What Is the Spread in Trading?

If you have ever bought something and noticed that the price to buy was slightly higher than the price to sell, you already understand the spread in trading. The spread is the gap between the highest price a buyer is willing to pay and the lowest price a seller is willing to accept. It is a cost you pay on every single trade, and most beginners never even realize it is there.

What is the spread in trading?

When you look at any market, you will see two prices. The bid is the best price someone is willing to buy at right now. The ask (sometimes called the offer) is the best price someone is willing to sell at right now. The spread is the difference between those two numbers.

Think of it like a currency exchange booth at an airport. They will buy your euros at one price and sell them to you at a slightly higher price. That gap is how they make money. In trading, the spread works the same way. Market makers and exchanges sit in the middle, and the spread is part of how they get paid for keeping the market running.

Why the spread matters for day traders

Every time you enter a trade, you start slightly in the red because of the spread. If the spread on a stock is 10 cents and you buy at the ask, you would need the price to move at least 10 cents in your favor just to break even if you sold at the bid. That might sound small, but it adds up fast when you are taking multiple trades a day.

This is one of the reasons I tell people I mentor to be selective about their trades. The more trades you take, the more times you pay the spread. If you are overtrading, the spread alone can turn a breakeven strategy into a losing one.

What makes the spread tight or wide

The spread is not a fixed number. It changes based on a few things.

• Liquidity. Markets with lots of buyers and sellers have tight spreads because there is heavy competition to fill orders. Something like S&P 500 futures during New York hours might have a spread of just one tick. A small altcoin at 3 a.m. could have a spread 50 times wider.
• Volatility. When a big news event hits, market makers pull back and the spread widens because nobody wants to be on the wrong side of a fast move.
• Time of day. Spreads are tightest during the main trading session when the most participants are active. Outside those hours, fewer players means wider gaps.

This is exactly why session timing matters. Trading during the liquid hours means you pay less on every entry and exit.

Spread in crypto vs futures vs stocks

The spread varies a lot depending on what you trade. In highly liquid futures like the E-mini S&P 500, the spread during regular hours is typically just one tick. For major crypto pairs like Bitcoin on a large exchange, the spread is usually tight but can blow out during fast moves. Smaller altcoins and lower-volume markets tend to have much wider spreads, which means higher costs on every trade.

If you are day trading crypto, paying attention to the spread is not optional. A wide spread on a low-volume coin can eat your entire profit target before the trade even moves in your favor.

How to reduce the cost of the spread

You cannot eliminate the spread, but you can shrink the amount you pay.

• Trade liquid markets. Stick to assets with high volume and tight spreads. This alone is the biggest lever.
• Trade during peak hours. The main session for your market is when spreads are tightest.
• Use limit orders. A limit order sits on the order book at your price instead of crossing the spread to fill immediately. You become the bid or the ask instead of paying someone else to fill you.
• Take fewer, higher-quality trades. Every trade costs you the spread. Fewer entries means less total friction.

Spread and your trading plan

When you trade for a living, every cost matters. The spread is one of those costs that does not show up on any commission receipt, but it is there on every single trade. I factor it into every strategy I test. If a setup only works when spreads are perfect, it does not actually work. A real edge survives the spread, the commission, and the slippage combined.

Understanding the spread will not make you a better predictor of where price goes next. But it will make you a more honest accountant of your own results, and that honesty is what separates traders who last from traders who quietly bleed out wondering why their “winning” strategy keeps losing money.

Common questions

What is the spread in simple terms?

The spread is the small gap between the price you can buy at and the price you can sell at. It is a built-in cost on every trade, similar to the markup at a currency exchange booth.

Why is the spread important for day traders?

Because day traders enter and exit many times, they pay the spread on every round trip. Over dozens or hundreds of trades, a wide spread can turn a profitable strategy into a losing one.

What causes the spread to widen?

Low liquidity, high volatility, and trading outside of peak market hours all cause spreads to widen. During major news events, market makers step back and the gap between buyers and sellers grows.

How can I reduce the spread I pay?

Trade liquid, high-volume markets during peak hours, and use limit orders instead of market orders. Limit orders let you set your price rather than crossing the spread to fill immediately.
