What is a spread and why is it critical for traders

Spread is one of the most important concepts in trading that everyone working in financial markets should understand. Simply put, the spread is the difference between the buyer’s price and the seller’s price. For example, if you see that an asset is offered at $100 (demand), and you can buy it for $99 (offer), the $1 difference is the spread. This is not just a number in the top corner of the screen; it is a real cost that affects every one of your trades.

How the spread affects your trades

Every time you buy or sell, the spread is a cost that many beginners forget. In forex, for example, if the EUR/USD pair is quoted with a demand of 1.1234 and an offer of 1.1236, the spread is 2 pips. Seems insignificant? Multiply that by 100 trades per day — and you get an amount that impacts profitability. For short-term traders, the spread is not just an expense; it is often a determining factor whether trading will be profitable.

Spread in different markets

The concept applies everywhere, but manifestations differ. In the stock market, a narrower spread indicates good liquidity — popular stocks have small spreads. In the bond market, the spread can represent a risk premium: the difference in yield between corporate bonds and government bonds shows how much more risk you are taking on. In the cryptocurrency space, spreads can be much wider, especially for less popular tokens, directly affecting entry and exit costs.

Liquidity and volatility: what widens the spread

Liquidity providers are always ready to widen the spread during instability. When the market erupts with emotions — due to economic news, geopolitical events, or sudden price jumps — spreads widen. This is a natural reaction: if no one is confident about the direction, traders demand higher compensation for risk. That’s why understanding the dynamics between volatility and the spread is critical for risk management, especially when entering and exiting positions during tense times.

Technology has changed the game

High-frequency trading and algorithmic trading significantly influence spread behavior. These technologies enable faster order processing and more efficient matching of buyers and sellers. The result: spreads tend to narrow, especially in liquid markets. However, this also means that traditional traders are competing with machines that process data faster than any human.

Practical recommendations for traders

The spread is not only an indicator of cost but also a sign of market health. When gaining access to trading, pay attention to spreads — they vary depending on the time of day, the liquidity of the pair, and the overall market condition. Planning your trading strategy should consider these costs. For active traders, choosing a platform with narrow spreads can provide a cumulative advantage, which becomes evident in the long run.

The spread is a fundamental concept that permeates all trading activities — from stocks to cryptocurrencies. Regardless of the instrument you trade, understanding how spreads impact your profitability gives you a competitive edge in the market.
