Trading has its own language. Most of it is not as complicated as it looks. The problem is that encountering an unfamiliar term mid-article, or worse, mid-trade, creates the kind of confusion that costs money. This page covers the trading basics every beginner needs before placing a first position: how price direction is described, how to read a basic chart, how orders work, how risk is managed, and what leverage actually means in practice. Work through it once and the vocabulary will make sense. Come back to specific sections when a term comes up again in context. That second reading is usually where it sticks. If you are earlier in the process and still working out what trading is or how to get started, what is trading and how to start trading cover both of those questions from first principles.
Between 74% and 89% of retail clients lose money when trading contracts for difference (CFDs), with average losses per client ranging from €1,600 to €29,000, according to analysis across EU jurisdictions published by the European Securities and Markets Authority (ESMA).

When traders say a market is bullish, they mean prices are rising or are expected to rise. When they say bearish, they mean prices are falling or expected to fall. Bullish comes from the image of a bull thrusting its horns upward; bearish from a bear swiping its claws down. The imagery is old, the usage is universal. A trader who is bullish on a stock believes the price will go higher and may buy it. A trader who is bearish believes the price will fall and may sell it or avoid it entirely. You will hear both terms in every market context, from stocks to forex to futures.
Markets are rarely moving purely in one direction. Most of the time a market is in one of three states: an uptrend, where prices are making progressively higher highs and higher lows over time; a downtrend, where prices are making lower highs and lower lows; or a sideways range, where prices are moving without clear direction, bouncing between a ceiling and a floor. Identifying which of these three states a market is in is often the first decision a trader makes before considering any position.
Volatility describes how much and how quickly a price is moving over a given period. A highly volatile market moves sharply in either direction, sometimes within minutes. A low-volatility market barely moves. Neither is inherently better. High volatility creates larger potential gains and larger potential losses in the same session. Low volatility offers smaller moves and requires more patience. For beginners, understanding the volatility of the market you are trading is important before sizing any position, because the same position size carries very different risk depending on how much the price typically moves in a day.
Reading the market: charts, candlesticks, and what volume tells you
A trading chart is a visual record of how a price has moved over time. The horizontal axis shows time, the vertical axis shows price. Every trading platform displays charts by default, and most default to candlestick charts, which pack more information into each data point than a simple line chart does.
A candlestick represents a single period of trading activity, which could be one minute, one hour, one day, or any interval the trader selects. Each candlestick shows four pieces of information: the price at which the period opened, the price at which it closed, the highest price reached during the period, and the lowest price reached. The body of the candlestick is the range between the open and the close. A green (or sometimes white) candle means the price closed higher than it opened, a bullish signal for that period. A red (or black) candle means the price closed lower than it opened, a bearish signal. The thin lines extending above and below the body are called wicks or shadows, and they show the high and low that were reached but not held. One candlestick tells a story about who was in control during that period: buyers or sellers.
Volume, in trading, is the number of shares, contracts, or units traded during a given period. It appears on most charts as a histogram at the bottom. Volume matters because it measures participation. A price move on high volume is generally considered more significant than the same move on low volume, because more traders are involved in the move. A breakout from a price level on low volume is often viewed with scepticism; the same breakout on heavy volume carries more weight.
Support and resistance are two of the most widely used concepts in trading, and they stay relevant regardless of the market, the timeframe, or the strategy. Support is a price level where, historically, buying has been strong enough to stop the price falling further. Resistance is a level where selling has been strong enough to stop the price rising further. Think of support as a floor and resistance as a ceiling. These levels are not exact lines. They are zones. And they can be broken: a price that falls through a strong support level often accelerates downward; a price that breaks above resistance often continues upward. That is why traders watch these levels carefully. They are the points where the balance between buyers and sellers is tested.
How trades are placed: orders, spreads, and the cost of execution
A market order is an instruction to buy or sell immediately at the best available current price. A limit order is an instruction to buy or sell only at a specific price, or better. That is the essential distinction between the two, and it matters in practice. If you place a market order to buy a stock, you get filled immediately but you accept whatever price the market is offering at that moment. If you place a limit order to buy the same stock at $50.00, your order will only execute if the price reaches $50.00 or below. You control the price but not whether the trade happens. Market orders guarantee execution. Limit orders guarantee price. When to use each depends on whether speed or price is more important for the specific trade.
Every market you trade has a bid price and an ask price. The bid is the highest price a buyer is currently willing to pay. The ask (also called the offer) is the lowest price a seller is currently willing to accept. When you buy, you pay the ask. When you sell, you receive the bid. The difference between the two is the spread, and it is a transaction cost you pay on every single trade, whether or not a broker charges a separate commission.
In the EUR/USD currency pair, for example, the spread on a standard retail forex account typically ranges from approximately 0.6 to 1.1 pips during liquid trading hours. OANDA's standard account averages 1.06 pips on EUR/USD as of April 2026, starting from 0.6 pips. Source: OANDA, oanda.com; compareforexbrokers.com, April 2026. Spreads widen during off-hours and around major data releases such as central bank interest rate decisions. One pip on a standard lot (100,000 units) represents $10. A 1.0 pip spread costs $10 to enter a trade before a single cent of profit is made. On a micro lot (1,000 units), the same spread costs $0.10. The numbers are different, but the principle is identical: every trade starts slightly negative because of the spread.
Slippage is the difference between the price you expected to receive on an order and the price you actually got. It occurs most often during fast-moving markets when the price changes in the fraction of a second between placing an order and its execution. It can also occur in thinly traded instruments where there are not enough buyers or sellers at the price you wanted. Slippage is usually small in liquid markets during normal conditions. In volatile conditions around major economic announcements, such as a central bank interest rate decision, slippage can be significant enough to materially affect a trade's outcome. Most experienced traders account for it in their risk calculations, particularly in markets known for sharp short-term moves. If you want to understand how to open a trading account to place these orders, how to start trading covers the practical steps.
Managing positions: stop-losses, take-profits, and the logic of risk/reward
A stop-loss is an order that automatically closes a position when the price moves against the trader by a specified amount. If you buy a stock at $100 and set a stop-loss at $95, your position closes automatically if the price falls to $95, limiting your loss to $5 per share. The stop-loss is not a prediction that the price will reach that level. It is a pre-decided answer to the question: how much am I willing to lose on this trade before I exit? Setting that answer before entering is one of the most fundamental practices in risk management.
One important nuance: stop-losses are not guaranteed to execute at the exact price specified. In fast-moving markets, or when a price gaps overnight (meaning it opens at a significantly different price than where it closed), the order may fill at a worse price than set. This is called gap risk, and it is most relevant to traders holding positions overnight or through scheduled events like earnings announcements or central bank meetings.
A take-profit order is the mirror image: it automatically closes a position when the price moves in the trader's favour by a specified amount, locking in a gain without requiring the trader to watch the screen. The discipline of setting both before a trade is placed, a stop-loss to define the loss and a take-profit to define the target, removes a significant amount of in-the-moment decision-making that tends to go badly under pressure.
The risk/reward ratio describes the relationship between the potential loss and the potential gain on a trade. A ratio of 1:2 means the trader is risking $100 to potentially make $200. A ratio of 1:3 means risking $100 to potentially make $300. The reason this matters is mathematical. A trader who consistently maintains a 1:2 risk/reward ratio can be right on fewer than half their trades and still be profitable overall. If ten trades are placed at 1:2 risk/reward, and six are losers and four are winners, the outcome is: six losses at $100 each ($600 lost), four wins at $200 each ($800 gained), net positive $200. Winning rate of 40%, net profit. That counterintuitive reality is why experienced traders talk about risk/reward almost as much as they talk about strategy.
Going long means buying an asset with the expectation that its price will rise. Going short means selling an asset (or selling a contract that represents it) with the expectation that the price will fall, then buying it back at a lower price to close the position. Most beginners trade long-only to start, because short-selling involves borrowing mechanisms and additional margin requirements that add complexity. The concept of shorting is worth understanding early, however, because traders who can only go long are limited to half the market's opportunities.
Leverage and margin: the concepts with the most consequence
Leverage in trading is the ability to control a position that is larger than the capital you have deposited. With 10:1 leverage, a $1,000 account controls a $10,000 position. A 1% move in the asset in your favour returns 10% on your deposited capital. A 1% move against you loses 10% of your deposited capital. The mathematics are symmetrical and they move fast. Used without a plan, leverage turns small losses into large ones faster than most beginners expect.
This is not a discouragement from using leverage. It is a statement of how it works. Leverage is a structural feature of futures, forex, and CFD markets, and using it is part of how these markets function. The important thing is understanding the actual position size you are controlling, not just the margin you have posted. A trader who thinks of a $200 deposit as a $200 trade and does not realise they are controlling a $2,000 or $10,000 position is likely to be surprised by how quickly losses accumulate.
Regulatory bodies set caps on how much leverage retail traders can access. In the United States, the Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA) cap retail forex leverage at 50:1 for major currency pairs. In the European Union, ESMA caps it at 30:1 for the same pairs. Source: nfa.futures.org and esma.europa.eu. Higher leverage is available in some futures markets and on some crypto platforms, and is structured differently in prop firm environments, where leverage is provided on a funded account rather than against a personal deposit.
Margin is the deposit required to open and maintain a leveraged position. It is not a fee; it is collateral. Initial margin is the amount required to open the position. Maintenance margin is the minimum amount required to keep it open. If your account balance falls below the maintenance margin level, the broker issues a margin call, which is a notification that additional funds must be deposited, or the position will be automatically closed, often at a loss. In fast-moving markets, margin calls can happen quickly. A $2,465 overnight maintenance margin on a Micro E-mini S&P 500 futures contract, for example, means that if the position moves against you by enough to reduce the account below that threshold, the broker may liquidate the position without further notice.

Market structure basics: liquidity, technical analysis, and indicators
Liquidity describes how easily an asset can be bought or sold without the transaction itself significantly affecting the price. A liquid market has many buyers and sellers active at any given moment, which means orders fill quickly, spreads are tight, and slippage is minimal. An illiquid market has fewer participants, wider spreads, and a higher risk that your order will move the price against you as it fills.
For beginners, liquidity is a practical concern. The major currency pairs in forex (EUR/USD, USD/JPY, GBP/USD) are among the most liquid markets in the world and are generally suitable for beginners for this reason. Large-cap stocks on major exchanges are also highly liquid. Thinly traded small-cap stocks, certain commodity futures contracts, and most cryptocurrencies outside the top few by market capitalisation carry materially higher liquidity risk. This does not mean beginners should avoid them entirely. It means the execution costs and risks are different, and should be understood before trading them.
Technical analysis is the practice of studying price charts and trading data, such as volume and historical price patterns, to forecast future price movements. It is one of the two main analytical frameworks traders use, the other being fundamental analysis, which evaluates an asset's underlying economic or financial value. A dedicated article covers technical analysis in full what is technical analysis in trading. The definition here is intentional: understand what it is before deciding whether it belongs in your approach.
Trading indicators are mathematical calculations applied to price and volume data, displayed as overlays or panels on a chart, used to help identify trends, momentum, and potential entry or exit points. Common examples include moving averages, which smooth out short-term price noise to show the underlying trend direction; the Relative Strength Index (RSI), which measures how quickly prices have been moving to identify overbought or oversold conditions; and the MACD (Moving Average Convergence Divergence), which tracks the relationship between two moving averages to signal potential trend changes. Each of these has a dedicated treatment in the indicators article, what are technical indicators. For now, the important thing to know is that indicators are tools to support a decision, not instructions to trade. No indicator is right all the time.
Vocabulary is the start, not the destination
None of these terms need to be memorised before trading begins. What matters is recognising them when they appear, knowing where to find a clear definition, and understanding enough about each concept to avoid the most costly misunderstandings, particularly around leverage, stop-loss placement, and the cost of spread on frequent trading. Fluency comes from context, from seeing these terms in use across real charts and real trades, not from reading a list.
The next step from here depends on where you are in the process. If you have not yet read through what trading actually is and how different markets work, what is trading is the place to start. If you understand the concept and are working out the practical steps of opening an account and choosing a market, how to start trading covers that in detail. Both are part of the same beginner foundation this article sits within.
