I just realized that many people don't really understand what spread is, even though it directly affects their daily trading costs. So today I want to share some knowledge about this.

Simply put, spread is the difference between the bid price and the ask price of a currency pair. When you want to buy, you buy at the ask price (higher). When you want to sell, you sell at the bid price (lower). This difference is the profit for the broker, and it is also the first cost you pay each time you open a trade.

Spreads are usually measured in pips. For major currency pairs like EUR/USD, 1 pip = 0.0001. For example, if EUR/USD has a bid of 1.1021 and an ask of 1.1023, then the spread is 2 pips. If you trade 1 standard lot, you will lose about 20 USD just because of this spread.

There are two types of spreads I often encounter: fixed spread and floating spread. Fixed spread always stays the same, which is good if you want to predict costs, but the problem is when the market is highly volatile, the broker may refuse the trade or requote you at a new price. Floating spread, on the other hand, always changes according to market conditions — it can narrow when liquidity is good, but widen during unstable market conditions.

I see that three main factors influence the spread level. First is liquidity — when more people trade, the spread tends to narrow. Second is trading volume — popular pairs like EUR/USD or GBP/USD always have better spreads than less traded pairs. Third is volatility — when the market moves strongly, the spread can widen significantly.

There are two times when spreads tend to widen very sharply. One is during low liquidity hours (between trading sessions), when fewer people are trading, so the bid-ask spread becomes wider. The second is before and after major economic news — during these times, brokers often widen spreads to protect themselves from sudden price swings.

So how can you minimize spread costs? I have two ways. One is to trade only during high liquidity hours, when there are many buyers and sellers. At that time, spreads are at their lowest. The second is to focus on trading popular currency pairs — they always have narrower spreads because many market makers compete.

If you are a scalper or day trader, spread costs are very important to control. But if you trade swing or long-term, spreads are less impactful. Anyway, understanding spreads helps you better manage trading costs and increases your chances of profit.
