back | $2,200 |
| Loss | $200 |
If the price rises and you buy back higher, you incur a loss.2
Example 3 — Leverage cuts both ways
−60% of equityA hypothetical $5,000 account controls $10,000 of stock on margin; the stock falls 30%.
| Position loss | $3,000 |
| Account left | $2,000 |
With margin you can lose more than you put in — here a 30% fall wiped out 60% of the account.3
