Understand the market before you place a trade.

What is forex?

Forex, short for foreign exchange, is the global market where currencies are bought and sold against one another. Traders participate because exchange rates move as economies, interest rates, inflation expectations, capital flows, and political risks change.

Unlike a single stock exchange, forex is decentralized. Prices are formed through a network of banks, liquidity providers, brokers, institutions, and traders. This is why forex trades through sessions across the week rather than through one physical venue.

Currency pairs

Forex is quoted in pairs. In EUR/USD, the euro is the base currency and the US dollar is the quote currency. If EUR/USD rises, the euro is gaining value against the dollar. If EUR/USD falls, the euro is losing value against the dollar.

Pairs are commonly grouped by liquidity and market behavior. Major pairs include the US dollar and are typically the most actively traded. Minor pairs, also called crosses, do not include the US dollar. Exotic pairs combine a major currency with a less liquid currency and can have wider spreads and sharper moves.

Pips, spread, bid, and ask

A pip is a standard unit of price movement. For most currency pairs, one pip is the fourth decimal place. For many yen pairs, one pip is the second decimal place. Some platforms also show fractional pips for more precise pricing.

The bid is the price at which you can sell. The ask is the price at which you can buy. The difference between them is the spread. Spread is a trading cost, and it can widen when liquidity is lower or volatility increases.

• If EUR/USD moves from 1.0850 to 1.0860, that is a 10 pip move.
• If USD/JPY moves from 156.20 to 156.35, that is a 15 pip move.
• A lower spread usually reduces transaction cost, but execution quality and risk controls still matter.

Lots and position size

Forex position size is often measured in lots. A standard lot is commonly 100,000 units of the base currency. A mini lot is commonly 10,000 units, and a micro lot is commonly 1,000 units. The larger the position size, the larger the value of each pip movement.

Position size should be chosen from risk first, not from excitement or account balance alone. Traders usually define how much they are willing to lose if the trade reaches the stop-loss level, then calculate the position size around that amount.

Leverage and margin

Leverage allows a trader to control a larger position with a smaller amount of capital. Margin is the amount required to open and maintain that position. Leverage can make a small market move meaningful, but it also means losses can grow quickly.

For example, if a trader uses high leverage, a small adverse movement can consume available margin faster than expected. This is why professional risk control treats leverage as a tool to be managed, not as a reason to trade larger.

Order types

A market order attempts to execute immediately at the best available price. It is useful when entry speed matters, but the final fill can differ from the displayed price in fast markets.

A limit order sets a price where you want to buy lower or sell higher. A stop order triggers once price reaches a specified level. A stop-loss order is used to define the point where the trade idea is no longer valid. A take-profit order is used to close the trade at a planned target.

• Market order: prioritizes immediate execution.
• Limit order: prioritizes a chosen price or better.
• Stop order: activates after price reaches a trigger.
• Stop-loss: helps define the maximum planned loss.
• Take-profit: helps define the planned exit target.

Market analysis

Forex traders commonly use technical analysis, fundamental analysis, or a blend of both. Technical analysis studies price behavior, chart structure, trends, support, resistance, momentum, and volatility. Fundamental analysis studies the economic forces that can move currencies.

Important fundamental drivers include central-bank policy, interest-rate expectations, inflation, employment data, growth numbers, trade balances, and risk sentiment. A strong technical setup can fail if a major news release changes the market’s expectations.

Risk basics

Risk management starts before the trade. Define the entry reason, invalidation level, position size, target, and maximum acceptable loss. A trade without a defined exit plan can turn a small error into a major account problem.

Many traders use a fixed percentage risk model, where each trade risks only a small portion of the account. The exact percentage depends on experience, strategy, volatility, and personal risk tolerance, but the principle is the same: preserve capital so one trade cannot define the account.

• Use stop-loss levels based on market structure, not random distance.
• Avoid increasing trade size to recover a previous loss.
• Reduce exposure before high-impact news if the strategy is not built for news volatility.
• Review losing trades for process errors, not only market outcome.

Trading sessions

The forex week moves through Asian, London, and New York sessions. Each session has its own rhythm. Asian trading can be more range-bound for some pairs, London often brings higher liquidity, and New York can extend or reverse earlier moves as US data and equity-market sentiment enter the picture.

Session overlap matters. The London and New York overlap is often one of the most active periods for major pairs. Liquidity can also thin near rollover, holidays, and late-week closes, which may affect spreads and execution.

Building a trading plan

A trading plan turns market participation into a repeatable process. It should define which pairs you trade, which sessions you focus on, what setups you accept, how you size positions, and when you avoid the market.

A simple plan may include three approved setups, a maximum number of trades per day, a daily loss limit, and a review process. The purpose is not to predict every move. The purpose is to act consistently when conditions match the plan and stand aside when they do not.
