1. What is exchange trading

A learning guide for beginner traders

Exchange trading is the organized buying and selling of financial instruments in order to profit from changes in their price. In this lesson we will go through the basic concepts in simple language and with examples.

1.1. In simple words

Imagine an ordinary market. You can buy a product for $100 and later sell it for $120. Your profit: $120 − $100 = $20.

The same thing happens on a financial market. Only instead of a phone, a car or a sack of grain you can buy and sell cryptocurrencies, stocks, bonds, currencies, gold, oil, indexes, futures contracts and other financial instruments.

The key difference: on an organized market the trading process is standardized, and trades are made between participants through trading infrastructure.

1.2. What actually happens on the market

Every trade has two sides: the buyer wants to buy, the seller wants to sell. For example, one participant is ready to buy BTC at $100,000 and another is ready to sell BTC at $100,000. If the terms match, a trade happens.

After the trade, one participant receives the asset or a right under the contract, the other receives money or other consideration under the terms of the instrument.

1.3. Why does the price change?

The price changes because of the constant interaction of buyers' and sellers' orders, changes in liquidity and the expectations of market participants.

Put simply: rising demand relative to available supply can push the price up; rising supply relative to demand can push it down. This is a model for understanding, not a universal rule for every single candle.

1.4. What is an exchange?

An exchange is an organized trading venue where participants make trades in certain financial instruments under established rules.

Examples of traditional venues: NYSE, Nasdaq, CME. In cryptocurrencies, centralized crypto exchanges are used, for example Binance, Coinbase and Kraken.

1.5. Exchange, broker and terminal — what is the difference?

A trader is a participant who makes trades.

A broker is an intermediary that provides access to markets.

An exchange is the infrastructure of organized trading.

A trading terminal is a program or interface for analyzing the market and sending orders.

On traditional markets a trader often gets access to exchanges through a broker. In cryptocurrencies a user often deals with a crypto exchange directly through a website or an app.

1.6. What can you buy and sell?

• Cryptocurrencies — BTC, ETH and other assets.
• Stocks — shares in companies.
• Bonds — debt instruments.
• Forex — currency pairs, for example EUR/USD.
• Commodities — oil, gold, gas and other goods.
• Indexes — for example, the S&P 500 and Nasdaq-100.
• Futures and options — derivative financial instruments.

1.7. Spot trading

Spot means trading the asset itself, with settlement under the rules of the specific market. For example, when you buy 0.01 BTC at $100,000, the position is worth $1,000.

If the price then rises to $110,000, 0.01 BTC is worth $1,100. The income before fees and other costs is $100.

1.8. What is a short?

A short position lets you gain from a falling price. On the spot market you cannot simply sell an asset you do not own, so short positions are usually opened with margin trading, futures or other derivative instruments.

Important: a short carries additional risks and requires understanding how the specific instrument works.

1.9. Long and short

LONG — a position in which the trader gains when the price rises, all else being equal.

SHORT — a position in which the trader gains when the price falls, all else being equal.

1.10. What is an order?

Market Order — execute now at the available prices.

Limit Order — buy or sell at a set price or better. It does not guarantee execution.

1.11. What is an order book?

The order book shows the current orders of buyers and sellers. Sellers' offers (Ask) are at the top, buyers' orders (Bid) are below.

1.12. What is liquidity?

Liquidity shows how easily you can buy or sell a significant amount of an asset without materially affecting its price.

High liquidity usually means a deeper order book and lower price sensitivity to relatively small market orders. Low liquidity can lead to a stronger price impact.

1.13. What is slippage?

Slippage is a situation where the actual execution price differs from the expected one. For example, a large market order may be filled at several price levels in turn if there are not enough opposing orders at one price.

So a "buy now" order does not mean a guaranteed single execution price.

1.14. Why do people trade at all?

Speculation — an attempt to profit from price changes.

Investing — buying an asset with a long-term result in mind.

Hedging — reducing price risk.

Arbitrage — an attempt to exploit price differences between related markets or venues.

1.15. What is volatility?

Volatility describes the strength and speed of price changes. High volatility can create more trading opportunities, but it also increases risk.

1.16. Features of the crypto market

Many cryptocurrency markets are available 24/7; liquidity and volatility differ greatly between assets; spot and derivative instruments are available; some venues offer leverage.

High potential return does not mean low risk. On the contrary, sharp price moves can lead to fast losses.

1.17. What is leverage?

Leverage lets you control a position larger than your own capital, using borrowed funds or the mechanics of a derivative instrument.

A simplified example: capital of $1,000, notional leverage of 10× — a $10,000 position. A 1% move in the position corresponds to about $100 of result, which is about 10% of capital. The actual result depends on margin, fees, funding, liquidation and other conditions.

1.18. Why is leverage dangerous?

Leverage increases not only potential profit but also potential loss relative to your own capital. On an adverse move the position can be liquidated before the price changes by the full theoretical amount.

1.19. What is a fee?

An exchange or broker may charge a fee for operations. Besides it, there may be spread, funding, withdrawal fees, borrowing rates and other costs.

Profit before costs ≠ the trader's final profit.

1.20. What is a price chart?

A price chart shows how the price changed over time. One of the main ways to display price is Japanese candlesticks.

One candle can represent 1 minute, 5 minutes, 1 hour, 4 hours, a day, a week or another chosen period.

1.21. What is a timeframe?

Timeframe is the period that one candle represents. For example: 1M, 5M, 15M, 1H, 4H, 1D, 1W.

The same market can look different on different timeframes. A local rise on the hourly chart can happen inside a larger downward move on the daily chart.

1.22. What is a trend?

An uptrend is a sequence of higher highs and higher lows. A downtrend is a sequence of lower highs and lower lows. A sideways move is price oscillating within a range.

These definitions are simplified; real market structure can be mixed and change over time.

1.23. Support and resistance

Support is a price area where noticeable buyer interest appeared before. Resistance is an area where noticeable seller interest appeared before.

These are not magic lines and not guarantees of future price behavior.

1.24. What is fundamental analysis?

Fundamental analysis studies the factors that can affect an asset's value: company profit and revenue, interest rates, the economy, supply and demand, regulation, commodity inventories, the state of the network and other factors.

1.25. What is technical analysis?

Technical analysis studies price, volume, market structure, levels, patterns and indicators. It does not guarantee future price movement.

1.26. What is a trading strategy?

A trading strategy is a predefined set of rules by which a trader makes decisions: entry and exit conditions, position size, acceptable risk and actions in different scenarios.

The purpose of the rules is to reduce the influence of impulsive decisions.

1.27. What is risk management?

Risk management answers the question: "How much can I lose if my trading idea turns out to be wrong?"

For example, with capital of $10,000 and a planned risk of 1%, the maximum planned loss on one trade is $100. This is a simplified example; real risk depends on execution, gaps, liquidity and the conditions of the instrument.

1.28. What is Stop Loss?

Stop Loss is a preset exit level for an adverse price move. It helps limit the planned loss, but does not guarantee execution exactly at the specified price during sharp moves, gaps or low liquidity.

1.29. What is Take Profit?

Take Profit is a predefined level for locking in profit. Even before entry you can define the entry point, potential loss, potential profit and position size.

1.30. Example of a complete trade

Capital $10,000. Entry at BTC $100,000. Stop Loss $98,000. Take Profit $104,000. Size 0.2 BTC.

Potential loss: ($100,000 − $98,000) × 0.2 = $400. Potential profit: ($104,000 − $100,000) × 0.2 = $800. The simplified ratio of potential profit to risk is 1:2, excluding fees and slippage.

Profit and loss are shown here before fees, funding, slippage and other costs.

1.31. Why does one profitable trade prove nothing?

Trading should be evaluated over a series of trades. One successful trade may be a matter of chance, and one unsuccessful trade is not necessarily proof of a bad strategy. Statistics and following the rules matter.

1.32. What is expected value?

Suppose a strategy wins 40% of trades, the average profit is $300 and the average loss is $150. Simplified: 0.40 × $300 − 0.60 × $150 = +$30 per trade on average.

This is not a promise of profit but an illustration of why positive expected value is possible even with more losing trades.

1.33. Trading is not predicting the future

A more professional model: the trader builds a trading hypothesis and decides in advance what to do in a favorable and an unfavorable scenario. They do not have to know the future exactly.

1.34. Which markets does a trader study?

Cryptocurrencies, stocks, currencies and commodities share common principles of pricing and execution, but differ in trading hours, liquidity, regulation, available instruments and the structure of participants.

Specific rules, availability of instruments and regulation depend on the country, broker and exchange.

1.35. What is a trading session?

Traditional markets have set trading hours. During the day, activity can change as trading moves between the Asian, European and American sessions. The cryptocurrency market on centralized venues is usually available around the clock, seven days a week.

1.36. Who takes part in the market?

• retail traders
• investors
• banks
• funds
• market makers
• corporations
• hedgers
• arbitrage participants
• algorithmic traders

Different participants have different goals. A trader may look for a trading opportunity, a commodity producer may manage price risk, and a company may lock in the future cost of a purchase.

1.37. The most important idea for a beginner

1.38. A simple model of a trader

Market → analysis → trading idea → trade plan → entry / Stop Loss / Take Profit → result → statistics → strategy adjustment.

1.39. The main rule of the course

Trading does not work like this: "I know where the market is going → so I will earn." A more sustainable model: "I do not know the future → so I build scenarios, limit risk and work with probabilities."

This is especially important for cryptocurrencies, where sharp price moves can happen within a very short time.
