Leverage (เลเวอเรจ / ตัวคูณเงินทุน)
Leverage lets you control a larger trade than your own money would allow, using borrowed buying power. It magnifies both gains and losses.
Leverage is borrowed buying power. It lets you open a trade that is bigger than the money in your account. It is usually written as a ratio, such as 1:50 or 1:100.
A ratio of 1:100 means that for every 1 unit of your own money (called margin), you can control 100 units in the market.
A simple example
Suppose you have $1,000 and use 1:100 leverage. You can control a position worth up to $100,000.
- If the position rises by 1%, the gain is $1,000. That equals 100% of your $1,000.
- If the position falls by 1%, the loss is also $1,000. That would wipe out your whole account.
Without leverage, a 1% move on $1,000 would be just $10.
Why it matters
Leverage magnifies both profits and losses. It does not change how the market moves. It only changes how big your position is compared with your money. Higher leverage means a small price move can have a large effect on your account.
Common beginner mistake
Many beginners think a higher ratio is better because it gives more "power". In fact, using too much leverage is a common reason accounts are closed out quickly. A safer habit is to choose a position size based on how much you can afford to lose, and to use a Stop Loss. The maximum leverage available is not a target you have to use.
