外汇交易基础

Forex is the global marketplace where one currency is exchanged for another. It has no single physical exchange: banks, funds, companies and individual traders transact through a network of dealers, which is why quotes can differ slightly between providers.

Currencies are always shown in pairs because money has no price on its own — it only has a price relative to something else. A quote of EUR/USD = 1.1000 means one euro is currently valued at 1.1000 US dollars. If that number rises, the euro has gained ground on the dollar; if it falls, the dollar has gained on the euro.

Because a pair always has two sides, a trader can take a position expecting the rate to rise or expecting it to fall. Neither direction is safer than the other: if the market moves against the position, the result is a loss.

Every pair has a base currency (the first one listed) and a quote currency (the second). The exchange rate tells you how many units of the quote currency are needed to buy one unit of the base currency.

Pairs are not interchangeable. Spreads, available liquidity and how sharply price reacts to news vary by pair, by time of day and by broker, so check the live conditions on the instrument you actually intend to trade.

A pip is the conventional unit used to describe how far a currency quote has moved. On pairs quoted to four decimal places, one pip is a change of 0.0001 — the fourth decimal. Talking in pips lets traders compare movement without repeating long decimal numbers.

Japanese yen pairs are commonly quoted to two or three decimals instead, so a pip sits in a different decimal place. Some brokers also add a fractional digit, often called a pipette. Confirm the quotation format in your platform before you calculate anything in money terms.

A lot describes how large a forex position is. It is the multiplier that turns a price move measured in pips into a result measured in currency.

The larger the position, the larger the monetary impact of every pip — in both directions. That is the whole reason position size deserves as much attention as entry timing.

The bid is generally the price at which a trader can sell, while the ask is the price at which a trader can buy. The gap between them is the spread, and it is why a new position usually starts slightly negative before the market has moved at all.

Spreads matter most to traders who open positions frequently, because the cost repeats on every trade. They also vary: they can widen around major news, at session changeovers and on thinner instruments.

Leverage lets a trader control a position larger than the cash sitting in their account. With leverage available, a relatively small deposit can support exposure to a much bigger notional amount, which is why forex positions are often quoted in lots rather than in account currency.

The part that matters most: leverage changes the size of the exposure, not the probability that you are right. A bigger position makes every pip worth more, so losses grow at exactly the same rate as gains — and can exceed what you expected if the market gaps.

Margin is the portion of your account funds set aside to support an open leveraged position. It is not a fee — it is collateral that is committed while the trade is running and released when it closes.

Exact requirements and thresholds are not universal. They differ by broker, instrument, account type and the jurisdiction your account is registered in, so read the specification for the entity you are actually onboarded to.

Orders are the instructions you give the platform. Learning the five below covers almost everything a beginner needs to enter, protect and close a position.

A market order prioritises speed over price and can fill at a slightly different level than the one on screen. A limit order prioritises price over certainty: it may never fill. A stop order does the opposite of a limit — it becomes active only once price has already reached the trigger. Stop-loss and take-profit orders are attached to a position you already hold and define where it closes.

Practice before risking real money

• Learn the trading platform
• Practice placing orders
• Understand spreads
• Experiment with position sizes
• Become familiar with charts

A demo is a rehearsal space, and it is genuinely useful for the mechanical parts of trading. What it cannot reproduce is the pressure of real money, the hesitation before accepting a loss, or the exact execution and financing conditions of a funded account. Treat a strong demo record as evidence that you understand the platform — not as proof that you are ready for live markets.
