What is a spread and why traders should not ignore it

The spread is one of the key parameters that every market participant must understand thoroughly. It refers to the difference between the price at which a buyer is willing to buy (bid) and the price at which a seller is willing to sell (ask). It sounds simple, but this difference determines the cost of your trade and influences the final profitability of trading.

How the spread works in different markets

In the stock market the spread serves as an indicator of market health. A narrow spread indicates high liquidity and active traders, while a wide spread signals a lack of sufficient active participants. Imagine: if a stock is traded with a bid of 100 and an ask of 100.5, the spread is minimal. But if the gap between bid and ask widens to 100 and 101, it means the market is less active.

In the bond market the spread takes another form — it shows the difference in yields between government and corporate bonds. This is called a risk premium. The wider this difference, the more risk investors see in corporate debt and the greater compensation they demand.

In the currency market the spread is critically important. When you see a quote EUR/USD as 1.1234/1.1236, the spread is 2 pips. This is its cost to you on each trade. Forex spreads depend on current volatility, trading volume in the network, and the importance of economic news.

Why investors need to consider the spread

The spread directly eats into your profit. Imagine you bought a security with a wide spread of 2 points. To break even, it must increase by those 2 points. If the spread is narrow — just 0.5 points — your breakeven point is much closer. For short-term traders or those working with large volumes, accumulating spreads can significantly impact results.

How technology has changed spreads

The development of algorithmic trading and high-frequency trading systems has increased market efficiency. Computers instantly connect buyers and sellers, which narrows spreads. This automation has made trading more accessible and cheaper for ordinary investors.

Volatility and spread widening

When the market is volatile, spreads widen. During important economic announcements or geopolitical shocks, liquidity providers increase their requirements by widening spreads. This is a natural protective mechanism. Understanding this pattern helps traders better plan entries and exits during such periods.

Spread in cryptocurrency trading

On crypto platforms, spreads vary depending on the pair and platform. Popular exchanges show different spreads for the same pairs because liquidity differs. Some platforms have a deeper order book, leading to narrower spreads. Crypto traders should compare spreads across platforms to minimize costs.

Conclusion

The spread is a fundamental element of trading across all markets. It’s not just a number between buy and sell prices; it’s a window into market liquidity and risk. Whether you’re working with stocks, currencies, bonds, or cryptocurrencies, understanding spread dynamics is an essential skill for making informed trading decisions and managing risks. Controlling costs associated with spreads can significantly improve your trading efficiency.
